STM32 is a family of microcontrollers manufactured by STMicroelectronics. The STM32 microcontrollers come with a wide range of features and capabilities, including support for the RS485 communication protocol.
RS485 is a popular communication protocol used in industrial and automation applications. It is a differential communication standard that allows multiple devices to communicate over a long distance using a single communication line. The RS485 protocol is known for its robustness, noise immunity, and high-speed data transfer capability.
The STM32 microcontrollers come with built-in support for the RS485 protocol, allowing developers to easily implement RS485 communication in their applications. The STM32 microcontrollers support both half-duplex and full-duplex communication modes and have built-in hardware support for RS485 transceiver circuits.
To use RS485 communication in an STM32 microcontroller, developers need to configure the UART or USART peripheral of the microcontroller to support the RS485 protocol. The RS485 transceiver circuit can be connected to the UART or USART peripheral, and the microcontroller can then communicate with other RS485 devices.
Overall, the STM32 microcontrollers provide an easy and reliable way to implement RS485 communication in industrial and automation applications.
