Use the MC9S12XS128 microcontroller to design a single-chip application control system. The single-chip
computer
uses the MC9S12XS128 single-chip computer to design a single-chip application control system. The system can not only display the values of indoor temperature, humidity and exhaust gas concentration in real time, but also control the indoor temperature, humidity and exhaust gas concentration according to preset parameters. Exhaust gas concentration. The preset parameters can be input or changed through the control keyboard, and the execution devices are ventilation fans and electric windows. In addition, users can also directly control the opening/closing of windows, starting/stopping of ventilation fans, raising/lowering of temperature (humidity), and selecting the type of displayed parameters through the control keyboard.
To design a microcontroller application control system based on MC9S12XS128 microcontroller, the main functions involved include:
Real-time display of indoor temperature, humidity and exhaust gas concentration values.
Control indoor temperature, humidity and exhaust gas concentration according to preset parameters.
The input or change of preset parameters can be operated through the control keyboard.
Control switches for ventilation fans and electric windows.
Users can directly control the opening/closing of windows, starting/stopping of ventilation fans, raising/lowering of temperature (humidity), and selecting the type of displayed parameters through the control keyboard.
Below is a basic design framework that you can adapt and extend based on your specific needs and hardware connections.
Hardware connection:
Connect the indoor temperature, humidity and exhaust gas concentration sensors to the analog input pins of the MC9S12XS128 microcontroller
