tera term for two pmods

Question

Hello,

Does anyone know if I can have two pmods showing in tera term? I had two ad2 pmods connected to my ja port and one to my jd port in my fpga board and I want to see what both are showing in tera term, but when I open tera term only one of them shows.

Any suggestions would be helpful. Thank you.

Hello,

The PmodAD2 communicates over I2C protocol with the main board on which the Pmod is plugged. The PmodAD2 has no UART / USB capabilities.

It is the main board that communicates - using its USB-UART capability - with the PC. Connecting the board using a USB cable creates a COM port on the PC. When you open a TeraTerm (or other terminal) connection, you select the COM port.

Therefore a possible approach could be to have 2 PmodAD2 connected to a single main board, in different Pmod connectors. The SDK application should gather the AD2 data (measurements), format a text message containing these measurements, and then sending the text message over UART to the PC, to be later visualized in a terminal.

What application are you running on the FPGA board ? You should modify it to read the other Pmod as well.
