First of all, when you say keypad are you thinking of a matrix? If so, how many keys in the pad? How many keys in total? How many pins are available on your pic for this keypad interface?
Probably this will help. Not for pic or MikroBasic, but its the same principle.
Hi all, How to interface 4 x 4 keypad with pic micro-controller (pic 16F877A) with detail : The numbers 0-9 will be used as the decimal operands and letters to specify the operation: F will carry on the addition ? + ? of 2 digits E will carry on the subtraction ? - ? of 2 digits C to (...)
Hi, Can somebody share the code for a 4x4 keypad interfacing with pic32 controller. Best Regards.
HI, I am repeating... I am doing a project to get input data from a 4X3 matrix key pad (just as in mobile) and display it in lcd using pic 16f877A.... the keys are like (.,1),(abc2),(def3),............(wxyz9).... i dont know how to write code for key identification as it uses multiple character in a single key..... if any one know
See my example RF Remote. See video. At transmitter, I send 3 byte UART. 0xFF, upper 4 bit PORTB, lower 4 bit PORTB At receiver, I receive and store in 3 array. rf, rf, rf. Then combine rf and rf to get PORTB.
A LCD and keypad interface coupled with some C code and you are on your way. pic Calculator Project There are other examples on the NET, just search for 'pic Calculator.' Hope this get you pointed in the right direction.
Hi all, I want to interface my keypad with the pic24F microcontroller (pic24FJ64GB002) with pic PCWHD compiler. I have my lcd hooked up already and its working fine but now i cant seem to get the keypad working. This is how my LCD is configured, (...)
I suppose you could also use any mcu (pic, avr) to do that job instead of a dedicated chip and it would also be easily customizable with different keypads. I don't know the cost of your mentioned chip so i can't judge which solution is cheaper. You can also use an i2c port expander if you already have an mcu in your project and you don't (...)
Dear friend, Below program is for 4*1 keypad reading. list p=pic16f877a #include"p16f877a.inc" cblock 0x20 r0,r1 endc org00 goto main org 04h retfie main bsf status,5 bcf status,6 movlw 0xf0 movwf trisb movlw 0x00 movwf trisc bcf status,5 bsf portb,0 top btfsc portb,4 goto l1 btfsc portb,5 goto l2 btfsc portb,6 goto l3 b
firstly, do your program needs something more? or it's just detect input pulse and then bang! output on PORTB... so to rearm the system just a reset? does it will have some user interface? (lcd,keypad) if not, you can use the pic INTs inputs, and "wake" from a Sleep() with no more business...(no watchdog no other (...)
pic interface with keypad
Hi, I am a design enginner working on TCA8418 keypad controller. we have interfaced a pic 24f processor with it . The i2c bus is pulled up with a 3.3 k pullup resistor and 1.5 k series resistor for voltage drop from 5 v to 3.3 v as the TCA8418 is a 3.3V IC and pic24f is a 5v chip. Can (...)
I am new in microcontroller. I have task to design pic microcontroller based temperature monitoring and control using pt100 as sensor. Total 8 pt100 are to interface with pic16f877a. Set points are to be given by keypad and display should be on lcd. Control technicque should be pwm.I am using CCS compiler (...)

hey i am doing a project in which i need to interface an alpha numeric keypad with pic controller . the keypad is alpha numeric just like the one in cell phones any help will b appreciated so thnx in advance
for pic16F877A. Help me with the coding please
I need help with assembly pic programming to interface a keypad,16X2LCD and wireless transmitter module (TLP434A). Anyone have any ideas?
Hello All, I am working with a basic pic microcontroller, and I have created my own user interface which performs actions for extra periperhal debugging such as for example,7-segments, keypad, LCD, etc.. I want to be able to during the DEBUGGING process in the MPLAB IDE, obtain the values from say for example PORTB (...)
