DAP_UART_Transport

Set UART transport mode.

DAP_UART_Transport (0x1F):

Sets the UART transport mode for receiving and transmitting data.

DAP_UART_Transport Request:

| BYTE | BYTE      |
> 0x1F | Transport |
|******|***********|

• Transport:
  • 0 - None (default, if transport via USB COM Port is not implemented).
  • 1 - Transport data via USB COM Port (default, if implemented).
  • 2 - Transport data via DAP commands.

Note

By default, data is transported via the USB COM Port (if implemented). In this case, the UART is controlled via a terminal (for example Putty), which can configure the UART (data bits, party, baudrate ...) and transfer the data.

When transport data via DAP is enabled, CMSIS-DAP takes control over the UART with commands: DAP_UART_Configure, DAP_UART_Control, DAP_UART_Status and DAP_UART_Transfer.

DAP_UART_Transport Response:
