ST7565R

[saakis]

Hi Matrix people!
I'm trying to compile the flowcode having the ST7565R GLCD in SPI mode but I have error return! If I compile it as parallel it is fine... Is anybody in the forum has any experience with this GLCD to help me? I want to use the GMG12864-06D GLCD but also fails connected it in parallel mode.
Regards

Hello,

Can you attach the generaed .msg.txt file that's generated when you get the error and also attach the project file and we will investigate for you.

Hi Sakis,

Looks like you're out of RAM there, your chip only has 768 bytes of RAM and the component wants 1024 Bytes to function.

Any chance you can use a more modern pin compatible chip with more available RAM.

Thank you Ben!
I will give a try !
Best regards
Sakis
