with gLCD_ST7565R_SPI1 only half of the display can be written

[Pascal_2016]

Hello

I want to display text and graphics on my display.

I use the following component:

1. an Arduino UNO
2. a graphic display with the ST7565 SPI controllers
3. the flowcode component "gLCD_ST7565R_SPI1".

When I clear the screen, only half the screen is cleared. I can only display the text in one half of the screen. The other half of the screen shows pixel snow.

What do I have to do to write and draw across the entire screen?

Has anyone had a similar problem with the ST7565 or can someone help me solve it?

Hello,

Have you checked the component pixel dimensions are correct for your display.

If these are correct then maybe try swapping the horizontal and vertical dims and see if this makes any difference.

Hello, Benj,

unfortunately, the display size has been set to inactive and is only half the height. I can't adjust the height of the display with that.

Sorry, unfortunately an error message was displayed twice which made me believe that no reply was sent.

Hello,

Do you have a link or datasheet for your display and I will investigate for you. Just want to check they are not doing anything strange like combining two driver chips together onto one display.

Hello Benj,

Enclosed the datasheet and a screen shot of the attributes of the "gLCD_ST7565R_SPI1".

sorry the attachment was not taken along because of error message from the tool

Hello,

Sorry I'm having technical difficulties with my PC at the moment, here's an updated component you can try which now has editable pixel dimension properties.

Simply copy the file into your "C:\ProgramData\MatrixTSL\FlowcodeV8\Components" folder.
