RFID Board & ECIO40
Posted: Wed Jan 13, 2010 12:40 pm
I am trying to use a RFID board together with a ECIO40 module but I am having some problems.
It seams as if the serial communication between tyhe modules is the problem.
I have tried the RFID board with a 16F877A running with a 19.6608 crystal and my code works on that setup.
But using the same code with the ECIO40 I can't get a stus of 134 when the RFID is red for instance. All i get is ether 0 or 255.
Is there a problem that the ECIO40 is running at a different clock speed?
Is there a fix for this?
