High-speed data communication is possible by using the DMA for multi-buffer configuration. It also supports the LIN (local interconnection network), Smartcard Protocol and IrDA (infrared data association) SIR ENDEC specifications, and modem operations (CTS/RTS). It supports synchronous one-way communication and half-duplex single-wire communication. The USART offers a very wide range of baud rates using a fractional baud rate generator. The universal synchronous asynchronous receiver transmitter (USART) offers a flexible means of full-duplex data exchange with external equipment requiring an industry-standard NRZ (Non-Return-To-Zero) asynchronous serial data format. Check this in-depth tutorial for more information about UART serial communication, how it works, and much more There is no incoming serial clock signal, so in order to achieve proper communication between the two ends, both of them must be using the same baud rate. On the other hand, the Asynchronous type of transmitter generates the data clock internally. The Synchronous type of transmitters generates the data clock and sends it to the receiver which works accordingly in a synchronized manner. USART – Universal Synchronous/Asynchronous Receiver/Transmitter.UART – Universal Asynchronous Receiver/Transmitter.There are actually two forms of UART hardware as follows: In this tutorial, we’re actually concerned with the internal UART module within STM32 Microcontrollers. UART is sold/shipped as a standalone integrated circuit ( IC) or as an internal module within microcontrollers. Universal Asynchronous Receiver/Transmitter or UART for short represents the hardware circuitry (module) being used for serial communication. Next, we’ll do a couple of LABs to practice using USART in different projects for communication or even debugging. And that’s it for this theoretical tutorial. In conclusion, we’ll take a look at the possible interrupt signals that can be triggered by the USART hardware. And we’ll get a closer look at the STM32 USART hardware module and its internal functionalities, modes of operation, options, and configurations. Starting with an introduction to UART serial communication. In this tutorial, we’ll be discussing the USART / UART hardware in STM32 microcontrollers. STM32CubeIDE also includes standard and advanced debugging features including views of CPU core registers, memories, and peripheral registers, as well as live variable watch, Serial Wire Viewer interface, or fault analyzer.Previous Tutorial Tutorial 9 Next Tutorial STM32 USART / UART Communication Tutorial STM32 Course Home Page □ STM32CubeIDE includes build and stack analyzers that provide the user with useful information about project status and memory requirements. At any time during the development, the user can return to the initialization and configuration of the peripherals or middleware and regenerate the initialization code with no impact on the user code. After the selection of an empty STM32 MCU or MPU, or preconfigured microcontroller or microprocessor from the selection of a board or the selection of an example, the project is created and initialization code generated. STM32CubeIDE integrates STM32 configuration and project creation functionalities from STM32CubeMX to offer all-in-one tool experience and save installation and development time. It allows the integration of the hundreds of existing plugins that complete the features of the Eclipse ® IDE. It is based on the Eclipse ®/CDT™ framework and GCC toolchain for the development, and GDB for the debugging. STM32CubeIDE is an advanced C/C++ development platform with peripheral configuration, code generation, code compilation, and debug features for STM32 microcontrollers and microprocessors.
