GPIO 9 doesnt work as OUPUT
Posted: Sun Jun 05, 2022 2:18 pm
Greetings!
I am very new to all this.
I am building a LoRa telemetry project based around the ESP32-C3FH , and this is something I came accros.
I am using SPI to talk to an RFM95W and I am using GPIO 9 as a SS/CS pin. To use it as a SS pin I need to set the pinMode to OUTPUT instead of the standard INPUT_PULLUP.
I am using the internal flash on the ESP32C3FH and flash mode DIO.

(Internal Weak Pullup used)
gives me this ERROR:
Is there something with GPIO9 that I missed?
I tried this on GPIO10, and there it worked flawlessly.
Kind Regards!
