NHD‐2.8‐25664UMY3 Multifont SPI
« on: June 02, 2015, 11:06:09 AM »
I am using one of these displays with a PIC18F47J13 processor. Everything is working fine except for 1 thing. When I connect to the SPI interface to get a character bitmap, it only works reliably if I insert a 1 second delay before each request. If I reduce this delay it becomes increasingly unreliable until it reaches a point where it simply does not return any data.  I have an EEPROM also working on the SPI which works perfectly, so I am reasonably confident that the PIC side of things is OK.

Any suggestions?

Thanks in advance.

Kev.
