Build Options

Define Documentation

#define HWTMR_PRESCALE   (1)

UART0 is routed to the ISP pins, alternatively, UART1 can be used.

  • CS1[2:0] = 1 : Prescaler = 1
  • WGM1[3:0] = 0 : Mode = 4 : CTC operation

Timer is clocked at F_CPU, and TIMER_IRQ_vect is called every 65535 ticks.

#define LED_NUMBER   (0)
