Forum Index : Microcontroller and PC projects : 5" EastRising display

A friend bought three 5" EastRising displays:

https://www.buydisplay.com/display-5-inch-tft-arduino-touch-shield-ssd1963-for-mega-due

I have tested them using both supported 5" drivers on both MM+ and Webmite and they work well, apart from having the red and blue colours reversed. Normally this would not be a problem but the project uses bitmap images. The EastRising 9" displays work perfectly when plugged into the same circuits.

I can hack my way past this by recreating the BMP files with the red and blue bytes swapped but thought I would check here to see if anyone has better suggestions.

I appreciate any suggestions.

It would be nice if you could use "non-Shield" version and swap the R and B pins in the connector or cable...

Yes!!! That makes perfect sense.

Just tried these on my ER 5" on an Armmite F4. POKE DISPLAY command used to change the colour order after the display is configured. Seems to work, should work on picomite. You may be able to put the POKE command in MM.STARTUP

POKE DISPLAY &H36,&H08 Landscape
POKE DISPLAY &H36,&H58 Portrait
POKE DISPLAY &H36,&H38 RLandscape
POKE DISPLAY &H36,&HB8 RPortrait
