Redpitaya Forum

Hello,

I just bought a STEMLab 125-10 and am new to FPGA so please excuse me if this are dumb questions. I recently downloaded the board and constraint files from github. Vivado identifies the board files as a STEMab-14. Secondly, I imported the .xdc files from the examples (Led Blinker/Frequency Counter) and noticed that the ADC inputs are 14-bits but my board is obviously 10-bit. Do I need to change this?

Please let me know if these questions aren't clear.

Thanks,

Chris

Hi Chris,

Red Pitaya 125-10 and 125-14 (on Zynq 7010) are the same as far as FPGA is concerned.
The only difference is that the 4 LSB pins are connected to ground; therefore the constraint files are valid for both models.

EDIT: please post such questions under the new "FPGA related questions" subforum so it's easier for me to find them in the future.
