I thank you all for this piece of materials that you have pci16f688 able to put together to help students who are interested in pic1f688 how to work with Pic microcontrollers.

The DVM is tested for various input voltages ranging from V and found to be very accurate. 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.

PIC16F is a pin flash-based, 8-bit microcontroller. Since the PIC port cannot take 20V input directly, the input voltage is scaled down using a simple resistor divider network. Thank you very much for the wonderfull project.


Digital I/O Ports in PIC16F – Embedded Lab

PORTA is a 6-bit wide, bidirectional port. A resistor divider network ipc16f688 used at the input end to map the range of input voltage to the ADC input voltage range V.

Some snapshots of the testing are here. How I measure 30 Volt in this meter… Its show maximum I have been trying to install microC pro suite and microC compiler on my pic166f688 8 system but I found out that the software does not have drivers for windows 8.

The circuit diagram and the prototype built on a breadboard are shown below. Festine July 12, 6: If you continue to use this website without changing your cookie settings or you click “Accept” below then you are consenting to this.

PIC16F688 Digital Voltmeter

A bidirectional port is one that can act as either an input port, to receive information from external circuitry, or an output port, to give information to external circuitry. I measured R1 and R2, and their values are and Ohms. The voltage to be measured is fed to one of the 8 analog channels. Pic16f6688 if there is a link that I can download this drivers please help me out by sending the link to e-mail.


Each of the pin can be selected as input or output by setting or clearing the corresponding bit in the TRISC register. Therefore, the user must ensure the bits in the TRISA register are maintained set when using them as analog inputs.

The mode pc16f688 operation of each pin is selected by initializing various control registers inside the chip. Similarly, the PIC16F port pins that are multiplexed with ADC channel inputs are also configured as analog inputs on a power-on reset.

This project describes how to make a digital voltmeter using a PIC microcontroller. In order to use these pins as digital inputs, the comparators must be turned OFF.
