Pinout
With RTL on the iCE40
The wafer names IOB_6a
, IOT_8b
… as well as the pin number ICE_2
, ICE_3
, ICE_4
… can be used from the RTL by picking them from this PCF file.
For Amaranth, until this gets upstreamed, the various board resources including its pins are defined on pico_ice.py
.
With code on the RP2040
The FPGA pins and other signals are defined in pico_ice.h
.
The PMOD pins can also be accessed from pmod.h
and ice_pmod.h
.
