Can it be used to use CTS instead of RTS? My FTDI has one DTR, but just CTS.

I read that it is possible for esptool.py to do go into download mode, flash and reset automatically if you connect RTS to EN DTR to IO0 https://github.com/espressif/esptool/wiki/ESP32-Boot-Mode-Selection But i got this FTDI adapter with a CTS pin only, is CTS the same as RTS? Or can i use the CTS p...

Greetings! So i got this plain ESP-WROOM-32 (Not the NodeMCU like Dev-Board with cp2102 included) https://images-na.ssl-images-amazon.com/images/I/81X3aqCrF1L._SL1500_.jpg Soldered it, connected it to my (separate) cp2102, now it's up and running. Using picocom i see: [...] I (28) boot: ESP-IDF v3.0...

Hi,

i've found this: https://www.waveshare.com/uda1380-board.htm
Would that work? Looks good, Line IN Line OUT and MIC IN
It has I2S, but not sure about the MCLK

Moving this to the Arduino subforum. From what I can tell, GPIO1 is the TX pin of your serial port; could it be that your digitalWrite does nothing and the printf actually lights the LED? Can you use a different GPIO? Oh indeed, when i just leave the digitalWrite and no Serial.* it does work as int...

Hi, I opened the default example Blink.ino in Arduino IDE, just added LED_BUILTIN and those Serial.* to see something happening in the console, but the ESP32 LED just flickers everytime it is set to HIGH or LOW. (Serial output is working) I don't get the LED to stay ON... #define LED_BUILTIN 1 // th...
