Serial Communication¶

Polling Mode¶

A program can await incoming bytes from the serial as follows:

input byte SERIAL;
var byte c = await SERIAL;

The macro CEU_ARDUINO_SERIAL_SPEED specifies the data transmission speed (it defaults to 9600).

In the polling mode, writing to the serial is the same as in Arduino:

Note that variable and function names from Arduino must be prefixed with an underscore to be used from Céu (e.g., _Serial.write()).

Interrupt Mode¶
