RA8835 Initialisation for a beginner
Does anyone have any example code for the RA8835 Graphics LCD. I'm running MPLAB X V5.30 with XC8 V2.31. I am using a PIC18f46K80. I have been experimenting with the above screen for several days now, but without success.The First problem was as follows. For some bizarre reason the pic would initially only output to one port. For example, I was using Port B as the control port and Port D as the Databus. I could control these ports individually and they worked correctly (in different programs).
When I tried to control both ports from within the same program one or both ports wouldn't work. Has anyone come across this before? I have classified this as defective/blown pics. I would appreciate someone elses opinion on this.
I am now using the pic18f46k80, and the program appears to work correctly as programmed. Alas however, the screen remains blank. The code that I am using, has come from the manufacturers after exchanging a number of emails. I have adapted the 8051 code (I think its for the 8051 but no 100% sure) for the xc8 compiler. I don't need anthing fancy I just want to write text to the screen.
I am willing to upload their / my code but be warned its very simplistic and is uncommented, should anyone want to see it.
Thankyou all for reading.
