I want to work VGA output.
HSYNC/VSYNC is working.
But Color-Signal not working.
I check SDA7123(LCD to VGA).
PSAVE signal is 1.1V. (not 3.3V)
I tryed.
PMUGPIO0_c1 is enabled.
GOIO0_C1 set to ‘1’.
How do I ?
Additional,
I was done following.

I was resolved myself.
I did not set GPIO direction and GPIO output.
I did miss-coding.
(And little mistake)
I was modified my-code, VGA-output OK!!
