hello...
i'm using pic16f877a for my project. i have written the source code but there are some error when i want to compile it by using ccs compiler. the error is at the lcd.c driver where it state that delay_us as the undefined identifier. is it because i'm using analog input to the adc of the...
hi...
sorry, but i'm not going to display the adc reading..i need to used it in my calculation only..how must i write the code. for example there are two input to the adc that is X and Y. then i have also 8-bit binary input at portb. what i have to do is Z = XY cos (8-bit binary)...can u help?
hi...
how to write the code to display the value taken from adc and display it on the 16x2 lcd?i'm using the pic16f877a and picc pcw compiler...can anyone provide me the code please...tq
hi...
i have to measure voltage and current from the main ac supply 240 ac by using pic16f877a. the voltage and current input will be measured using built in pic adc. im using voltage and current transformer to scale down the input value to 0-5V range. so, i write this code in order to get back...
ok...tq for the explanation of the code...
basically, i want to design digital watthour meter..i have two zero crossing detector circuit which one is for voltage and another one is for current..the output from the zero crossing detector of voltage will be the input for the 8 bit binary counter...
tq for the answer and note...

unsigned char a;
a = ( ( (PORTB & 0xF0) / 10 ) << 4) + (PORTB & 0x0F) ;
what does this code mean?can u kindly explain it further...
for example i have input 11001000 and i want to assign it equal to 360 degree..how can i...
Re: programming pic16f876 to read input AC voltage continiou
hi waseem...
basically i'm having the same problem with quium which is to write the programming part...but in my case, i'm designing the digital energy meter using the pic16f877a..the input is current, voltage and phase...
ok...but before that,if i don't manage to get the current transducer, is it possible if i replace it with the current transformer?...basically i need to take the current from the ac supply and step down it to 5A..
tq for the answer..
but can u explain further about the function of the current transducer..i've read some info on current transducer but not really understand..
