The fifth version is for the Teensy 3.1/3.2, and uses the four Periodic Interval |
|
|
|
|
Timers in the Cortex M4 processor to support up to 4 simultaneous notes. |
|
|
|
|
It uses less CPU time than the polling version, but is limited to 4 notes at a time. |
|
|
|
|
(This was written to experiment with multi-channel multi-Tesla Coil music playing, |
|
|
|
|
where I use Flexible Timer Module FTM0 for generating precise one-shot pulses. |
|
|
|
|
But I ultimately switched to the polling version to play more simultaneous notes.) |
