Hello!
I am using LPC2138, i have interfaced the OSRAM OLED (128 x 64) with parallel data bus i.e not using i2c interface of data communication.
the harware is OK. all the voltage levels are fine , Data is arriving on the connector OK. But the OLED is not responding.
I first interfaced the OLED with AT2051 MCU, and it worked fine there.
Please help me in this matter. Thank you in advance.
"i think (sic) there are no other functions/code specific for 2051"
You only think? It's your code - you should know
Time to check and be sure, then!
Have you checked at the interface pins that everything - especially timing - is correct? Have you double-checked it against the display's Datasheet?
It is possible that your 2051 code was marginal, and really only works by luck - your luck ran out with the move to the LPC...
