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

But i got this FTDI adapter with a CTS pin only, is CTS the same as RTS?
Or can i use ...

Greetings!

So i got this plain ESP-WROOM-32 (Not the NodeMCU like Dev-Board with cp2102 included)

Soldered it, connected it to my (separate) cp2102, now it's up and running.
Using picocom i see:

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 ...

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 ...
