pic microcontroller

Hello everyone. Im have some trouble getting an LCD to work with a 4*4 keypad and pic16f690. The code works in proteus, but when i test on the breadboard, will all the same connections, it does not display anything. What could be the problem? I have attached the code and circuit design below...

I am quite new to assembly programming and I am trying to create a switch statement. I was using the Microchips example but it does not seem to work in my simulation. Here is my code. It supposed to go to label2 but it skips all the conditions. Any help will be appreciated Mod: wrapped your...

Hello I am trying to make USB connection to PIC18f14k50. Following are connections :- Pin 1 (Vdd)------>5V Pin 2 & 3 -------->External crystal oscillator (20MHz) Pin 4 (MCLR)------------->Pulled high with 10K Pin 20 -------------------->GND Pin 17---------------------> capacitor (0.1UF)...

I am creating a project of temperature indication using thermistor with pic16f877A. and 4 channel 7 segment Display. The problem I am facing is Using timer to read adc values and converting to Celcius makes my 4 channel 7 segment display to blink after every 2 Seconds. At ln0 line the display...

Hello, I am trying to replace a potentiometer in my project with MCP41HVX1 so that I can control the output voltage of LM317 regulator. My current LM317 circuit is as below: I use 2pins of J2 POT (between ground and wiper) to vary the voltage output of LM317 regulator. When POT has 0Ω...

Hi all, I am trying to program the PIC12F1571. It has 4 channel ADC but I can only enable the AN1. The rest just doesn't work. Even using CCG which you can enable the physical pins, you can not enable any of the other channels. Does anyone else have come across such an issue? Every video on...

I've recently been design a PIC development board with USB and other peripherals, I've got the board working, got code running on the board and managed to test all of the peripherals that worked great, until it came to USB. The issue isn't the USB circuity its self, I've recently brought a new...

Hi, I'm on a project where I would like to measure a battery voltage. For that, I have to use a Digital Current and Power Monitor, called INA260. I already have a board made and it's functional because I've already tested it with the arduino, but I'm not able to do the programming on the...

I have made a circuit in Proteus with the PIC16F887 for measuring the voltage, current , power and also power factor and display them on the LCD. In the circuit, the L1 and R5 can be any value as it is just a value for the load connected to the circuit. I was wondering if I were to place some...

I am using PIC16F18875 controller in my design but i am planning to switch to a higher clock pic from pic18f series. I was looking for microchip product selector but I want suggestion before picking up randomely.

hello Everyone, Iam new in Microchips system, we looking for Microchips Professionals to help us with our problem. We have a project that needs to be developed and modified, but we could not because we do not have the source for development, All we could do was extract a .hex file from our...

Hi, I am using the PIC12F1571 MCU in our latest design. It is connected to two sensors (TSSP58038- Proximity, IRA-S210ST01- PIR sensor) with analog input. The PIR is connected to RA0 and the Proximity sensor is connected to RA2. The program: As soon as the PIR sensor detects anything(Goes to...

I don't know if this has been asked before, but I'm doing a project where I need to sense temperatures and humidities of an enclosure, using a PIC32 microcontroller. Is there a way to save the data from the sensors to a CSV file? Thanks in advance!

I'm tryng to make a DC motor into a servo motor. The motor axle has a gear that is in sync with a gear on a potentiometer (MOTORPOT in the code) and I have another potentiometer that works as an input that the motor potentiometer should match in position however I set this pot(CONTROLPOT in...

Hello everyone, I am having some doubts about how to insert an anti-windup on my Microcontroller PIC dsPIC33EV. I designed a PI controller to control the charging of a batterie and I think all expect the Anti-wind up is correct. I will insert a screenshot of the C code I wrote of the Controler...

I would need some help with the external interrupt on pin 33 on the PIC16F887(PDIP). Basically I have tried everything, went by the datasheet, and the interrupt ended up not working. I'm 99% sure, that I have the hardware working because it worked with an Arduino. I am using an encoder, and both...
