Hello, I am transferring a ESP32 WROOM code to a C3. I updated all the pins to my new configuration (missed a few the first time) but when the C3 tries to boot, it gets stuck in a booting loop (see below). I did some research, and it looks like this is likely a pin mapping...

根据SoftwareSerial库,esp23c3的有效pin如下:return (pin >= 0 && pin <= 1) || (pin >= 3 && pin <= 7) || (pin >= 18 && pin <= 21); 共九个,每个软串口用2pin,故建4个软串口也就是极限了。 测试程序: 1#include <SoftwareSerial.h>2SoftwareSerial uart1(4,5);//RX=d5,TX=d63...

Re: ESP32-C3-MINI-1 doesn't boot up or print any UART when resetby ESP_Sprite » Fri Nov 15, 2024 7:59 am Yeah, that's likely an issue with either the power supply or the EN pin logic. It should pull more current than that when it's active....
