Summary
In this chapter, we’ve looked at two more serial interfaces commonly used among hobbyists and in industry, namely the UART and SPI. We’ve developed IP, simulated the UART, and tested both IPs on the board. We’ve also looked at the PMOD interface, and hopefully, you’ve checked out the Digilent website and come up with different ideas for projects using readily available components and IP.
Although we’ll use a Xilinx IP, the UART will become an important interface for us when we look at the Microblaze in the next chapter.
