Hi I'm new to PIC microcontrollers. My program is pic16f877a has to take analog input (ex: sine wave) and ADC should sample that analog input with a sampling rate 0.5kHz. That should be displayed on LCD. Below I'm attaching a file , which has code. But that is not working on proteus. I'm using MPLAB IDE and Hitech c compiler.
Can anyone help me out? I have C program in Mikro-c compiler. Temperature sensor using pic16f877a microcontroller code and i want to convert this into equivalent code for MPLAB-c compiler. Can anybody help me with that? Thanks
Hi, Im using pic16f877a microcontroller, im trying to upload my hex file via UART programming. The concept is, befr using the uart programming have to reserve some initial memory for BOOTSTRAP. Top 256 needed for that(0x1F00 to 0x1FFF out of 8KB). After that only user program will occupied. In MPLAB v8.30, i dont know How to reserve the default

Hai, I recently interfaced the DAC mcp 4921 with pic16f877a microcontroller using SPI. THE Process is working fine, when i given the input directly to DAC (ie : value as 600 without using forloop). but if i given the input using for loop and adding each time value 100 using macros the output suddenly increasing... I found little bit

What you are talking about us called Reverse Geocoding and there are several services (e.g. Google) that offer it over the Internet as a free or commercial service (depending on how often it is used). However trying to do this without an internet connection is next to impossible, especially with a small device such as the pic16f877a which has an 8K
This is an interfacing of pic16f877a with a 2-wire serial lcd, this interfacing uses only 2 wires to display characters on lcds like 16x02 or 20x04. This system consists of a shift register and it can be any type of 8-bit serial-in parallel-out shift register such as 74HC595, 74HC164, CD4094.... The following two videos have more details and how

Hi I am working on a project in which I am using 4 pin oscillator pack of 6.25MHz frequency and microcontroller pic16f877a. In configuration word register there are four options for selecting the oscillator. FOSC<1:0> 11=RC oscillator. 10=HS oscillator. 01=XT oscillator. 00=LP oscillator. Which option i select for this mentioned 4 pin osc
This is a simple circuit for controlling an 12V DC motor speed and rotation direction using pic16f877a microcontroller. As shown on the circuit schematic diagram there are 3 buttons two for controlling the motor direction cw and ccw and the last one for stopping the motor. The speed is controlled using potentiometer connected to AN0. The followi
The following video shows the interfacing of pic16f877a microcontroller with 1602 lcd display and DS1307 real time clock and dht11 digital humidity and temperature sensor. The ds1307 uses I2C protocol to communicate with the microcontroller and the dht11 uses One-Wire protocol. The results are displayed on the lcd display. The circuit (...)
One of the main issues in your code is the Watchdog Timer has not been disabled, which will constantly reset the microcontroller when the timer expires, typically you disable this feature when developing code. You might also have issues with the timing requirement of your LCD which typically differ from simulation to real world hardware. I have

NOW i want to send this reading using sms... i want when i send for example "Temperature" to the phone connected to the pic it responds to me as message "Temperature is: 20°" i mean sms communication and i guess it is done by fbus and AT commands, my problem i cannot write the full source code i
Hey guys..can somebody help in my project.. I need a source code and schematic diagram that will turn on the LED if the Ultrsonic sensor US-100 detects an obstacle and will turn off if there is no obstacle using pic16f877a..thank you..God bless..need it badly..
Hi, I just did a google with "ultrasonic sensor using pic16f877a with assembler" and several examples appeared which should give you an idea of how to do it.
if the microcontroller has two SPI interfaces you can implement this idea. However, the pic16f877a and pic16f73 only have one SPI interface so you would have to implement the second in software using bit-bashing if would be simpler to select a device with two SPI interfaces, e.g. use the Microchip product selector

Hi i have connected a potentiometer to pin AN 2 of pic16f877a .The 10 bit ADC converts input from 0-1023 . Now ,i want to transmit the data serially to arduino uno R3 and display on the monitor .I have connected the Tx of pic to Rx of arduino and also have a common ground .I have also created a software serial port in the Arduino so that the one w
Debugging : 0. Make sure your port is working fine...!!! (very common mistake). Put some leds on your port and turn them on and off. In pic16f877a whole PORTA is an analog input and NOT DIGITAL I/O 1. Turn Off all the unused peripherals of microcontroller which are not in use...LIKE ADC, Timer...etc (Some are ON by default in PIC micr
