Display stays "off" (SPI)

Display stays "off" (SPI)


I've set up the hardware properly, sticking strictly to the proposal of ELECTRONIC ASSEMBLY's data sheet. I also followed the initial code. The display remains blank and I can't see anything. Please help.


Thank you for your mail. It's quiet hard to guess why you don't see anything on the display. Please double check the hardware: Is the pin numbering correct? Please keep an eye on soldering joints. Another common problem is the SPI Mode. Please use an oscilloscope to monitor the SPI signals and compare to this scheme:


We hope the problem could be solved. If you have further questions, please contact us.

You do find more information and programming examples at  "Application Note and Arduino"
