This the temperature and humidity acquisition terminal program complete implementation, debugging success. Modbus protocol implements the 3rd command data collection, using STCSTC15F2K60S2 microcontroller, using a simple task with priority scheduling system, temperature and humidity sensor model AM2302,, temperature and humidity through the static display driver 74HC595 four digital tube display rotation , 2 button click once to look up the maximum and minimum temperature and humidity, uart1 as the debug port, data through max485 achieved through uart2 485.
