Hi guys! It must be some stupid mistake! But I can't find it!... So the following program supposed to send sawtooth signal to DAC1 and sine wave to DAC2 via DMA. But I have sine wave on BOTH pins GPIO25 and GPIO26! (ESP32 Wemos LoLin32 with ESP32-D0WD CPU) Appreciate for any help!!!! #include "drive...

I have to figure out this issue! I have changed sd card adapter from this one with no regulator and buffers: https://ae01.alicdn.com/kf/Ha6ab7d4647004bc0a6e29375dbe1b6b6L.jpg to that one with reculater and buffer: https://3v3.com.ua/data/medium/microsd_module.jpg Additionaly I tried to shortcut AMS1...

Hi guys! Please help if any chanse... I have stuck with the strange problem... I am prototyping an simple board based on TTGO esp32 board... OLED had started instantly. But SD card inited, correct detected, returns right size and free space... but there is no chans to open for reading or writing fil...
