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.

I measured R1 piv16f688 R2, and their values are and Pic16f6888.

Each of the pin can be selected as input or output by setting or clearing the corresponding bit in the TRISC register. A resistor divider network is used at the input lic16f688 to map the range of input voltage to the ADC input voltage range V.

Thank you very much for the wonderfull project.

The circuit diagram and the prototype built on a breadboard are shown below. All these options will be discussed later on. By continuing to use the site, you agree to the use of cookies. The voltage to be measured is fed to one of the 8 analog channels.

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. This project describes how to make a digital voltmeter using a PIC microcontroller. Therefore, the user must ensure the bits in the TRISA register are maintained set when using them as analog inputs. In order to use these pins as digital inputs, the comparators must be turned OFF.

PIC16F is a pin flash-based, 8-bit microcontroller. 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.


The mode of operation of each pin is selected by initializing various control registers inside the chip. The DVM is tested for various input voltages ranging from V and found to be very accurate. How I measure 30 Volt in this meter… Its show maximum Please if there is a link that I can download this drivers please help me out by sending the link to e-mail.

I thank you all for this piece of materials that you have been able to put together to help students who are interested in pic16f688 how to work with Pic microcontrollers. Learn how your comment data is processed. Similarly, the PIC16F port pins that are multiplexed with ADC channel inputs are also configured as analog inputs on a power-on reset.

PORTA is a 6-bit wide, bidirectional port. Some snapshots of the testing are here.
