This example code introduces how the CM2003 series microcontroller (MCU) reads the differential channel of the 24-bit Analog-to-Digital Converter NADC24 through the USCI interface to collect the temperature signal of the external thermocouple sensor. The temperature signal is read and transmitted to the USB to RS485 adapter using the Modbus protocol over the RS485 interface. The USB to RS485 adapter is then transferred to the PC for analysis.
The Modbus protocol uses the open source FreeModbus protocol stack. FreeModbus is widely used in the development of embedded Modbus devices due to its open source, lightweight and easy portability. Developers can customize and optimize it according to project requirements.
