Character LCDs / NHD-0420D3Z-FL-GBW-V3 not displaying cahracters
« on: February 03, 2017, 08:24:14 AM »
I am using a NHD-0420D3Z-FL-GBW-V3 in the SPI mode to interface to an Arduino Uno.  Every time I write to the display, all the pixels in a character are illuminated,  as if is sent FF, rather than the actual 31 (1) that I was using to test my set up.  I have the baud rate set at 9600 (yes, slow I know, but I'm just testing at this point ) , MSBFIRST, and SPIMODE3.   I'm not sure what's going on here, any advice?
