I received a request for a port of the graphics routines for the DOGM128 LCD display which uses the ST7565R controller.

So here it is

Pinout for CD (marked A0 on datasheet), CS, and RESET can be set in Basic. Pinout for the SPICLK and SPIOUT are of course fixed.

The Cfunctions are identical to the OLED and NOKIA SPI displays.

Hi Peter,

From memory, these modules have an option for a touch overlay (resistive). Is there any existing 'matherp' code that you think is available to work with a suitable touch controller that the touch overlay is compatible with?

Thanks.

I didn't see a touch overlay on RS when I bought the display and backlight so can't comment. The 2046 touch controllers are available from a number of manufacturers and seem to be ubiquitous so should work with any "raw" resistive overlay

I tried this with a Zolen ZLE12864B which is similar to the DogM128. The ZLE12864B uses the ST7565P controller rather than the "R" version. It ran but the contrast was poor and the screen lost the 8 left bits so when the Hello World screen came up I saw ello World. The ZLE12864B may require a few tweaks to the code to get it working.Edited by micronut 2015-02-05

A couple of years ago I played with a touch screen. It uses the resistive screen without any controller IC.

The code is for a colour maximite and is old by today's standards but should be easy to get up to date.

You might need a series resistor to keep the current draw down.

Thanks Jim for the link.

If I find time in my forever shorter days, I will have a play with the code . . .
