Post subject:  set/reset (1)pixel for T6963c LCD display need help
Hi all,

I am a new member. I need help on set/reset pixel for T6963c.
I have been trying to do it for a week, but i always end up with setting 8 pixels/time. Could any one please explain to me how to set/reset the pixel?
Thank you,

I'm guessing that you might not be able to.... I'm guessing that what you might need to do, is read the byte location into memory, change the bit you want to change, and then re-write that back.

But I'm only guessing, so I could be wrong.

With T6963C controller this is possible without reading back the data.

Check the SetLCDPixel() and ClearLCDPixel() functions here:

Can it be done in asm? I am having difficulties trying to convert the SetLCDPixel() to asm.

addr = G_BASE + (y*BYTES_PER_ROW) + (x/6);
WriteData(addr & 0xFF);
WriteData(addr >> 8);
WriteCtrl(0x24);
WriteCtrl(0xf8 | (5-(x % 6)));

MOV COM,#98H
LCALL C_DW2
MOV DAT1,O_X
MOV DAT2,O_Y
MOV COM,#024H
LCALL C_DW
MOV COM,#0F8H ; SET DATA AUTO WRITE
LCALL C_DW2

Have I done the conversion correctly? I think I had left out something because my display was not too ideal.
