Dear Champs,
Our customer use raster LCD control on our TM4C129x and use raster_displays.c code to refer it.
But met one problem, we do not know why this value is 0 on tRasterDisplayInfo -->sTiming in uint8_t ui8ACBiasLineCount; of tLCDRasterTiming.
const tRasterDisplayInfo g_sOptrex800x480x75Hz =
{
"800x480 at 75Hz on Optrex T-55226D043J-LW-A-AAN",
30000000,
SYSCTL_CFG_VCO_480,
120000000,
{
(RASTER_TIMING_ACTIVE_HIGH_PIXCLK |
RASTER_TIMING_SYNCS_ON_RISING_PIXCLK),
800, 480,
2, 30, 8,
10, 10, 8,
0
},
0
};
Because we could see the timing in datasheet, we see many LCDLP counts before LCDAC set,
And see the register description ACBP in TRM, should we give a value on ui8ACBiasLineCount?
If you have any suggestion or good explanation, please feel free to let me know.
Thanks a lot.
