Post #3732276

I want to build a fast TDC (TimeToDigital) converter with the #RP2350 using the PIOs. Turns out this is reasonably simple by doing wait 1 pin 2 mov y timeout_value waitloop: jmp pin hitreceived jmp y-- waitloop ... The downside is that it takes two clock cycles for each count in the y register. But I want a really fast TDC (2ns resolution with a 500MHz clock). Anyone got an idea how to do faster count + capture on this chip?
