(TCCR1A.... are the low level timer register for AVR (="Arduino" 8bit). Please start here: <a href="http://leaflabs.com/docs/hardware/maple-mini.html" rel="nofollow">http://leaflabs.com/docs/hardware/maple-mini.html</a> and here <a href="http://leaflabs.com/docs/hardware/maple-mini.html" rel="nofollow">http://leaflabs.com/docs/hardware/maple-mini.html</a> for the fundamental basics you need to know. In other words: There is no sense converting the AVR timer library, because you can use "Hardwaretimer" (second link) regards Matthias tormod on "Some Problem with timer(in I2C mode)" http://forums.leaflabs.com/topic.php?id=74416#post-105662 Sun, 22 Feb 2015 04:47:41 +0000 tormod 105662@http://forums.leaflabs.com/ Roger, thanks for linking to that active forum. But wouldn't it be better, if that is going to be the "official" forum, to not have everything in one thread?

When I solve other problems, I find this warning"error:'TCCR1A' was not declared in this scope". I know TCCR1A is a timer,but I don't know how to solve this problem ,please help me. thanks :D! void InitPWMInterrupt() { #if (DEBUG) Serial2.println("PWM interrupt initialized"); #endif TCCR1A = (0 << WGM10) | (0 << WGM11) | (0 << COM1A1) | (1 << COM1A0) | // Toggle pin om compare-match (0 << COM1B1) | (0 << COM1B0); TCCR1B = (1 << ICNC1)| // Input capture noise canceler - set to active (1 << ICES1)| // Input capture edge select. 1 = rising, 0 = falling.
