Hi folks,
Has anyone implemented an RS232 serial control interface in the FPGA. I have an application for which I need to transfer large amounts of data to the PC, and control information back. The target device (the one I am connecting to the XEM) has a parallel data output and an RS232 control, much like a digital output surveillance camera.
Any thoughts on this would be appreciated.
Thanks,
Vivek
Hi Vivek-
We have done such designs for clients. In our designs, the full UART functionality is not required because the device operates at a fixed baud rate. This makes things somewhat easier. We used a core generator FIFO to buffer the input / output and had a simple state machine for each rx and tx side of the interface.
Since these were done for clients, the implemenations are confidential, unfortunately.
