    MikroC & SD CARD & PIC18F4520

    you have to connect the E pin and RS to the microcontroller and R/w to ground.after writing command/data to the lcd data bus a pulse should be given on the E pin to transfer the command or data to lcd.if one row of lcd is with dark squares when u give the supply then its working, but the...

    how to check signal input(pic16f627a)

    Try this: main() { CMCON = 0x07; //comparator must be turned off for digital i/o operation TRISA = 0x01; while(1) { start: while(PORTA.F0==1) { delay_ms(20000); while(PORTA.F0==1) { PORTA.F1=1; delay_ms(3000); PORTA.F1=0; while(PORTA.F0==1) { } goto start; } } { } } }

    power regulator efficiency

    For a (or any) circuit, the supply current should be greater than or equal to what the ckt needs for its proper working. this means ur regulator have the capacity to drive a circuit which needs 8A current.

    analog signal to digital problem(program)

    hi, you should initialise the ADC module and read the value from the ADC result register (this is not present in your program given). also not specified about the microcontroller (if you are using it) and the compiler

    Help with parallel port programming

    And I did forget to mention something. I had accidently interchanged the GND and LPT pin 9 connection. Could this have damaged the port ?? pls read this topic to test your port https://www.epanorama.net/circuits/parallel_output.html
