Red and Blus Color setting wrong in TFT lib

[Sean shao]

Set color to red but shows blue.Set color to blue but shows red. The color green is fine.

Test on M5stickCPlus with IDE Polit 1.1.81.

It could show the right color on the M5Core screen.

M5 switched display hardware for some products, which caused a red/blue swap but I can't remember the details. I will check my M5StickCPlus.

Yep -- turns out that the hardware displays in the M5StickC and the M5StickC+ use different pixel formats: BGR vs. RGB. The fix will be in the next Pilot release. (You'll need to update the MicroBlocks firmware using the new Pilot release when it is available.)
