We need to make a communication device to communicate with its connected slave device.
The project is based on STM32 controller
The project hardware has 2.8" touch TFT screen and RS485 communication
Few group of values called as Recipe should be available in the STM32 flash area, the values should loaded to the respective register fields during power ON. The user will change the values in the input fields. The updated values should be stored back to the flash memory.
The project has to establish communication and Read/Write register values of the connected slave device. The stored/edited values should be write to the connected slave device though its UART2 whenever required. Another screen should Read the values of the slave device and show in to the TFT display.
We have a similar program with MODBUS RTU SLAVE, for the same HW. If winning coder required , we can supply.
Delivery of full source code is required.
