Code example with PSoC 6, PSoC Creator and 128x64 GLCD (ST7290)

[tanomaru]

Hello, community!

I have a 128x64 pixel graphic LCD panel with a ST7290 controller and I want to connect it to a PSoC 6. I understand that there are voltage levels, but I plan to use logic voltage converters to get around the problem. I plan to use serial communication mode, so that 3 GPIOs should be enough.

I would like to know if anyone has done this before, so that I could get a code example to start off. Anyone?

Thank you very much.

Hi @tanomaru ,

We presently do not have a code example which involves the usage of logic voltage converter. However, you can refer this code example here : https://www.cypress.com/documentation/code-examples/ce223726-psoc-6-tft-display-interface-emwin-grap...  to get started with the flow of the code and interfacing an LCD with PSoC 6.

We have few LCD code examples, developed for PSoC 3, PSoC 4, PSoC 5LP : https://www.cypress.com/documentation/code-examples/ce195291-character-lcd-horizontal-bar-graph-psoc... which you can follow,  for debugging your issues.

You can also refer to the datasheet of ST7290 graphical LCD module for more information : https://components101.com/asset/sites/default/files/component_datasheet/ST7290%20Graphical%20LCD.pdf . Also, can you please elaborate your application more, so that we can help you with the proper solution?

Please let us know in case of further queries.

Best Regards,

Aashita

Thank you for the reply, Aashita. I will read the references you indicated. As for my application, the main purpose at the moment is to exhibit simple debugging/monitoring information using a low priority FreeRTOS task. As I said, I have the GLCD lying around and thought it would be nice to use it. Thanks again.
