1. 請問SPI Node後面 chip select接兩個以上的device, USB-Serial SDK中有support嗎?
因為Cypress提供的CyUSBSerialTestUtility沒看到可以對chip select做選擇.
2. 當 usb後的SPI Node接兩個以上, driver 會建立不同 DeviceNum供選擇對嗎?
Solved! Go to Solution.

Hello,
The Utility or the SDK does not use multiple slave select lines for SPI communication (CY7C65211 as a master). So the SPI slave should be enabled externally using GPIOs (as select lines) and an external MUX if more than one slave device is connected to the master (USB Serial).
Best Regards,
