lcdfout()

void lcdfout	(	const char *	format,
			...
	)

Display formated text.

To use this function, include tucbot_additionals/fout.h into your code.

#include <tucbot_additionals/fout.h>

int main(void) {

    init_tucbot(0xFF);
    battery_request(kRequestWait);

    while (1) {
        lcdclr();
        lcdfout("V=%d",battery_get());
        mdelay(1000);
    }
}

Parameters

format	Format string. String description %c Output of an unsigned 8-bit value %i Output of short (16-bit) %li Output of long int (32-bit) %s Output of character string %x Output an unsigned int/short in hex style
...	For each place holder, a variable has to be added as parameter of the function

Note

As this function uses printf functions and their variants, the generated microcontroller code will grow in size. Especially, if floating point values are to be printed out. For this reason, floating point formating is disabled by default within the makefile (see PRINTF_LIB).

The display shows only 2*16 characters. Switching to the next line has to be done manually with lcdxy(0,1).

lcdstr()

void lcdstr

(

const char *

send_data

)

Writes a string located in the RAM to the display.

This function loads the referenced string character by character and writes those using the lcdout() function until a terminating \ 0-character is found.

Parameters

*send_data

16-bit pointer to a character located in the RAM

lcdstr_p(), lcdout(), lcdxy() and lcdclr()

lcdstr_p()

void lcdstr_p

(

const char *

send_data

)

Writes a string located in the flash to the display.

This function loads the referenced string character by character and writes those using the lcdout() function until a terminating \ 0-character is found.

Parameters

*send_data

16-bit pointer to a character located in the flash

lcdxy()

void lcdxy	(	uint8_t	x,
		uint8_t	y
	)

Moves the cursor to a postion on the display.

The column is set by the x parameter and can be between 0 and 15.
The row is set by the y parameter and can be between 0 and 1.

Parameters

x	8-bit unsigned integer (0..15) 0 is the most left character. 15 is the most right character.
y	8-bit integer. (0..1) 0 is the upper line. 1 is the lower line.
