This code describes the Nios SPI nuclear control SD card method, with the most simple way to achieve SD card read/write operations for beginners to understand SD card the operation, including one document describes the process of SD card driver and Verilog code. This code was developed based o...
Prepared in the FPGA configuration through the SPI bus external PLL chip AD9516 program through Board-level debug, validation is available. Programs through a state machine, you will need to configure the register values for the data format sent to SPI bus....
