LCD Test

Hi, me AGAIN! I've got hold of an LCD screen (GDM1601C -- Xiamen Ocular) from an old Velleman kit.

Anyway, Could any of you guys give me a quick snippet of code to use to test it actually works? Even if it's just turning all the letters 'A' on or something. Everything I've tried fails .

The "datasheet" for the GDM1601C is here:

Thanks.

Blueprint, give Nigels site a try. It has a good deal of information about PICs and includes LCD tutorials with code.

Hope this helps.

I'm from China.I went to their official site but couldn't find any more info than that.However you may simply write a test routine using this LCD as an external RAM with any MC with parallel port.I will try to find out the driver chip of this LCD so that you can get the exact waveform you want.

Regards

:shock:

Code for what ?

PC LPT/PIC/AVR/TMS/MPS/8051/Zilog ?

anyway read from page 23 https://www.electro-tech-online.com/custompdfs/2005/06/ks0066u.pdf

If you do everything by the book and does not work than your LCD bad ! or just not conected by the book :roll:


It is super easy to make them work, just let me know what you have ?!

just noticed KS0066U in the LCD pdf.Yeah,that's all you need besides the LCD document.
