Data transfer via USART.

blockType: CFunction

artery usart tx

Path in the library:

/Interfaces/Targets/Artery/Artery USART TX

Description

To work with the block, install/update the support package. equipment.

Block Artery USART TX used for data transfer via USART. Transmission of both scalar and vector data is supported.

Configuring the AT32 Workbench

  1. In AT32 Workbench enable the desired USART/UART module:

    artery usart tx enable

  2. Configure the parameters in the Basic Parameters tab:

    • Mode — Asynchronous;

    • Baud Rate — required speed;

    • Word Length — 8 Bits;

    • Stop Bits — 1;

    • Parity — None.
