can_red_2flash()
red led: 2 200ms flashes
can_set_leds(byte in x)
Internal routine to control the bicolor led I/O pin. four leds, all connected in series between +5V and GND. PIC pin is tied to the middle, via 150 Ohm resistor. at 1.7V Vf, they will not light up (both are off) so HIGH will light both lower green LEDs LOW will light both higher RED leds pin_direction = input will light no LEDs.
can_green_on()
green led: on steady
can_led_delay100ms(word in n)
Delays for n * 100 mSec, while maintaining CAN leds
can_led_poll()
implements blinking of CAN leds. call this routine somewhere in your main loop. can led blink states are typically 200ms each, so try to call more often than 200ms.
can_red_4flash()
red led: 4 200ms flashes
can_red_off()
red led: off
can_red_1flash()
red led: 1 200ms flash
can_green_3flash()
green led: 3 200ms flashes
can_green_1flash()
green led: 1 200ms flash
can_green_2flash()
green led: 2 200ms flashes
can_green_blink()
green led: blink 200ms off, 200ms on
can_red_on()
red led: on steady
can_red_blink()
red led: blink 200ms on, 200ms off
can_green_off()
green led: off
can_red_3flash()
red led: 3 200ms flashes
