PIC16F – Microcontrollers and Processors – Microcontrollers and Processors

Each of the pin can be selected as input or output by setting or clearing the corresponding bit in the TRISC register. 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. Thank you very much for the wonderfull project.

Your pic16f868 address will not be published.

Please if there is a link that I can download this drivers please help me out by sending the link to e-mail. A resistor divider network is used at the input end to map the range of input voltage to the ADC input voltage range V.

Festine July 12, 6: In order to use these pins as digital inputs, the comparators must be turned OFF. The voltage to be measured is fed to one of the 8 analog channels.

All these options will be discussed later on. Leave a Reply Cancel reply Your email address will not be published.

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

The mode of operation of each pin is selected by initializing various control registers inside the chip. By continuing to use the site, you agree to the use of cookies. Can you please give the hex file, without changing the resistors for 30 Volt?.

Therefore, the user must ensure the bits in the TRISA register are maintained set when using them as analog inputs.

This project describes how to make pi16f688 digital voltmeter using a PIC microcontroller. 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. 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.
