Hello All,
I am currently working on getting GPS data from my receiver to the FPGA and displaying the sentences using Eclipse. I have done this in the past using NIOS without any issues, however when I tried to do this again, I am running into garbled sentences. Here are some specifics:- I am using the RS-232 as my serial device input/output
- I have a GPS that runs at 9600 baud with one stop bit, 8 bits of data and no parity
- I have correctly instantiated the RS-232 device within my top level compiled and ran.
- I have generated the NIOS design with the following warning...
- warning: system: "no matching role found for uart_rs232:s1:dataavailable (dataavailable)"
- Eclipse compiles everthing fine, however the data I get back is something like this: >&nÊònÊ2¹NJÒnÊãònÊynÒ>Ê
- The data does come every second as expected

As an addition to my work, I have tried using various baud rates with the same result. I am currently trying to write my own interface and see if that might work. I am using a DE2-115 with Quartus II 11.1.
