In this tutorial we create a bidirectional SPI interface. A regular SPI interface receives a word for every word it transmits. So, we need two AXI stream interfaces. One slave and one master. This tutorial will be less verbose than the others showing only screenshots of the most notable items. […]

Want to probe signals? Just use the built-in logic tester. OK. It’s not quite a replacement for a real logic tester. But it is immensely useful. For debugging purposes, you can add Debug Cores to the FPGA which record digital signals into on-chip memory (probably block RAM). You can use […]
In the previous post we learned how to create an SPI transmitter with an AXI Stream interface. Now let’s use it in a block diagram. And write some C-Code to drive it. We will not hook up real hardware to the SPI as this is just for demonstration. In this […]
