An in circuit serial programming ICSP header is provided so that you can easily upgrade the firmware inside the PIC microcontroller in future if you make any changes.Īn external reset is helpful to bring the entire system to a known initial condition, when the microcontroller stops executing the program for some reason. LCD module, then you may not have a back light facility and you can ignore the pins 1. This will protect the microcontroller from any possible damage due to high voltage input. V Zener diode across the R1 resistor, the output voltage Va will never exceed 5.
Using two resistors, R1 and R2, the input voltage ranging from 0 2. It can be achieved by a simple resistor divider network shown below. So, first we need a voltage scaler that will scale down the input voltage to the safe operating voltage range of PIC1.ĪrtCAM. It is too higher than its operating voltage, and the microcontroller could be damaged. Doing some math with ADC conversion you will see later, this number can be converted to the actual measured voltage. V, but you can easily increase or decrease the range of input voltage as your requirements after you understand the voltage scaling method described in this project.ĪDC. This project will describe how to make a simple digital voltmeter DVM using a PIC1. Mikroc Pro For Pic Crack By daverformver1978 Follow | PublicĪ major source of error in this project is the accuracy of R1 and R2 resistors.
