Your job is to design a PlC16F877A-based Data Acquisition sub-system for a medical device. The sub-system is to digitize three analog signals: Oxygen Saturation (SpO2), Blood Glucose, and Body Temperature signals and transmit data wirelessly to a computer for analysis and storage. Given that Fosc = 20 MHz, configure CCP1 and Timer1 in compare mode and generate a steady clock tick every 10 mS. a) Answer the following questions: Input frequency to the Pre-scaler _____ Period of the input clock _____ How many input dock periods are required for 10 mS? _____ Pre-scaler value _____ CCP1 Comparison Value _____ b) Specify the following register values (hexadecimal): T1CON _____ CCP1CON _____ CCPR1H _____ CCPR1L _____ PlE1 _____ INTCON _____ c) Write an Assembly-language subroutine to initialize Timer 1 and CCP1 and append it to this test. Research & Specify a 4 096V external voltage reference chip for your design, and find an actual distributor that has the part in-stock. This part will be needed by the ADC.
