ok. thanks codytech.
I see it I will try this

Hello again everyboy, I have a problem. When I use pins of PORTA as input, I want to check the PORTA.F0 is 1 or not. if I check the pins of porta 0,1,2 and 3 my code works.However if I check only PORTA.F0 is 1 or not, my code doesn't work. My code is below which is work; void main() { int i = 1; ADC...

Thank you Mario.

I added the codes is below and now it looks ok.

Thank you for you replies. I use PIC16f877A. I want to use pins of PORTA as input and pins of PORTC as output. My code is below void main() { int i = 1; TRISA=0xFF; TRISC=0x00; PORTC = 0x00; while(i==1){ PORTC.F0=1; Delay_ms(500); if(PORTA.F3==1){ PORTC=0x00; } Delay_ms(500); } } I have a button and...

Hello, I have voltage problem. My code is below. I have a very simple circuit. A connection wire to a LED from PORTC0 pin and a button. I want to know a button is pushed or not which is checked by PORTB7 pin. if there is 5voltage on PORTB7 then LED on. Problem is that there are always 5 volt. on por...

Hi everybody,

I want to convert hex file to c code. Is this possible ?

I wait for your helping.

Thank you....

Thank you for your helping....
I will try this tomorrow night. I hope that I can do it

Thanks again...

My question is that Can i know the instantaneous current value or voltage using micro controller ? Well, you can measure the voltage of the battery by feeding it to a voltage divider (2 resistors in series), with the connection between the 2 connected to an ADC input of the PIC. Make sure the adc i...

There is no idea about the topic. this is interesting

Hi everyone, I have a project about charging systems. The system looks simple :). I have a power supply, a battery, an inverter (to invert 12V DC to 220V AC), and last a lamp. Lamp (220V) <---- inverter (12V DC to 220V AC) <---- Battery <---- 220V (Urban electricity) The electricity needs of the lam...

Eventually, I find the problem. It is a circuit fault.

Thank you everyone.....

I have tried what you are suggesting with your own code, and it works, if you want, you can also use the button function (see help) in your case, it will be: button(&portd,0,1,0) || button(&portd,1,1,0) hope this helps ! regards Thank you for your interest. I tried button function. However, My prob...

your program breaks from the first time !! you must change from: if( (PORTD.F0 !=1) || (PORTD.F1 !=1) ) break; to if( (PORTD.F0 ==1) || (PORTD.F1 ==1) ) break; or if((PORTD ==0x01) || (PORTD==0x02)) and also, you must set TRISD at least to 0x03, because RD0 and RD1 are inputs, Regards Thank you for...

Hello everybody, I have a problem. I have some codes which do not work. It is below. =========================================================================================== void Light() { int k=0,i=1,m; while ( i==1 ) { k=k+1; PORTB=32; // This is ok.
