St7920 lcd driver

Hello, it is very useful. Thank you. Just trying to test it, i have some errors and would like to ask if you for a sort of initialization, that could it be missed, as it is mentioned in several examples 'HelloWorld' within U8glib library. For instance in this case:. I want to use this code for arduino mega what changes should I do? Get Our Weekly Newsletter! Helena St. Related Content.

By doing so read-modify-write issues are avoided, which you'll sooner or later stumble across. Ok, next try. Before configuring any pin as an output, the corresponding LAT register bit should be set to the desired value. What's the supply voltage of the LCD? If supplied by 3.

If supplied by 5V, the SPI frequency would be ok, but a high level won't be recognized without using a level shifter minimum input high level is 0. So when CS is low, nothing on the display?? It means that if CS is low, the serial interface is reset serial data byte counter and received data bytes. This doesn't affect the screen content.
