printf(), lcd_putc() and ROM space

[Tommy Liu]

Hi,

The following:

printf(lcd_putc ,"\fMessage\n");

can be replaced by the following:

lcd_putc("\fMessage\n");

to save ROM space.

Can the following statements be represented by lcd_putc() or another format to save ROM space?

printf(lcd_putc,"\%4.3fV(ADC=\%4lu)", volt, ADC_value);

printf(lcd_putc,"\fFAILED at pos=\%u\n", pos);

Thanks in advance.

--------------------------------------------------------

In the code above, the printf is doing a conversion from
the float and "unsigned long" data types to ASCII.

The lcd_putc() function can not do this conversion.

Thanks for your explanation. It is what I thought as well.
