Re: ESP32-C3 SPI Pins as GPIO

SPIHD (GPIO12) and SPIWP (GPIO13) Pins are available to use as GPIO? In the Pin Layout section (2.1) of the datasheet, Pins 19 and 20 (SPIHD and SPIWP) of the ESP32C3-FH4 are labeled as NC (Not Connected). However, in the table in section 2.3, they are designated as default GPIOs. I tested using the...

Re: ESP32-C3 SPI Pins as GPIO

Well, thanks for the support.
I have one more doubt. If using these pins is imposibble. Why does the datasheet mention that using SPI pins as GPIO is not recommended instead of explicitly stating that you can't?
Thanks again.

Re: ESP32-C3 SPI Pins as GPIO

I'am using ESP32-C3FH4. It has in-packge flash. So I don't use an external flash.
Even without external flash there is no way to use them?

ESP32-C3 SPI Pins as GPIO

I have a project with the ESP32-C3 chip, and I need to use the SPI pins (SPICS0, SPICLK, SPIQ, SPID) as GPIOs since I don't have any more available pins. I understand that these are internally connected to the flash. For this reason, if I try to set them through the iomux to function as GPIOs, the M...
