USB-Serial Configuration
6.2.4 Additional Features of the USB-Serial Device
Apart from the UART and the GPIO features described in earlier sections, the USB-Serial device
included in the CY8CKIT-049-4xxx provides several other features, such as the following:
■ USB-I2C (Master/Slave)
■ USB-SPI (Master/Slave)
■ Cypress CapSense (up to eight buttons)
■ Battery Charging Detect (BCD)
For more information on these features, refer to the device datasheet and the USB-Serial Configura-
tion Utility user guide. (Select Help > Help Topics).
Note: USB-UART works in the USB Communication Device Class (CDC), while all other configura-
tion controls such as GPIO, SPI, and I2C use the Cypress vendor driver on the PC. Therefore, COM
port tools such as PuTTY or HyperTerminal will only work for the UART bridge. You can use the C++
APIs to create scripts and tools included with the USB-Serial SDK to evaluate and control the other
bridge options.
