Links to useful repos and code for working with Arduino IDE I2C scanner for Raspberry Pi Pico: https://github.com/lkoepsel/I2C/tree/main/Arduino/Pico/I2C_Scanner
Scan SPI Ports on PICO void setup() { Serial.begin(115200); }
void loop() {
Serial.print("MOSI: ");
Serial.println(MOSI);
Serial.print("MISO: ");
Serial.println(MISO);
Serial.print(" SCK: ");
Serial.println(SCK);
Serial.print(" SS: ");
Serial.println(SS);
Serial.println();
delay(5000);
}

Link to earlephilhower skeetch to test SPI. Needed to check how to properly change SPI ports https://github.com/earlephilhower/arduino-pico/tree/master/libraries/SPISlave/examples/SPItoMyself
