I guess there is no documentation on R2 interfaces at the moment. Something equivalent to: https://casper.berkeley.edu/wiki/ROACH_FPGA_Interfaces would be nice. R2's GPIO consists of 16 standard IOs out from the FPGA at a 1.5 IO voltage. There are no bidirectional buffers as there were with R1. Each IO can be input/output/tristate/pullup/pulldown - whatever the FPGA supports. They should be freely assignable. > Also, do pin numbers in the yellow block match the physical layout? They should, file a bug if they aren't. Cheers, David
