RS-485 is a multipoint communication which allows multiple devices to be connected to a single bus. I've been trying to implement a basic per-byte UART Rx Interrupt on a STM32F4 board using HAL skeleton code generated by STMCubeMX version 4. Simple half duplex RS485 interface for the FOX Board LX The only serial port enabled to work as RS485 is the /dev/ttyS3. Operations Management. Мое устройство ведомое идентификатор 121. This example was tested on STM32F4-Discovery and does the following things: Configure the GPIOs for driving the LEDs (PD12, PD 13, PD 14 and PD15). STM32F4-DiscoveryでI2C通信やってみた(MHC6352) どうも、polarです。 今回は、STM32で扱える3つの基礎的なデータ通信方式の3つめ、I2Cを扱います。. mikroMedia™ can be used as a powerful programmable dashboard control panel for both hobby projects, but also for the entire systems. I2C modules comparison.
