Is there a way to get analog signals into the Arty XADC using the PMOD connector?

[Meechy]

I see that the analog pinx for the XADC are broken out to A0 to A11 on the Arty A7 board. Is there any way to measure analog signals using the XADC through the PMOD connector or is it only possible with the analog pins on the top of the Arty board?

Hi @Meechy,

Unfortunately you'll be limited to using the Arduino styled header as none of the XADC connections (the CK_A<x> lines and corresponding XADC pins on the FPGA itself on bank 35, see pages 3 and 5 of the Arty A7 schematic, https://digilent.com/reference/_media/programmable-logic/arty-a7/arty-a7-e2-sch.pdf) are routed to any of the Pmod ports (page 1, 4, and 5).

Let me know if you have any questions.

Thanks,
JColvin
