Hi there,I have created Analog Digital Converter (ADC) as custom component interfacing with Nios ii using Altera Monitor Program. I am using Terasic DE0-Nano Cyclone IV. The ADC model is NS ADC128S022, 8-Channel, 12-bit A/D Converter, 50 Ksps to 200 Ksps. On the terminal at Altera Monitor Program, I can see the converted values of the eight channels. Forgive me that I am really new to hardware world... What I want to do is to verify that my ADC is giving the correct result, how could I achieve this using Altera Monitor Program? If the above is not possible, I am wondering how to use RS232 UART to verify that my ADC is giving the correct result? Any resources or links would be appreciated as I can say that I know nothing about how to perform this using RS232 UART.

--- Quote Start --- To verify it is correct, you will need to measure voltage levels on the board, to check against the expected values in your FPGA. --- Quote End --- Tricky, thanks for your reply... How could I use RS232 UART to send data to my ADC and to show the converted value on the screen in order to verify the results? I know I am blur on this, very bad understanding in hardware, forgive me I think my question is how can I use RS232 UART to verify the results (converted digital outputs match the analog inputs)?
