Promlems with ST7920 in fast parallel mode #130

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

1. connect ST7920 (8bit parallel interface) to arduino mega2560
2. draw some graphics

What is the expected output? What do you see instead?
Graphics shows but with a lot of artifacts. Adding a little delay (4-5 us) in 
the end of the method "u8g_com_arduino_fast_parallel_write" helps to fix it.

What version of the product are you using? On what operating system?
