Thanks! I assume this is the part I need to buy? http://www.ti.com/tool/usb-to-gpio The ARTIQ manual doesn't say anything about removing and replacing the J65 jumper, which the kc705 manual talks about (p. 74). Is this unnecessary? Also, are all of the I/O pins on the FMC connectors in HR banks

Re: [ARTIQ] 3.3 V I/O on kc705

To expand, the VADJ rail supplies the output stages for the KC705 I/O banks connected to the FMC connectors, so if you want to drive things using LVCMOS or LVTTL 3.3V logic, you will have to program the VADJ rail to supply the necessary voltage. It’s very straightforward; instructions are on

[ARTIQ] 3.3 V I/O on kc705

Hello, I would like to operate peripherals on the kc705 FMC HPC connector at 3.3 V, both input and output. Can this be achieved by just setting the IOStandard to LVCMOS33 in the fmc_adapter_io list in the gateware? I ask because the kc705 manual states that all the I/O voltage rails are set to
