Device Connectivity
10. Device Connectivity
The SLWSTK6061A provides several convenient ways to communicate with a target application without soldering or using external
hardware.
10.1 Virtual COM Port
When the target device drives the VCOM_ENABLE (PA5) signal high, a communication line to the Board Controller is enabled. The
target can then communicate to the host computer via the Board Controller using USART0, Location 0 (TX pin PA0, RX pin PA1).
When enabling VCOM, the Board Controller makes communication to the host computer possible on the following interfaces:
• Virtual USB serial port using a CDC driver.
• TCP/IP, by connecting to the Wireless STK on port 4901 with a Telnet client.
Note: Only one of these can be used at the same time, meaning that if a socket is connected to port 4901, no data can be sent or
received on the USB COM port.
10.2 Virtual UART
The Virtual UART port outputs data that the target application outputs over SWO, ITM channel 0.
