Initial version of freemodbus master port files have been added to ESP-IDF based on https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32.
The overall repository license, at the time of adding these files, has been BSD 3-clause. However at that time, several port files carried LGPL license headers. As the author of these files confirmed in https://github.com/armink/FreeModbus_Slave-Master-RTT-STM32/issues/61#issuecomment-977828450, this wasn't intentional. ESP-IDF version of modbus master port has been rewritten to target FreeRTOS instead of RT-Thread, but the license headers remained from the original version. This commit corrects this, replacing the license of these files with BSD 3-clause.
freemodbus: fix issues when modbus master and slave work simultaneously
fix slave destroy bug when master and slave init simultaneously
add additional timer group options for master (https://github.com/espressif/esp-idf/issues/4699)
Closes IDF-3012 and IDFGH-2619
See merge request espressif/esp-idf!12961
fix slave destroy bug when master and slave init simultaneously
add additional timer group options for master
fix master and slave use the same timer group index (https://github.com/espressif/esp-idf/issues/4699)
Current lwip implementation does not support deleting a task which is
actively waiting on `select()` or `poll()` API.
Therefore we have to make sure that `select()` exits to deallocate its internal
callback before deleting the task. This is achieved by a shutdown
semaphore which informs the client once the `select()` exitted.
fix slave
add multi register area descriptors into concrete port (initial)
add create/destroy of area descriptors into concrete port
add the list of descriptors in common slave interface structure and init/destroy in concrete slave port
move r/w callback functions into common slave
final update of common slave interface wrappers add override API option in concrete port
update slave examples to check new feature
Add TCP port files to provide Modbus TCP interface for communication
Add freemodbus add tcp support for common master/slave iface and tcp example based on socket API
The communication between master and slave checked for each example serial_master, serial_slave (use ModbusPoll TCP)
update tcp example according netif changes, fix ci issues
update TCP slave implementation
update example_test.py to to set IP through stdin
update API documentation
event bit instead of semahore to lock communication resource
update default options and master/slave port files
Closes https://github.com/espressif/esp-idf/issues/858
Closes IDF-452
check master read write functions with array of registers)
fix master serial processing code and modbus controller to work with register array
modbus_master: add reading and writing of test value array (58 registers) to check failure is gone
remove parameter temporary buffer from modbus controller to allow more than 24 byte writes
driver: fix issue with TOUT feature
driver: fix uart_rx_timeout issue
driver: fix issue with rxfifo_tout_int_raw not triggered when received fifo_len = 120 byte and all bytes read out of fifo as result of rxfifo_full_int_raw
driver: add function uart_internal_set_always_rx_timeout() to always handle tout interrupt
examples: call uart_internal_set_always_rx_timeout() to handle tout interrupt correctly
examples: update examples to use tout feature
driver: reflect changes of uart_set_always_rx_timeout() function, change uart.c
driver: change conditions to trigger workaround for tout feature in uart.c
driver: change uart_set_always_rx_timeout()
freemodbus: fix tabs, remove commented code
driver: remove uart_ll_is_rx_idle()
add support of modbus master ascii
rename base dir name of master and slave example to be mb_slave, mb_master to avoid conflict with sdio/slave example test
add Kconfig option to enable ASCII and RTU mode separately
update ASCII options + remove cast for errors
added baudrate for examples into Kconfig
updated magic numbers for timer timeout
put ascii private definitions into one file
1. add hal and low-level layer for timer group
2. add callback functions to handle interrupt
3. add timer deinit function
4. add timer spinlock take function
place timer interrupt handler into flash by default;
add default settings for timer and UART interrupts to place them into IRAM into example defaults;
CONFIG_FMB_TIMER_PORT_ENABLED default = n, when enabled, the UART_ISR_IN_IRAM set to y
place timer handler functions into IRAM
update timer port handlers
fix communication issues
fix offset issue in example
add kconfig option to place handlers into IRAM
adds timer interrupt handle and free it in vMBXXXPortTimerClose() in master and slave timer port
assign modbus controller interface pointer to NULL in destroy function after free
