CONFIG_ST7735_GVDD

#define CONFIG_ST7735_GVDD   4800

ST7735 gvdd level.

Default GVDD voltage of 4.8V. GVDD is reference level for the VCOM level and the grayscale voltage level. GVDD should be ≦ (AVDD - 0.5) V .

Definition at line 54 of file st7735.h.

CONFIG_ST7735_VCOMH

#define CONFIG_ST7735_VCOMH   4250

ST7735 VCOMH voltage level.

Default VCOMH voltage of 4.25V. VCOMH represents the high level of VCOM AC voltage. VCOM levels needs to be adjusted to match the capacitance and performance specifications of the TFT panel to maximize contrast and minimize flickering.

CONFIG_ST7735_VCOML

#define CONFIG_ST7735_VCOML   -2000

ST7735 VCOML voltage level.

Default VCOML voltage of -2V. VCOML represents the low level of VCOM AC voltage. VCOM levels needs to be adjusted to match the capacitance and performance specifications of the TFT panel to maximize contrast and minimize flickering
