ANALOGUE to DIGITAL (A/D) Converter in PIC16F87X Series

By
ANALOGUE to DIGITAL (A/D) Converter What is a Sample & Sample rate? A "sample" is a single measurement of amplitude. Sample rate is simply the number of samples (or measurements of amplitude) taken per second. Sampling Intervals Quantization The samples are assigned a binary number approximating their sampled value. Quantizing divides up the sampled voltage range into 2n-1 quantizing intervals, where “n” is the number of bits per sample (the sampling resolution). For example, an 8-bit system can identify 28 (256) discrete sampled signal values (255 quantizing intervals). The amplitude of such a signal can occupy the entire quantizing range. A/D Reference Voltages Successive Approximation A/D Example 1 Example 2  Example 3 A/D Converter Modules in PIC16F87X series 28-pin devices has 5 modules.

Voltmeter

By
This code to read an analog temperature sensor, convert the reading to a digital value using the ADC, and display the temperature on a 4-digit 7-segment display. The display is updated periodically based on a timer interrupt. 1.Initialization: Setting up ports, configuring ADC, and Timer0. 2.Infinite Loop: Continuously reads analog input and updates the display. 3.ADC Conversion: Reads analog voltage from a sensor. 4.Voltage Calculation: Converts ADC value to voltage. 5.Digit Extraction: Extracts individual digits from the temperature/voltage value. 6.Display Function: Displays the digits on a 4-digit 7-segment display with slight delays. --------------------------------------------- #include <pic.h> // Include the header file for PIC microcontroller family. unsigned char PORTB_value[10]={0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F}; // Array containing values for 7-segment display. unsigned int a2d_value,temp; // Variables for analog to digital conversion and temporary sto...
