Description

I wanted to use GPIO9 and GPIO10 on the WROOM32EU as UART1. However, after checking some forums, I found out that these pins are used for flash memory in this version, but the official documentation mentions that these two pins can still be used as UART. I tried to implement this in Arduino and it worked, but I couldn't achieve the same with MicroPython. Is there any way to do this?

Implementation

• I intend to implement this feature and would submit a Pull Request if desirable.
• I hope the MicroPython maintainers or community will implement this feature.
• I would like to Sponsor development of this feature.

But the docs also say:

The ESP32 has three hardware UARTs: UART0, UART1 and UART2. They each have default GPIO assigned to them, however depending on your ESP32 variant and board, these pins may conflict with embedded flash, onboard PSRAM or peripherals.

My question would be ... how does Arduino work-around this apparent conflict?

Hello davefes

Right, so I later changed the pin configuration to other GPIOs. Thank you.
