pub const M5_ST7789V2_INIT: &[InitStep];Expand description
Power, voltage and gamma settings for the ST7789V2 panels M5Stack ships
(Cardputer, StickC Plus family). Values are from M5GFX’s Panel_ST7789
(MIT, © M5Stack); porch and frame-rate registers are left at reset
defaults, as M5GFX does, because they differ between panel lots.
