Description
int
GPIO used to select the D/C line, set this to -1 if the D/C line is not used.
Callback invoked when color data transfer has finished.
void *
User private data, passed directly to on_color_trans_done's user_ctx.
uint8_t
Amount of SPI bit-cycles the cs should be activated before the transmission (0-16).
uint8_t
Amount of SPI bit-cycles the cs should stay active after the transmission (0-16).
