Hai
I have to print a float number like 32.56565 into an lcd,
Or a long number like 3256565 into lcd.
1. How can I use the 'printf ' to print this into lcd?
Hi tech manual says about writing putchar function.Where to write and how to integrate it to printf?
2.Which is the best way to do bcd conversion for this number in C (Hi tech)?
thanks

putchar is letting out a hex value of a said string or ascii.
If you want to print a number, you must use the printf command with the corresponding instructions.

Thanks for the reply.
The printf function by default prints into the serial port. Am I right?
If so, how to print that into LCD?
As far as I understood, it is to be done by changing the putchar function .But how?

Thanks C- man for the link.
Sorry to say again that still not very clear.
They say that 'putch' is by default an empty function and to print we have to 'redifne ' it. How to do that?
Simply writing a putch(); which will print a charector in lcd or serial port and include it in our application so that printf will call it repeatedly?
Thanks
Please

Hi, using CCS PIC C:
| Code: |
float n;
printf("The Value is %2.5f, n);
//
|
%2.5f indicates: 2 int + 5 decimal, type float, print variable "n"
Bye
