On the Meshbean board UART1 is routed either via a FT232BM USB converter to connector CN1 or via a RS232 level shifter to header P2. The selection is done with jumper J3.
#define HWTMR_PRESCALE (1) |
Timer is clocked at F_CPU, and TIMER_IRQ_vect is called every 65535 ticks.
#define LED_DDR DDRB |
DDR register for LED
#define LED_MASK 0xe0 |
MASK value for LED
#define LED_NUMBER (3) |
number of LEDs for this board
#define LED_PORT PORTB |
PORT register for LED
#define LED_SHIFT (5) |
SHIFT value for LED
#define LEDS_INVERSE (0) |
a 1 at the PORT means the LED is off
#define MAX_FRAME_SIZE (127) |
maximum allowed frame size
