uartCfg - Configure UART¶
Configure a UART port. This command can be used to adjust the baud rate and bit settings of a UART port. Additionally, it can be used to configure additional UART ports via USB.
Usage:
- command: uartCfg <uart_port> <speed> [<triplet>]
[id: <usb_device_id>]
[path: <usb_device_path>]
[interface: <usb_device_interface>]
Argument |
Description |
---|---|
uart_port |
UART port name: |
speed |
Baud rate. |
triplet |
UART configuration triplet: |
usb_device_id |
Optional: USB device identifiers: |
usb_device_path |
Optional: USB device path: |
usb_device_interface |
Optional: USB device interface: |
External USB serial interfaces can be configured as UART ports by using the usb_device_id, usb_device_path, or usb_device_interface fields. FTDI UART adapters and USB-CDC peripherals are supported.
Note
The built-in UART ports cannot be redefined. That is, the usb_device_id, usb_device_path, and/or
usb_device_interface parameters can’t be set on UART0
or UART1
.
Special Test Point Usage on PLT-200A:
- command: uartCfg UART0 tp
On the PLT-200A, use the tp
flag to disable UART0
, and re-use its pins as DATP08
, DATP09
,
DDTP15
, and DDTP16
. This functionality is not available on PLT-300A.
