Re: GPIO output low internal resistor

Not all GPIOs on an ESP32 have pullup and pulldown resistors.
Take a look at the data sheet. All your questions are answered there.

Re: bare PCB with common pinout of Devkit V1

I don't know of a board like that. But why not just remove the IC's off the board you already have.

Re: Where to begin communicating with RS232 ?

If you want to use the UEXT Connector, get the schematic for the board and locate the TX/RX pins used there, and change your #defines for TX/RX pins.

Re: I2C Pins on ESP32-PICO-KIT V4.1

I am not sure what to say here because moving my I2C project from my ESP32-WROOM-32 Dev Kit worked just fine on the Pico Kit using the same pins. Do you have a ESP32-WROOM-32 Dev Kit, that you tried the I2C on first ?

How could anyone possibly answer that without you posting code ?

Re: course in the making

I would like to see how arduino address make menuconfig. It would be interesting to see how Arduino can make changes to these settings.

Re: Voltage drop on EN pin causing reboots

The following scope capture shows the 3V3 rail and the voltage on EN line : (Green = GPIO34 / Yellow = 3V3)
This statement is confusing. Is the scope capture for the green line showing the EN line, or GPIO34 ?

Re: ESP32 OTA Update issue

What I have done which helped me was once OTA has been started, I kill all tasks that I have created. In doing so give full CPU resourced for it to handle the OTA update.
