I want to use PmodIOXP to allow both PmodAQS and PmodHYGRO to be connected into the same port in Zybo Z720. However, I do not know how to write my block design in Vivado since there is no IP for PmodIOXP in the vivado-library. Also, what kind of C++ code should I write in my Vitis after I exported my vivado file into Vitis
