We have STM32F103RTB6 based embedded module with 3.2"TFT Touch screen. We have used the UART1 for debugging and other interface function. The project is working stable now.
Current project uses - "rt thread" compiled in KeilC
Freely available Pins are PA0,PA1,PA2,PA3
Our Requirements are:
1. We want to add the MODBUS SLAVE RTU communication to the existing Project to Read/Write few registers ( up to 12 Registers). UART2 must be utilized.
2. The communication protocol is Fixed 8 Bit, 1 stop bit, No parity,
3. The baud rate should be selectable as 9600,19200,57600, 115200 in the communication screen.
4. Communication via RS-485, It requires TX,RX switching through MAX485 IC.
We will supply the existing source files to the winning bidder.
