Just starting to put together my carputer and this is awesome !
I have an 8 sensor (4 front + 4 rear) parking assist unit in my car and it seems to be a similar model to your first system in the first post of this thread going by the case markings. It is a wired display and similar to the following unit on ebay 8-sensor parking display.
My question is...
If I do a scope trace of the signals it uses, could you do a custom PIC for me which does the full front+rear in the one interface ?
