struct

Member	Type	Description
`hor_res`	`uint16_t`	active display width
`ver_res`	`uint16_t`	active display height
`hcycle`	`uint16_t`	total number of clocks per line, incl front/back porch
`hoffset`	`uint16_t`	start of active line
`hsync0`	`uint16_t`	start of horizontal sync pulse
`hsync1`	`uint16_t`	end of horizontal sync pulse
`vcycle`	`uint16_t`	total number of lines per screen, including pre/post
`voffset`	`uint16_t`	start of active screen
`vsync0`	`uint16_t`	start of vertical sync pulse
`vsync1`	`uint16_t`	end of vertical sync pulse
`swizzle`	`uint8_t`	FT8xx output to LCD - pin order
`pclkpol`	`uint8_t`	LCD data is clocked in on this PCLK edge
`cspread`	`uint8_t`	helps with noise, when set to 1 fewer signals are changed simultaneously, reset-default: 1
