besoin d'aide sur la commande d'un lcd par pic 16f877
bnj tout le monde ,j'utilise le compiler ccs c, mon but et de convertir un signal analogique et de transmettre le par un rs232 ou tx 433 ,voici le code
Code:

set_adc_channel(0); //the next read_adc call will read channel 0

set_tris_c (0x00);
initialize();
SET_TRIS_A(0xff);
lcd_init();
delay_ms(6);
printf(lcd_putc,"wirless ECG", );
delay_ms(5000);
while(1)
{
signal=read_adc();//ADC_READ_ONLY);//reads the result of the last conversion
delay_ms(50);
output_c(signal*quantum);
if((input(SYNCH_BUTTON)==1))
{
printf(lcd_putc,"synchronisation", );
printf("signal = %2.2F\n\r", signal*quantum);
}
}

et voici ce qui m’apparaît comme erreur
Code:

| undefined identifier lcd_putc
