// The Sparkfun MicroMod spec uses a zero-based peripheral numbering scheme.
|
|
// In cases where the 0th peripheral is the default, the "0" is omitted from
|
|
// the name (e.g. "I2C" instead of "I2C0").
|
|
//
|
|
// Note: UART (UART0) is not present in the edge connector pinout because the
|
|
// primary debug serial port is exposed as a virtual serial port over USB,
|
|
// i.e. Serial.print() should print over USB VCP, not UART_TX1.
|
|
