Hi I have TM1638 circuit Pinout STP,clk,DIO spi communication diagram attached here , How to interface with pic16f877a ,where is connect DIO pin to controller please guide me Thanks
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 (...)
Hello, This is my project for interfacing DHT11 digital humidity and temperature sensor with Microchip pic16f877a 8 bit microcontroller. The DHT11 sensor uses 1 wire protocol to communicate with master device and the results will be displayed on 1602 LCD display as shown by the following video. The circuit schematic diagram is attached. (...)
Hi, I have not seen the circuit diagram for that board but knowing the pic16f877a chip I think the switch will be intended to switch all four lines at once, cannot see any purpose in switching them in other combinations. ? you say Picpgm stops responding if you move the to the On position. What then is working /can you do with the (...)
ok First of all you need to have some circuit diagram for it....another thing why do you want to use two processor pic16f877a and PIC16F72 ..... My suggestion here will be do this project in LCD than doing in seven segment displays as multiplexing seven segment require one interrupt timer...... Good Luck
Can anyone help me with either a modified sine wave or a sinewave inverter using pic16f877a. I need both the source code and the circuit diagram. Please I will be happy if the source code is in c language.
Hi everyone ... i need a circuit diagram of interface RFID and GSM modem with pic16f877a..
This is the first time Im using a PIC mc. Ive not understood the transmitting section of the circuit diagram where the encoding is done and transmitted via 433mhz rf. It includes a relay for power failure detection and for switch over from main suply to battery supply. Pls help me out on doing the SWITCHING OVER TO BATTERY SUPPLY and the POWER FAIL
in my project i tried to use can module.could anyone explain interfacing circuit? thanks in advance.....
I am going to single phase energy meter measuring project by using pic16f877a.anybody plz help me how to interface pic16f877a with ade7753.i need interfacing circuit of pic16f877a+ade7753. thanks in advance......plz help me.
Hi all, I downloaded tinybootloader, designed a circuit required for it on a matrix board. The circuit diagram is attached below. In the tiny booloader folder, there was a picsource folder which contained several hex files. The one required for me was 'tinybld_16F876A_20MHz' as I am using pic16f877a. I burnt this hex file (...)
Don't Worry.. I will give you the code when i reach home... I had used the JHD12864E and interfaced with pic16f877a.. Till then u upload your code and Schematic diagram
i am hobby kit maker.. i dont know to write progs for pic mcu.. my project is.. making a RFid reader to read the info of card and send to the mcu.. mcu compare the incoming serial bits with already stored bits on eeprom. if compared result get matched with default{stored on mem}code.then it operate a relay... case2: if mismatch found, the mcu byp
Hai, Pleas post a circuit diagram with pic16f877a+str433 RF MHz.
im having problem to light on led using irpd sensor . can anyone help how to make the led on . this is my coding . please . help me anyone :-( #include <16f877a.h> #device adc=8 #use delay(clock=20000000) #fuses hs,noprotect,nowdt,nolvp #use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,parity=N) #byte PORTa=5 #byte PORTb=6 #byte PORTC
hi.. Is it possible to interface RF receiver ( RWS434 ) directly with our pic16f877a ? If so, can u provide me the circuit diagram pls. Thank u
Dear friend, Actually pic16f877a has 4 ports. You can use portd for lcd,portb for keypad and portc for RF.Use porta for sensors. I am not familir with your language, so try yourself I will sufficient logic for u.
can anyone send to me the source code for digital alarm clock with alarm using pic16f877a,ds1307 and lcd. i also need the schematic diagram for the circuit.i`m using mplab ide..thank you very much.
you may check Microchip's own shopping site: Microchip also shows third party programmers that are supporting PIC devices. If you are considering a programmer that can program many PIC devices, i may recommend Xeltek SuperPro. They s
Dear all... I tried to use pic16f877a. Unfortunately I've no programmer board and the software. I only have MPLAB IDE. Please kindly share the circuit diagram of programmer circuit and related software. Thank you very much. Best Regards Lynn If you are seriously into PIC programming, please do purchase a OICKIT2 , direc
I am new person to this,any one know the circuit diagram,coding for LED Moving message (permanent)from PIC 16F877.pls help me
Hello, Check the voltage level to the chip. These chips are pretty sensitive to the supply voltage. I have used the AT45DB081 with pic16f877a. It took me more than one month to make it work. If possible, post your circuit diagram.
