Re: ESP_LOG giving a panic error

Code: Select all

xTaskCreate(&blink_task, "blink_task", configMINIMAL_STACK_SIZE, NULL, 1, NULL);
Try increasing your stack size (e.g. 4096).

Re: freeRTOS / Default Events/Tasks Clarification please....

Can someone give me a point in the right direction on the documentation that explains how and where the initial default tasks are being started -- and the where the scheduler is being started in a default sample project? An application's entry point is the app_main() function which is run from a ma...

Re: Timer divider and frequency

Does it mean I can have the timer ticking at 40MHz? Yep, just set the divider to 2 Except 0 (obviously), but also 1. Why can it not be 1? Because of the division operation or some other cost involved in prescaling the clock? It's a hardware limitation. A Timer's internal logic operates according to...

Please check if you have properly defined your IOT_SOLUTION_PATH via the following command:

Code: Select all

printenv IOT_SOLUTION_PATH
If not, please set your IOT_SOLUTION_PATH according to the instructions stated here.

Re: Software Timer using xTimerCreate runs 33% slow

Some points to consider How are you actually measuring the duration of your timer? The timer doesn't start until xTimerStart() returns, and xTimerStart() has a possibility of being blocked if the timer's internal command queue is full. The timer callback could be delayed in running if there is some...

Re: Timer divider and frequency

An 80MHz APB Clock is fed into the entire Timer Group. Each timer then takes 80MHz APB clock and divides it down via the prescaler to a frequency of their own liking. How much the 80MHz clock is divided down by is determined by the value set in the prescaler (i.e. the Divider). The divider can take ...

Re: ADC VRef calibration eFuse

Is there an easy way to override the fuse value when calling esp_adc_cal_characterize? No matter what I supply for the VREF param it always gets set to 1100 because the fuse takes priority. In esp-idf, the simplest way is to modify the esp_adc_cal_characterize() function directly as such: //Check e...

Re: Can anyone guide me for debugging code on eclipse using WROVER kit

Just to rule out the obvious. Are you able to debug without using eclipse (i.e. running OpenOCD and GDB)?

Re: watchdog timeout triggered by error in ieee80211_output.c

E (59990) wifi: ieee80211_output.c 552 This is simply the last log output before the task watchdog triggered, thus is not necessarily the cause of the task watchdog timeout. Using make menuconfig , please enable the panic on task watchdog timeout option under Component Config->ESP32-Specific->Invok...
