    Hi, I have Basys 3 for SPI slave and it supports 3.3 PMOD IO but I have 1.8V SPI Master So I need to have a way to use 1.8V PMOD. I went through the forum and found the level shifter at https://store.digilentinc.com/pmod-lvlshft-logic-level-shifter/ but I need bi-directional level shiter. So I am trying to find out the FPGA board can support 1.8V PMOD. Would you please recommend it? Currently I am seeing Nexys Video has SET_VADJ that can support 1.8V. Can someone please confirm it can support 1.8V PMOD IO? If yes then would you please let me know how to program SET_VADJ to 1.8V?

    Zybo board 1.8V logic

    malkauns posted a question in FPGA

    I have a quick question. I am trying to interface my Zybo board with a camera module (Arducam OV5640). The datasheet says that it uses 1.8/2.8V logic. In my XDC file do I simply use IOSTANDARD LVCMOS18 for each pin? I have tried this using the pmod connectors on the Zybo board and setting one pin high but when I check the voltage with a multimeter it reads 3.3V.
