Code for hire ( Graphic LCD code "ST7565R ")
PostPosted: Tue Jan 25, 2011 5:11 pm     Reply with quote
Hello,

I am planning to use a graphic LCD by newhaven that uses the ST7565R controller. The code library for ST7565R is written in C for AVR so I need help to convert it to CCS and possibly add a big font feature to the code.

Please let me know if you're able to help and how much will you charge?

Here is the open source code: https://github.com/adafruit/ST7565-LCD
Here is the LCD that I am planning to use: http://www.mouser.com/Search/ProductDetail.aspx?qs=jAHslVI6snuT2SwKL81Irw%3D%3D

I am using Pic16F727.

Thanks

Hi,

Did you made any progress? Can you share code with us?

I'm using a PIC16F877-A @ 4MHz "So no need to check the busy flag because the timing is just perfect at such frequency" and the TOPWAY LM13232AFW 132x32 GLCD module. Make sure you check your product datasheet for any changes that you might need.

Hi,

I'm still at the lcd selection process. We need a 3V3 text or graphic display.
