CY7C65211 more SPI device support?

[Mitchell_shen]

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?

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).
