TTL Input Pin on E1
Posted: Sun Oct 12, 2014 11:06 am
Hi,
I wanted to use a TTL input on one of the E1 pins as a hardware input for one of the pre-existing programs
e.g. a hardware input for the integrator reset for the PID.
Would I have to assign the pin to the PID in the FPGA? Or is it possible to do in the C code/controller?
There seems to be a lot of code in red_pitaya_top.v and red_pitaya_hk.v about the extension connecter for the 16 GPIO pins - is that for future developments and is unused now? If I wanted to specifically allocate one of the 16 pins in the Verilog, could I comment this out?
Thanks for your help
