Hi

What will be the best way to adopt to give range to counter using the above code from 4 to 2 volt.

I have made the following code its working fine.
I have a range of 2 to 4 volt for adc, but the problem I'm facing is
that when count goes 11111 like approx at 2 volt, then at 1.9 it again starts fr ...

Hi

I want to know how I will generate a counter of 32 count which will increment or decrement a count by comparing the value from ADC of PIC16F877A.
Thanks

how to convert the floating value into integer or long integer.

hi everyone

I m using Timer2 with PWM for IR transmitter

the format we use is like.

{
setup_timer_2(mode,period,postscale);
set_pwm2_duty(value);
}

In MODE we ...

It works fine when i connect first time to the hyper terminal but when i disconnect & then reconnect in the same window it works but show the data twice of each card some time mix the data of dif ...

_except_ with pins2,and 3 'swapped' on the DB9 connection. Basically the modules are wired to talk to a PC, so the TXD, and RXD connections need to be swapped.

sorry i didnt get the above poin ...

Thanks,
i just want to read track 2 data,
this example for reading data from MCR hope will work fine.

I posted the question on other forums so that i can collect many ideas
now i decided to see the result of card reader on PC by using PIC16F877A.
Simply by connecting the magnetic card reader to PIC ...

I have gone through both the links below plus mcr.c driver
still confused what will be the hardware design.
