Formatted output
PostPosted: Tue Jun 08, 2004 2:06 pm     Reply with quote
Dear All,

I have bought and regulary use the PCM compiler, which I find easy and
powerful.

As part of an assignment, I have been asked to develop a program with another compiler which does not have the comforts of the PCM compiler

Problem ->

I wish to display a clock in the correct format, i.e when the seconds tick over 9, the seconds occupy two digits i.e

under 10 = 09
above 10 = 10 (ON A LCD)

Normally I would use prinf with a format specifier, this compiler cannot give a formatted output it uses

lcd_print_ch('x');

How can I ensure the correct format is displayed, any ideas??

am i missing something here?

using your example...
Code:

if (x<10)
  lcd_print_ch('0');
lcd_print_ch('x');

Do a test, using the "if" statement. If the value is below 10,
then send a leading '0' character to the LCD.

As has allready been posted, you can do an 'if' test, but the other solution is to use division, and the modulus function.
So (if you 'time' is in 'val', then:
putc((val/10)+'0');
putc((val%10)+'0');
