Hi
Im reparing an old device that have inside a conrad c-control ( year 2004)
The device have a lcd display 16x2 (mc1602E-tgr) i tried many type of lcd of same hd44780 protocol and always give me garbage characters my question is if i can read the code from the device and reprogramm it to print on a another type of display
Pls if u can help me how can i connect this device to a pc and the software needed i think the code language inside is BASIC
Thanks in advance

 

Usually the code inside a microcontroller is protected from being read to keep the propriety code from being copied and stolen by another manufacturer. That means you have to re-create the code from scratch.

 

tok ,thanks for reply
The 16x2 original display mc1602e-tgr when i change it by 1602A give like this garbage characters what is the problem they are the same protocole hd44780

 

Maybe you have some of the D0 to D7 lines swapped.
If you know what the correct text is in your photo of bad text it may be possible to work out which lines are swapped.
