I figured it out. #include <stdio.h> #include "driver/ledc.h" #include "esp_err.h" static void ledc_init(void) { ledc_timer_config_t ledc_timer = {}; ledc_timer.speed_mode = LEDC_HIGH_SPEED_MODE; ledc_timer.timer_num = LEDC_TIMER_0; ledc_timer.duty_resolution = LEDC_TIMER_1_BIT; ledc_timer.freq_hz =...

What is some code I can use to output the master clock frequency to CLK_OUT(0) pin which is GPIO0? I am not able to find it in the programming guide, only info concerning EMAC_CLK_OUT. I want to use GPIO0 because I already have my boot mode button there and I can just probe that to get the signal as...

In the schematic for ESP32-D0WD and ESP32-D0WDQ6, there are capacitors on pins 43 and 46 and both are connected to 3.3V power rail. Cap C20 value is 1uF and C3 is 100pF, but it doesn't specify which capacitance value should be at which pin. Is there any advantage to having either value on a specific...

My intuition tells me that it probably matters much. Good call on using an 10V ceramic, though, as ceramics loose a lot of capacity when used close to their voltage rating. If you're worried about the ESR of the tantalum, I'd just add a small (1uF) ceramic next to it; WiFi power use tends to be mos...

To be clear, this would be replacing the 10uf C13 capacitor in the datasheet section 2.1, and will be placed as close to the chip as possible behind the other components. https://www.espressif.com/sites/default ... es_en.pdf

I am designing a PCB using the ESP32-D0WDQ6, which will be running the Wi-Fi pretty much full-time. I'm trying to decide on the bulk capacitor for the chip, would it be preferable to use a: 100uf 1210 XR5 10V MLCC: https://www.digikey.com/product-detail/en/samsung-electro-mechanics/CL32A107MPVNNNE/1...
