config ESP_TIMER_PROFILING
bool "Enable esp_timer profiling features"
default n
help
If enabled, esp_timer_dump will dump information such as number of times the timer was started, number of
times the timer has triggered, and the total time it took for the callback to run. This option has some
effect on timer performance and the amount of memory used for timer storage, and should only be used for
debugging/testing purposes.
config ESP_ERR_TO_NAME_LOOKUP
bool "Enable lookup of error code strings"
default "y"
help
Functions esp_err_to_name() and esp_err_to_name_r() return string representations of error codes from a
pre-generated lookup table. This option can be used to turn off the use of the look-up table in order to
save memory but this comes at the price of sacrificing distinguishable (meaningful) output string
representations.
config ESP_SYSTEM_EVENT_QUEUE_SIZE
int "System event queue size"
default 32
help
Config system event queue size in different application.
config ESP_SYSTEM_EVENT_TASK_STACK_SIZE
int "Event loop task stack size"
default 2304
help
Config system event task stack size in different application.
config ESP_MAIN_TASK_STACK_SIZE
int "Main task stack size"
default 3584
help
Configure the "main task" stack size. This is the stack of the task
which calls app_main(). If app_main() returns then this task is deleted
and its stack memory is freed.
config ESP_IPC_TASK_STACK_SIZE
int "Inter-Processor Call (IPC) task stack size"
default 1024
range 512 65536 if !ESP32_APPTRACE_ENABLE
range 2048 65536 if ESP32_APPTRACE_ENABLE
help
Configure the IPC tasks stack size. One IPC task runs on each core
(in dual core mode), and allows for cross-core function calls.
See IPC documentation for more details.
The default stack size should be enough for most common use cases.
It can be shrunk if you are sure that you do not use any custom
IPC functionality.
config ESP_TIMER_TASK_STACK_SIZE
int "High-resolution timer task stack size"
default 3584
range 2048 65536
help
Configure the stack size of esp_timer/ets_timer task. This task is used
to dispatch callbacks of timers created using ets_timer and esp_timer
APIs. If you are seing stack overflow errors in timer task, increase
this value.
Note that this is not the same as FreeRTOS timer task. To configure
FreeRTOS timer task size, see "FreeRTOS timer task stack size" option
in "FreeRTOS" menu.
choice ESP_CONSOLE_UART
prompt "UART for console output"
default ESP_CONSOLE_UART_DEFAULT
help
Select whether to use UART for console output (through stdout and stderr).
- Default is to use UART0 on pins GPIO1(TX) and GPIO3(RX).
- If "Custom" is selected, UART0 or UART1 can be chosen,
and any pins can be selected.
- If "None" is selected, there will be no console output on any UART, except
for initial output from ROM bootloader. This output can be further suppressed by
bootstrapping GPIO13 pin to low logic level.

Due of a ROM bug, UART2 is not supported for console output
via ets_printf.

config ESP_INT_WDT
bool "Interrupt watchdog"
default y
help
This watchdog timer can detect if the FreeRTOS tick interrupt has not been called for a certain time,
either because a task turned off interrupts and did not turn them on for a long time, or because an
interrupt handler did not return. It will try to invoke the panic handler first and failing that
reset the SoC.
config ESP_INT_WDT_TIMEOUT_MS
int "Interrupt watchdog timeout (ms)"
depends on ESP_INT_WDT
default 300 if !ESP32_SPIRAM_SUPPORT

range 10 10000
help
The timeout of the watchdog, in miliseconds. Make this higher than the FreeRTOS tick rate.
config ESP_INT_WDT_CHECK_CPU1
bool "Also watch CPU1 tick interrupt"
depends on ESP_INT_WDT && !FREERTOS_UNICORE
default y
help
Also detect if interrupts on CPU 1 are disabled for too long.
config ESP_TASK_WDT
bool "Initialize Task Watchdog Timer on startup"
default y
help
The Task Watchdog Timer can be used to make sure individual tasks are still
running. Enabling this option will cause the Task Watchdog Timer to be
initialized automatically at startup. The Task Watchdog timer can be
initialized after startup as well (see Task Watchdog Timer API Reference)
config ESP_TASK_WDT_PANIC
bool "Invoke panic handler on Task Watchdog timeout"
depends on ESP_TASK_WDT
default n
help
If this option is enabled, the Task Watchdog Timer will be configured to
trigger the panic handler when it times out. This can also be configured
at run time (see Task Watchdog Timer API Reference)
config ESP_TASK_WDT_TIMEOUT_S
int "Task Watchdog timeout period (seconds)"
depends on ESP_TASK_WDT
range 1 60
default 5
help
Timeout period configuration for the Task Watchdog Timer in seconds.
This is also configurable at run time (see Task Watchdog Timer API Reference)
config ESP_TASK_WDT_CHECK_IDLE_TASK_CPU0
bool "Watch CPU0 Idle Task"
depends on ESP_TASK_WDT
default y
help
If this option is enabled, the Task Watchdog Timer will watch the CPU0
Idle Task. Having the Task Watchdog watch the Idle Task allows for detection
of CPU starvation as the Idle Task not being called is usually a symptom of
CPU starvation. Starvation of the Idle Task is detrimental as FreeRTOS household
tasks depend on the Idle Task getting some runtime every now and then.
config ESP_TASK_WDT_CHECK_IDLE_TASK_CPU1
bool "Watch CPU1 Idle Task"
depends on ESP_TASK_WDT && !FREERTOS_UNICORE
default y
help
If this option is enabled, the Task Wtachdog Timer will wach the CPU1
Idle Task.
