Hi all,

I'm trying to get an ST7529 lcd controller to operate, i'm using it in 8bit (8080) parallel mode, I can read and write to/from the display without problem. But I can get nothing to be displayed, I'm using it in 3b3p mode.

VLCD seems to stay at 14.5 volts regardless what I do with the contrast/boost freq setting, V0 always seems to be low at 5.5v.
I have tried an external VLCD supply with no success either.

Does anyone have example init code, I have used the code in the datasheet so far.

Regards,
Dave

To answer my own question, x6 does not appear to work, going to x7 does however.
