Hi all,
due to the possibility of colour mapping "any" colour of interest I'll take another look at the PicoHDMI version - BUT NOT the USB variant, since
there is a major flaw in the USB keyboard response time I can not live with. I am exremely happy with the "Converter-Solution" by the user "NoOne",
this allows PS/2 and USB at the same time. I have no interest in gamepads, so I don't care.
Why not the "reference design"? It just don't fit my needs and uses ICs (USB HUB etc.) I don't want on my PCB. And if I see it correctly there is
no free ADC pin at all (used by the SD CARD).
But I need some advide for the best pinout or any problems I might oversee!
This is my Pinout idea:
Are there any problems (conflicts) so far?
With this design I still have 5 pins free
GP26 (ADC!!)
GP20
GP21
GP0
GP1
since GP20 & GP21 can do COM2 & give me a second I2C + PWM
and GP0 & GP1 can do COM1, I am quite happy with it.
The design will be open for anybody when it is done. Like always.
Greetings
Daniel
