My controllers use two LEDs to indicate controller status.
\nH1 – DMX Activity flashes to indicate DMX data has been received and processed.
\nH2 – Power \/ Error is on to indicating Power is ON and there are no errors.\u00a0 H2 flashes various patterns to indicate the type of error.<\/p>\n

The change of a relevant channel is indicated by a flashing green LED.<\/p>\n\n\n\n

This error indicator is easily implemented with the following code:
\nvoid indicate(void) {
\nstatic uint8_t count;
\nif (++count >= 10)
\ncount = 0; \/\/ reset every 5 secs
\nif(Blink ==0) CLEAR(H1);
\nelse if (count <= Blink)
\nTOGGLE(H1); \/\/ toggle LED
\n}<\/code>
\nEach error condition is given an unique Odd number.
\nThe LED Flash period is set by an timer overflow.<\/p>\n","protected":false},"excerpt":{"rendered":"
