Unity in ESP v4

Hi

Could someone give me some suggestions how to support Unity testing in ESP version 4 by using CMake and idf.py?

thanks

i2c_master_cmd_begin() fails

Hi

I am using the ESP32 function i2c_master_cmd_begin() as:

err = i2c_master_cmd_begin(I2C_NUM_0, cmd, 1000 / portTICK_RATE_MS);

and every now and then this function returns -1 (which is an error).

Would there be a reason for this to happen?

thanks,

ledc_set_freq generates a reboot

Hi I'm calling this function: err = ledc_set_freq(pPwmDarams->tConfig.speed_mode, pPwmDarams->tConfig.timer_num, freq); with the values: speed_mode=0 timer_num=3 freq=2000 This generates a reboot of the ESP32. The backtrace can be found below. Any ideas about what may be happening? -----------------...

Re: vTaskSuspendAll() and vTaskEndScheduler()

In fact what I want is to suspend all the tasks with the exception of the one running (the one calling the function to suspend all the other tasks). The running task should continue to run. I cannot find such call so I assume that I need to suspend all the tasks with the exception the one that is ru...

Re: vTaskSuspendAll() and vTaskEndScheduler()

In fact would I would like to have is a FreeRTOS function that stops all the other tasks with the exception of the task calling that function. Can the stop scheduler do this? Of course I can keep all the handles of the tasks that I have created and suspend one by one, by this is much more work and a...

Re: vTaskSuspendAll() and vTaskEndScheduler()

This is the code: The Delay_ms() is just a for loop. Can ESP_LOGI be called after vTaskSuspendAll() ? void Error ( const char *file, const char *function, uint32_t line, uint32_t error_number ) { /* Fatal Error, so initialise the minimum, inform the user, go to sleep */ vTaskSuspendAll(); for ( uint...

Re: uart_param_config() returns an error

Thanks and understood.
It seems that the routine checks the field rx_flow_ctrl_thresh even when flow_ctrl is set to UART_HW_FLOWCTRL_DISABLE!
And therefore generates the error.
