You will design two embedded systems with multiple inputs on one microcontroller and output via a single controller. That employs 12C communication, timer interrupts to sense the data at different times and an external interrupt on microcontroller 1 to stop the sensing. Outputs will be shown on microcontroller 1. This can be viewed in Figure 1 and Figure 2. Use Timer Interrupts to poll sensors at different frequencies Use a button at C1 to stop sensing C 2 using external interrupt Analogue 0-5V I/P #1 ADC #1 Analogue 0-5V I/P #2 12C Communication C 2 ADC #2 Figure 1 initial Embedded System in Hardware and Software Use Timer Interrupts to poll sensors at different frequencies ADC #2:1 HC 2 12C Communication ADC #2:2 Use a 3-way switch at C 1 to stop sensing from each of the uc using external interrupt ADC #3:1 C 1 Analogue 0-5V I/P #2:1 Analogue 0-5V I/P #2:2 Analogue 0-5V I/P #3:1 Analogue 0-5V 1/P #3:2 Analogue 0-5V I/P #4:1 Analogue 0-5V I/P #4:2 C 1 C 3 C 4 12C Communication ADC #3:2 ADC #4:1 12C Communication ADC #4:2 Figure 2 Enhanced Embedded System in Software Digital Output #1 Digital Output #2 Digital Output #1 Digital Output #N Design Specification Convert your sensors program to have multiple functions - one for each sensor Get your temperature and light sensor to auto-calibrate - by using the function Add a second Arduino 12C serially send input data from a single analogue sensor connected to Arduino 1 using I2C to Arduino 2 and output this, to a component, such as the serial monitor or LCD display Add an emergency stop/start button to Arduino 1, that turns off sensing and sending - implement this as an external interrupt Modify your programme to use a timer interrupt to read from different sensors at different time intervals as required, ex: temp sensor every 1s, light sensor every 10s Finally add two more Arduinos (Figure 2) each with 2 sensors and report all of the readings on Arduino 1.
