Four UARTs ports are provided for terminal and logging functions using a UART-over-USB transceiver. When the USB micro-B connector (J6) of the EVM is connected to a Host-PC using supplied USB cable (Type-A to Micro-B), the computer can establish Virtual Com Ports which can be used with any terminal emulation application. Virtual Com Port drivers for the transceiver (FT4232HL) can be obtained from FTDI Chip.
Depending on the other Host-PC resources available, the Virtual COM Ports are not located at COM1-4. However, the ports remain in the same numerical order.
Processor UART | Host-PC COM Port |
---|---|
WKUP_UART0 | COM 1 |
MCU_UART0 | COM 2 |
UART0 | COM 3 |
UART5 | COM 4 |
The circuit is powered through BUS power, therefore the COM connection is not lost when the EVM power is removed. An LED [LD1] is used to indicate an active COM connection with Host-PC.
