Software:
* USB-SPI Classic: The most basic SPI data transmission and reception (supporting slave mode), it is recommended to use it when data processing is not complicated or the data volume is not large.
* USB-SPI Flash Programer: Specifically for reading and writing data to the Flash memory of SPI interface. It is very convenient when writing or reading data to the Flash chip of SPI interface. The software can only be used in the hardware SPI mode (standard mode). And at the same time, you can modify data reading and write start address on the software interface.
* USB-SPI Extend: Data transmission or reading can be pre-edited in a list, and the software can read and write data in accordance with the operation mode of list editing. It is recommended to use this software when more complicated control is required for the SPI interface chip.
