This demo interfaces the Raspberry Pi SPI driver to the SSPI embedded programming source code in the Lattice Radiant™ and Diamond™ software directories. This embedded computing platform provides several benefits, including low power consumption and reasonable performance in terms of CPU, GPU, and memory. This design is applicable to Lattice devices including MachXO2™, MachXO3™, CrossLink™, CrossLinkPlus™, and Nexus™-based FPGA devices.
