The circuit diagram and the prototype built on a breadboard are shown below. Therefore, the user must ensure the bits in the TRISA register are maintained set when using them as analog inputs.

Since the PIC port cannot take 20V input directly, the input voltage is scaled down using a simple resistor divider network. A resistor divider network is used at the input end to map the range of input voltage to the ADC input voltage range V.

Digital I/O Ports in PIC16F – Embedded Lab

The mode of operation of each pin is selected by initializing various control registers inside the chip. I have been trying to install microC pro suite and microC compiler on my windows 8 system but I found out that the software does not have drivers for windows 8. Leave a Reply Cancel reply. Each of the pin can be selected as input or output by setting or clearing the corresponding bit in the TRISC register. The technique is demonstrated for input voltage ranging from V, but it can be extended further with proper selection of resistors and doing the math described below.

Some snapshots of the testing are here. How I measure 30 Volt in this meter… Its show maximum Similarly, the PIC16F port pins that are multiplexed with ADC channel inputs are also configured as analog inputs on a power-on reset. The voltage to picc16f688 measured is fed to one of the 8 analog channels. A bidirectional port is one that can act as either an input port, to receive information from external circuitry, or an output port, pic1f688 give information to external circuitry.

PIC16F688 Digital Voltmeter

This project describes how to make a digital voltmeter using a PIC microcontroller. I measured R1 and R2, and their values are and Ohms. This site uses Akismet to reduce spam.

Thank you very much for the wonderfull project. The DVM is tested for various input voltages ranging from V and found to be very accurate. PIC16F is a pin flash-based, 8-bit microcontroller.


Festine July 12, 6: In order to use these pins as digital pic16v688, the comparators must be turned OFF. All these options will be discussed later on.

I thank you all for this piece of materials that you have been able to put together to help students who are interested in learning how to work with Pic microcontrollers.
