tried it and it works. With power management enabled, frequency is now stable as it should be. Due to the lower timer input frequency, i had to reduce the resolution from 10 to 9 bit. #include "esp_err.h" #include "esp_log.h" #include "driver/ledc.h" #include "driver/periph_ctrl.h" #include "soc/led...

Thx, there is
uint32_t tick_sel: 1; /*This bit is used to choose apb_clk or ref_tick for high speed timer. 1'b1:apb_clk 0:ref_tick*/
in the ledc soc struct. However, i have not found a way to influence this via the ledc driver, any hint ?

the problem is still present. It works when i do not enable "Enable dynamic frequency scaling (DFS) at startup" If this option is enabled, the ledc frequency is >99% wrong, it looks like this (half the requested frequency and unstable) PilotWrong.png with disabled "enable "Enable dynamic frequency s...

esp-idf v3.1.1 I'm tying to generate an 1 KHz frequency uning ledc (without fade) and the frequency is not stable. How can i fix this ? SDS00002.png Code is as follows: #define J1772_LEDC_TIMER LEDC_TIMER_0 #define J1772_LEDC_CHANNEL LEDC_CHANNEL_0 #define J1772_LEDC_TIMER_RES LEDC_TIMER_10_BIT #def...

Current master is technically "3.2-dev". Sorry, Tried as follows: Recompiled and flashed using 3.2-dev, had to soft restart 2 times to freeze i2c. Recompiled 3.2-dev with your new "i2c_master_clear_bus", uploaded, did a soft restart and i2c works well. Thanks for the fix. Will your fix be integrate...

tried to update to the current idf from github yesterday (June 23, 2018). After that, i had sporadic timeout retuned by i2c_master_cmd_begin. This always happend after i updated the firmware on my esp and restarted (via reset button or software). If this happens, i2c is dead and the only way to get ...

the stack for emacT seems to be to small (2k). The ethernet sample works but in my software i always got stack overflow. I had to change the stacksize to 3k and it seems to work. I had that problem with git versions from december 2017 up to the latest one Feb 2018. esp-idf/components/ethernet/emac_m...

I'm not sure if it is possible with the ESP32 (using esp-idf): i need to create a 1 KHZ pulse with variable duty cycle, should be easy using ledc. However, i need to measure a voltage (8 bit resolution would be ok) at the high time of the cycle. I could simply connect 2 pins to generate an interrupt...
