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.
The commands are the same as for 2051. However I have changed the port mappings and i think there are no other functions/code specific for 2051
"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...
