Re: Reassign SPI CS1 Pin?

Thanks again for the earlier reply. I was wondering, out of curiosity, why bother exposing GPIO26 externally if it cannot be used as a GPIO?

If there is anything I can do to salvage the existing boards as is, and use the GPIO26 by reconfiguring the ESP32 in software, I would welcome any advice ...

Re: Reassign SPI CS1 Pin?

Thank you for the quick response. Sounds like there is no software fix and we will have to solder in a jumper wire to a different GPIO.

Reassign SPI CS1 Pin?

Hi - We made the mistake in our PCB design of using GPIO-26 on an ESP32-S2-Wrover-1 module to drive a motor controller input and only realized too late that GPIO-26 is a reserved pin on the ESP32-S2.

The ESP32-S2 datasheet (p. 11)
