AN50989 - PSoC® 1 - USB To SPI Bridge using PSoC 1

2020 年 6 月 26 日

The discussion includes a brief introduction to the PSoC USB subsystem, the USBFS user module, USB device descriptors and the PSoC SPI user module. It also covers the USB to SPI conversion process with the help of a flow chart.

In addition, a GUI based PC application and an SPI master and SPI slave demonstration project are included in this application note. These two projects serve as example systems and allow a complete demonstration of the bridge. The GUI works only on systems with Windows XP.
