Hi, is there any update for this issue? I'm still having the same issue as mentioned in the topic (RGB becomes BRG mapping).

Tested with:

  • Arty-Z7-20
  • Vivado & Vitis 2022.2

from vivado-library.

Modifying PmodOLEDrgb.c does fixed my problem though:

@@ -1172,7 +1172,7 @@ u16 OLEDrgb_BuildHSV(u8 hue, u8 sat, u8 val) {
 **      Converts separate RGB values into a 565 RGB value used by the OLEDrgb
 */
 u16 OLEDrgb_BuildRGB(u8 R, u8 G, u8 B) {
-   return ((R >> 3) << 11) | ((G >> 2) << 5) | (B >> 3);
+   return ((B >> 3) << 11) | ((R >> 2) << 5) | (G >> 3);
 }
