UPGRADING OUR SERIAL LCD PROJECT

摘要

In the previous Primer installment, we took a quick look at several of the new features of the recently released M2 line of PICAXE processors, and then explored two of those features in more depth. First, we experimented with the new timeout option for the serrxd and serin commands which now enables us to specify how long (in milliseconds) an M2 program should wait at a serrxd or serin command before "giving up" and moving on if no data is received. As a result, we no longer need to know exactly how many serial bytes will be received. As long as we provide more than enough variables in which to store the incoming serial data, the new timeout option will enable our program to "move on" to processing the data, no matter how many bytes are actually received.
