Header definitions for a FreeRTOS ringbuffer object
A ringbuffer instantiated by these functions essentially acts like a FreeRTOS queue, with the
difference that it's strictly FIFO and with the main advantage that you can put in randomly-sized
items. The capacity, accordingly, isn't measured in the amount of items, but the amount of memory
that is used for storing the items. Dependent on the size of the items, more or less of them will
fit in the ring buffer.
This ringbuffer tries to be efficient with memory: when inserting an item, the item data will
be copied to the ringbuffer memory. When retrieving an item, however, a reference to ringbuffer
memory will be returned. The returned memory is guaranteed to be 32-bit aligned and contiguous.
The application can use this memory, but as long as it does, ringbuffer writes that would write
to this bit of memory will block.
The requirement for items to be contiguous is slightly problematic when the only way to place
the next item would involve a wraparound from the end to the beginning of the ringbuffer. This can
be solved (or not) in a few ways:
- type = RINGBUF_TYPE_ALLOWSPLIT: The insertion code will split the item in two items; one which fits
in the space left at the end of the ringbuffer, one that contains the remaining data which is placed
in the beginning. Two xRingbufferReceive calls will be needed to retrieve the data.
- type = RINGBUF_TYPE_NOSPLIT: The insertion code will leave the room at the end of the ringbuffer
unused and instead will put the entire item at the start of the ringbuffer, as soon as there is
enough free space.
- type = RINGBUF_TYPE_BYTEBUF: This is your conventional byte-based ringbuffer. It does have no
overhead, but it has no item contiguousness either: a read will just give you the entire written
buffer space, or the space up to the end of the buffer, and writes can be broken up in any way
possible. Note that this type cannot do a 2nd read before returning the memory of the 1st.
The maximum size of an item will be affected by this decision. When split items are allowed, it's
acceptable to push items of (buffer_size)-16 bytes into the buffer. When it's not allowed, the
maximum size is (buffer_size/2)-8 bytes. The bytebuf can fill the entire buffer with data, it has
no overhead.

/*
* Test backported deletion behavior by creating tasks of various affinities and
* check if the task memory is freed immediately under the correct conditions.
*
* The behavior of vTaskDelete() has been backported form FreeRTOS v9.0.0. This
* results in the immediate freeing of task memory and the immediate execution
* of deletion callbacks under the following conditions...
* - When deleting a task that is not currently running on either core
* - When deleting a task that is pinned to the same core (with respect to
* the core that calls vTaskDelete()
*
* If the two conditions are not met, freeing of task memory and execution of
* deletion callbacks will still be carried out by the Idle Task.

config SPI_FLASH_WARN_SETTING_ZERO_TO_ONE
bool "Log warning if writing zero bits to ones"
depends on SPI_FLASH_VERIFY_WRITE

help
If this option is enabled, any SPI flash write which tries to set zero bits in the flash to
ones will log a warning. Such writes will not result in the requested data appearing identically
in flash once written, as SPI NOR flash can only set bits to one when an entire sector is erased.
After erasing, individual bits can only be written from one to zero.
Note that some software (such as SPIFFS) which is aware of SPI NOR flash may write one bits as an
optimisation, relying on the data in flash becoming a bitwise AND of the new data and any existing data.
Such software will log spurious warnings if this option is enabled.

The ``program`` array is an array of ``ulp_insn_t``, i.e. ULP coprocessor instructions. Each ``I_XXX`` preprocessor define translates into a single 32-bit instruction. Arguments of these preprocessor defines can be register numbers (``R0 — R3``) and literal constants. See `ULP coprocessor instruction defines`_ section for descriptions of instructions and arguments they take.
.. note::
Because some of the instruction macros expand to inline function calls, defining such array in global scope will cause the compiler to produce an "initializer element is not constant" error. To fix this error, move the definition of instructions array into local scope.
Load and store instructions use addresses expressed in 32-bit words. Address 0 corresponds to the first word of ``RTC_SLOW_MEM`` (which is address 0x50000000 as seen by the main CPUs).
To generate branch instructions, special ``M_`` preprocessor defines are used. ``M_LABEL`` define can be used to define a branch target. Label identifier is a 16-bit integer. ``M_Bxxx`` defines can be used to generate branch instructions with target set to a particular label.

.. _floating-points:
Floating Point Aritmetic
------------------------
The ESP32 supports hardware acceleration of single precision floating point
arithmetic (``float``) via Floating Point Units (FPU, also known as coprocessors)
attached to each core. The use of the FPUs imposes some behavioral restrictions
on ESP-IDF FreeRTOS.
ESP-IDF FreeRTOS implements Lazy Context Switching for FPUs. In other words,
the state of a core's FPU registers are not immediately saved when a context
switch occurs. Therefore, tasks that utilize ``float`` must be pinned to a
particular core upon creation. If not, ESP-IDF FreeRTOS will automatically pin
the task in question to whichever core the task was running on upon the task's
first use of ``float``. Likewise due to Lazy Context Switching, interrupt service
routines must also not use ``float``.
ESP32 does not support hardware acceleration for double precision floating point
arithmetic (``double``). Instead ``double`` is implemented via software hence the
behavioral restrictions with regards to ``float`` do not apply to ``double``. Note
that due to the lack of hardware acceleration, ``double`` operations may consume
significantly larger amount of CPU time in comparison to ``float``.
.. _task-deletion:
Task Deletion
-------------
FreeRTOS task deletion prior to v9.0.0 delegated the freeing of task memory
entirely to the Idle Task. Currently, the freeing of task memory will occur
immediately (within :cpp:func:`vTaskDelete`) if the task being deleted is not currently
running or is not pinned to the other core (with respect to the core
:cpp:func:`vTaskDelete` is called on). TLSP deletion callbacks will also run immediately
if the same conditions are met.
However, calling :cpp:func:`vTaskDelete` to delete a task that is either currently
running or pinned to the other core will still result in the freeing of memory
being delegated to the Idle Task.
.. _deletion-callbacks:
Thread Local Storage Pointers & Deletion Callbacks
--------------------------------------------------
Thread Local Storage Pointers are pointers stored directly in the TCB which
allows each task to have a pointer to a data structure containing that is
specific to that task. However vanilla FreeRTOS provides no functionality to
free the memory pointed to by the Thread Local Storage Pointers. Therefore if
the memory pointed to by the Thread Local Storage Pointers is not explicitly
freed by the user before a task is deleted, memory leak will occur.
Thread Local Storage Pointers (TLSP) are pointers stored directly in the TCB.
TLSP allow each task to have its own unique set of pointers to data structures.
However task deletion behavior in vanilla FreeRTOS does not automatically
free the memory pointed to by TLSP. Therefore if the memory pointed to by
TLSP is not explicitly freed by the user before task deletion, memory leak will
occur.
ESP-IDF FreeRTOS provides the added feature of deletion callbacks. These
deletion callbacks are used to automatically free the memory pointed to by the
Thread Local Storage Pointers when a task is deleted. Each Thread Local Storage
Pointer can have its own call back, and these call backs are called when the
Idle tasks cleans up a deleted tasks.
ESP-IDF FreeRTOS provides the added feature of Deletion Callbacks. Deletion
Callbacks are called automatically during task deletion to free memory pointed
to by TLSP. Each TLSP can have its own Deletion Callback. Note that due to the
to :ref:`task-deletion` behavior, there can be instances where Deletion
Callbacks are called in the context of the Idle Tasks. Therefore Deletion
Callbacks **should never attempt to block** and critical sections should be kept
as short as possible to minimize priority inversion.
Vanilla FreeRTOS sets a Thread Local Storage Pointers using
``vTaskSetThreadLocalStoragePointer()`` whereas ESP-IDF FreeRTOS sets a Thread
Local Storage Pointers and Deletion Callbacks using
``vTaskSetThreadLocalStoragePointerAndDelCallback()`` which accepts a pointer
to the deletion call back as an extra parameter of type
```TlsDeleteCallbackFunction_t``. Calling the vanilla FreeRTOS API
``vTaskSetThreadLocalStoragePointer()`` is still valid however it is internally
defined to call ``vTaskSetThreadLocalStoragePointerAndDelCallback()`` with a
``NULL`` pointer as the deletion call back. This results in the selected Thread
Local Storage Pointer to have no deletion call back.
Deletion callbacks are of type
``void (*TlsDeleteCallbackFunction_t)( int, void * )`` where the first parameter
is the index number of the associated TLSP, and the second parameter is the
TLSP itself.
In IDF the FreeRTOS thread local storage at index 0 is reserved and is used to implement
the pthreads API thread local storage (pthread_getspecific() & pthread_setspecific()).
Other indexes can be used for any purpose, provided
:ref:`CONFIG_FREERTOS_THREAD_LOCAL_STORAGE_POINTERS` is set to a high enough value.
Deletion callbacks are set alongside TLSP by calling
:cpp:func:`vTaskSetThreadLocalStoragePointerAndDelCallback`. Calling the vanilla
FreeRTOS function :cpp:func:`vTaskSetThreadLocalStoragePointer` will simply set the
TLSP's associated Deletion Callback to `NULL` meaning that no callback will be
called for that TLSP during task deletion. If a deletion callback is `NULL`,
users should manually free the memory pointed to by the associated TLSP before
task deletion in order to avoid memory leak.
For more details see :component_file:`freertos/include/freertos/task.h`
:ref:`CONFIG_FREERTOS_THREAD_LOCAL_STORAGE_POINTERS` in menuconfig can be used

ULP coprocessor is clocked from RTC_FAST_CLK, which is normally derived from the internal 8MHz oscillator. Applications which need to know exact ULP clock frequency can calibrate it against the main XTAL clock::
#include "soc/rtc.h"
// calibrate 8M/256 clock against XTAL, get 8M/256 clock period
uint32_t rtc_8md256_period = rtc_clk_cal(RTC_CAL_8MD256, 100);
uint32_t rtc_fast_freq_hz = 1000000ULL * (1 << RTC_CLK_CAL_FRACT) * 256 / rtc_8md256_period;
ULP coprocessor needs 2 clock cycle to fetch each instuction (fetching is not pipelined), plus certain number of cycles to execute, depending on the instruction. See description of each instruction for details on the execution time.
Note that when accessing RTC memories and RTC registers, ULP coprocessor has lower priority than the main CPUs. This means that ULP coprocessor execution may be suspended while the main CPUs access same memory region as the ULP.

See http://www.throwtheswitch.org/unity for more information about writing tests in Unity.
Add multiple devices test cases
-------------------------------
The normal test cases will be executed on one DUT (Device Under Test). Components need to communicate with each other (like GPIO, SPI ...) can't be tested with normal test cases.
Multiple devices test cases support writing and running test with multiple DUTs.
Here's an example of multiple devices test case::
void gpio_master_test()
{
gpio_config_t slave_config = {
.pin_bit_mask = 1 << MASTER_GPIO_PIN,
.mode = GPIO_MODE_INPUT,
};
gpio_config(&slave_config);
unity_wait_for_signal("output high level");
TEST_ASSERT(gpio_get_level(MASTER_GPIO_PIN) == 1);
}
void gpio_slave_test()
{
gpio_config_t master_config = {
.pin_bit_mask = 1 << SLAVE_GPIO_PIN,
.mode = GPIO_MODE_OUTPUT,
};
gpio_config(&master_config);
gpio_set_level(SLAVE_GPIO_PIN, 1);
unity_send_signal("output high level");
}
TEST_CASE_MULTIPLE_DEVICES("gpio multiple devices test example", "[driver]", gpio_master_test, gpio_slave_test);
The macro ``TEST_CASE_MULTIPLE_DEVICES`` is used to declare multiple devices test cases.
First argument is test case name, second argument is test case description.
From the third argument, upto 5 test functions can be defined, each function will be the entry point of tests running on each DUT.
Running test cases from different DUTs could require synchronizing between DUTs. We provide ``unity_wait_for_signal`` and ``unity_send_signal`` to support synchronizing with UART.
As the secnario in the above example, slave should get GPIO level after master set level. DUT UART console will prompt and requires user interaction:
DUT1 (master) console::
Waiting for signal: [output high level]!
Please press "Enter" key to once any board send this signal.
DUT2 (slave) console::
Send signal: [output high level]!
Once the signal is set from DUT2, you need to press "Enter" on DUT1, then DUT1 unblocks from ``unity_wait_for_signal`` and starts to change GPIO level.

Overview
--------
ESP32-PICO-KIT V4 is a mini development board based on the ESP32-PICO-D4 SIP module produced by `Espressif <https://espressif.com>`_. For easy interfacing, all the IO signals and system power on ESP32-PICO-D4 are led out through two 20 x 0.1" pitch header pads on both sides of the development board. To make the ESP32-PICO-KIT V4 fit into mini breadboards, the header pads are populated with two 17 pin headers. Remaining 2 x 3 pads grouped on one side of the board besides the antenna are not populated. If required, the additional 2 x 3 pin headers may be soldered later by the user. The development board integrates a USB-UART Bridge circuit, allowing the developers to connect the board to a PC's USB port for downloads and debugging.
ESP32-PICO-KIT V4 is a mini development board produced by `Espressif <https://espressif.com>`_. At the core of this board is the ESP32-PICO-D4, a System-in-Package (SIP) module with complete Wi-Fi and Bluetooth functionalities. Comparing to other ESP32 chips, the ESP32-PICO-D4 integrates several peripheral components in one single package, that otherwise would need to be installed separately. This includes a 40 MHz crystal oscillator, 4 MB flash, filter capacitors and RF matching links in. This greatly reduces quantity and costs of additional components, subsequent assembly and testing cost, as well as overall product complexity.
The development board integrates a USB-UART Bridge circuit, allowing the developers to connect the board to a PC's USB port for downloads and debugging.
For easy interfacing, all the IO signals and system power on ESP32-PICO-D4 are led out through two rows of 20 x 0.1" pitch header pads on both sides of the development board. To make the ESP32-PICO-KIT V4 fit into mini breadboards, the header pads are populated with two rows of 17 pin headers. Remaining 2 x 3 pads grouped on each side of the board besides the antenna are not populated. The remaining 2 x 3 pin headers may be soldered later by the user.
.. note::
The 2 x 3 pads not populated with pin headers are internally connected to the flash memory embedded in the ESP32-PICO-D4 SIP module. For more details see module's datasheet in :ref:`get-started-pico-kit-v4-related-documents`.
The 2 x 3 pads not populated with pin headers are internally connected to the flash memory embedded in the ESP32-PICO-D4 SIP module. For more details see module's datasheet in `Related Documents`_.

.. _get-started-pico-kit-v4-pin-notes:
**Notes to** `Pin Descriptions`_
1. This pin is connected to the flash pin of ESP32-PICO-D4.
2. When used as ADC_PRE_AMP, connect 270 pF capacitors between: (a) SENSOR_VP and IO37, (b) SENSOR_VN and IO38.
3. 32.768 kHz crystal oscillator: (a) input, (b) output.
4. This pin is connected to the pin of the USB bridge chip on the board.
5. The operating voltage of ESP32-PICO-KIT’s embedded SPI flash is 3.3V. Therefore, the strapping pin MTDI should hold bit ”0” during the module power-on reset.
