Description

CMSIS-DAP debug unit can be extended to support a separate UART port that connects to the target. Such a UART communication is typically used for printf-style debugging, but the usage is not limited to that. CMSIS-DAP supports UART communication via:

• dedicated CMSIS-DAP commands: connects seamlessly to (Cloud) IDEs that integrate a printf viewer.
• via standard USB COM port (optional): for any data communication, i.e. to transmit training data sets for machine learning.

The following CMSIS-DAP commands are added to support UART communication:

• DAP_UART_Transport : Set UART transport mode.
• DAP_UART_Configure : Set UART configuration.
• DAP_UART_Control : Control UART data receive and transmit.
• DAP_UART_Status : Get UART status.
• DAP_UART_Transfer : Transfer data via UART.
