Two Byte Sender

By Sensor Workshop Class fall 2005

This PicBasic Pro code sends a word variable to an external computer serially. when it receives a single byte of value 65, it sends two bytes of a word variable, high byte (most significant byte) first.

It works well with the Processing Two Byte Receiver example.

' this is a sample to send a word variable to 
' an external computer.  when it receives a single byte
' of value 65, it sends two bytes of a word variable,
' high byte first.

' it uses a call-and-response method, waiting for a byte from 
' the external computer.
