This library does not yet support the Scenix SX18 and SX28 targets.
This library provides busy-waiting serial asynchronous send and receive routines.
The library first includes serialp which contains the IO pin assignment, baudrate setting and polarity. A local copy of this file can be adapted to accomodate a different IO pin assignment and communication settings.
The provided routines are:
asynch_send( byte in x )
var byte volatile asynch
asynch_receive( byte out x )
asynch_poll( byte out x ) return bit
A call to asynch_send sends the byte x on the serial line.
Assigning to asynch has the same effect as an asynch_send call.
A call to asynch_receive returns with a received byte in x. The call waits untill a byte is received.
A call to asynch_poll returns with a received byte in x. The call returns quickly when no byte can be received. The function result indicates whether a byte was received.
