// Pinscape Controller DMA channel assignments
//
// The SimpleDMA class has provisions to assign channel numbers
// automatically as transfers are performed, but auto assignment
// doesn't play well with "channel linking", which we use in the
// TSL1410R code.  Channel linking requires us to know the hardware
// channel number of the link target before any transfers start.
// The only good way to do this is to pre-assign specific numbers.
// And once we start doing this, it's easiest to assign numbers
// for everyone.

// Plunger Sensors

// sensor can be reused by other sensor types.
