Re: How to use LEDC PWM in low speed mode?

The low-speed timers l_timerx on the low-speed channel differ from the high-speed timers h_timerx in two aspects: 1. Where the high-speed timer clock source can be clocked from REF_TICK or APB_CLK, the low speed timers are sourced from either REF_TICK or SLOW_CLOCK. The SLOW_CLOCK source can be eit...

Re: How to use LEDC PWM in low speed mode?

Not sure if the driver doesn't support all 16 channels... they may just not be supporting the low-speed option of the low-speed channels. But anyway, if you want to poke at the registers yourself, the LED PWM controller is documented in the TRM: https://espressif.com/en/content/esp32-technical-refe...

Re: Low Rate WIFI Protocol LR

@Rudi: my long range test didn't go well because of a mechanical problem on the test vehicle (motor support plate fell apart). Will try again when I figure out how to 3d print a new one... @ivan txs, - (would help you on 3d print, but have not started this theme - but next time i do this too ) best...

Re: Command line sample code to accept custom command as input

Hi, Please let me know if anyone has implemented such kind of command line code which will ask for input and will perform operation for WiFi or UART or other interface test-cases based on input. As I have checked with scanf function but some how its not working as not able to stop execution process...
