void bk_LED (  int8_t  value  )

Function to connect to property "Backlight brightness". Form defined through the first function-pointer in struct menue_prop_struct in menu.h. { if(value >= 1 && value <= 11) OCR2 = (value-1) * 12; //10*12 = 120 }

void call_inits (  void   )

{ init_ports(); menu_init(); control_init(); input_init(); adc_init(0); disp_init(); usart_init(); interrupt_init(); }

void init_ports (  void   )

{ DDRA=255; //OUTPUT PORTA=255; //on DDRC = 0; //Input PORTC = 255; //pull ups DDRD = (1<<PD3); //PD3 Output PORTD = 255; DDRE = 0; //input PORTE = 255; }

void interrupt_init (  void   )

Enables Timer2 for Backlight. Enables Timer3 for micro-second measurement. Enables interrupts globally. { //timer 2 in fast PWM for backlight PORTB &= ~(1<<PB7); DDRB |= (1<<PB7); //OC2 pin is output TCCR2 = (1<<WGM21) | (1<<WGM20) | (1<<COM21) | (1<<CS20); //no prescaler TCNT2 = 0; OCR2 = 108; //max 120 //timer 3 for us_timer us_timer_init(); // enable interrupts sei(); }

int main (  void   )

Main, with test-code. { //#define cnt 1 DDRE = (1<<PE2); //sets data direction for xck0 to output call_inits(); #ifdef DISP_SPLASH for(uint32_t x=0; x < 5000000; x++) asm("nop"); #endif while(1==1){ //uart_empfang(); control_refresh(); disp_refresh(); input_refresh(); } }
