SPI Storm is Byte Paradigm’s USB Serial Protocol host adapter. SPI Storm supports SPI (Serial Peripheral Interface), 3-wires SPI, dual-SPI, quad-SPI protocols as a master. It also allows the control of custom serial protocol interfaces up to 100 MHz from PC. This white paper introduces the features of SPI Storm and explains why this device can be conveniently used for ASIC, FPGA, SoC and embedded system development, testing and debugging.
