I am having an LCD issue that is beating me up. I have a project that works with a small LCD display but when I put a larger display on it, it doesn't work. The upper half of the display is 20 solid boxes, and the lower half is blank. I am using the 16F690 MCU and PICBASIC PRO (program sample zipped and attached). The small yet functional LCD Display is a TRULY MCC162B3 16X2 and the larger one is a CRYSTALFONTZ CFAH2002L-YYH-JP 20X2. The CRYSTALFONTZ unit works fine when I duplicate the demonstration in the LCDOUT section of the PBP manual (using a 16F84a). I have checked my connections many times and played with the timing parameters. I am stuck.
Thank you
Dennis
