Sensor: hydraulic sensor, 12vDC, RS485 data output, Modbus protocol communication. 2. Circuit: according to the sensor properties, the circuit is mainly composed of two parts, communication circuit and power supply. Connect jumper cap W1 and W2 to use RS485 to send and receive, not to connect is common serial port transceiver. I have two device ( ISL83485 + STM32), and they connected on RS485 line. I want to send some UART signal to RS485 line with a tranceiver. I am using ISL83485 tranceiver for this purpose, I am using stm32f4 proccessor. When I transmit data under UART2, I can see the data in UART_TX pin of the tranceiver with the osciloscope.STM32 USART (interrupt mode) Example. The STM32 USART_Irq example program shows how to configure and use the USART1 of STMicroelectronics STM32F103xx microcontroller in interrupt driven mode.
