ESP32 C3 DEVKIT and SPI

Postby BerndB_ESP32 » Mon Jan 09, 2023 8:02 am

Hi,
I'm just working with the ESP32 C3 DEVKIT but I can't find the right ports
for MOSI, MISO, SCK and SS on the devboard!

Thank you for any help,
Bernd

You can configure any (not otherwise used) GPIO for these signals.

Thank you for your quick answer,
but in my example code there are only 2 GPIO's
#define SS_PIN 5
#define RST_PIN 0

How to handle MISO & MOSI???

Hard to tell without seeing the rest of your code. It also depends on the SDK you're using (ESP-IDF, Arduino, ...)

Here is the solution:
Serial.begin(115200);
Serial.print("MOSI: ");
Serial.println(MOSI);
Serial.print("MISO: ");
Serial.println(MISO);
Serial.print("SCK: ");
Serial.println(SCK);
Serial.print("SS: ");
Serial.println(SS);
