How can I prepare the code??? I mean I want to reduce the keypad from 4 keys to 3 keys.... I am using pic16f877 with hi-tech C compiler.. Thank you,
Dear Friends, I am working on TImer 2 of pic16f877. Code is given below. void main() { TRISB0 = 0; RB0 = 0; inittimer2(); while(1) { } } void inittimer2(void) { TMR2 = 0x00; T2CON = 0x75; // Prescaler 4, Postscaler TMR2IF = 0; TMR2IE = 1; PR2 = 0xFF; } void interrupt ISR(void) { if(TMR2I
Hi guys. I'm new to this C programming language. is it possible to display the temperature that measured by LM35DZ to led DOT matrix display? i cant find the tutorials everywhere. Attached the led dot matrix datasheet.
hi ! I'm trying to to make a led light on when i push the button ! here is the situation : - when I push it for the first time, the led lights and switch off after a delay ! but if I push it the second time and she's still lights ( in the delay ) it should turn off I made this prog ! but it didn't work ! I forgot to mention I'm working on p

Simple short code for led Chaser in MikroC : Also you can easily get assembler code in MikroC if you need. The code is the same for pic16f877, just choose that uC in project settings and adjust oscillator. Best regards, Peter
Hello! nice evening to everyone. I am beginner in c programming and I need your help. I know this is the most engineering and programming engineers forum:) please help me. I have 64 leds I have to control them with 3x4 keypad (for ex: I touch 24 in keypad than the 24. led lights) can anyone help me with this please? something like that [ATT

hi although pic16f877 is too big for this task a small 8pin pic can do it neatly and also save cost as well here is what you need programmable led strobe led Strobe regards Fragrance
I would need your help in my project, I want to use a Temp sensor LM35 along with PC16F877A to monitor the temperature and control the level of Air Conditioning, like: Less than 20C: Off , both leds off , and show the word "OFF" on a display. 20C-40C Low , led1 ON only, and write "LOW" on the display 40C-60C High, led2 O
Hi guys, Do you guys know on how to make a led blinking for pic16f877 using Mplab IDE ? Any links / tutorials ? Thanks
hi anyone here, it first time to program microcontroller practical i begin with pic16f877 with simple program to light and turn off led with delay at begining the circut work correctly but after few test it damaged i try to connect it again but there are no result can any one give me some suggestion
hi guys! m doin project on pic microcontroller to have led sign board at the main entarnce of the i think that matrix leds are envolved for switching i want a schematic diagram to interface it with pic16f877..and one more question can it be implemented using one Ic..if i want to display "ACADEMIC BLOCK" so i want a help on this
hi..does anyone have a schematic and/or know a tutorial on how to interface a gsm module to pic16f877,pic16f877A or a 8952 ?C?:?: we need it as soon as possible :cry: the project is an electronic message board via sms and we're planning to use a gsm module to receive the message.. the message would be displayed in the led dot matrix..
