Now it is going to pay off that we are using an AXI interface on our I2S transmitter. We can now exchange the FIFO with a DMA controller. DMA stand for “Direct Memory Access”. The DMA controller can move data from the main memory to the AXI stream interface without […]

The previous tutorial showed how to use an I2S IP core to send audio data to the ADAU1761 codec of the Zedboard. We used a polling loop to keep the FIFO filled. In this tutorial we will connect the interrupt output of the FIFO to the ZYNQ fabric and have […]
Can’t figure out why you can’t use cos, sin or pow functions in a Xilinx SDK project? I found it surprisingly obscure as well. A solution is described here. Here are some screenshots:
In this tutorial we add an I2S transmitter to the design. This enables us to finally generate an audio signal. This tutorial is based on the last post where we already configured the codec. In this tutorial we will learn How to create an I2S interface with a slave AXI […]
