mjr 47:df7a88cd249c 3 // The SimpleDMA class has provisions to assign channel numbers
mjr 47:df7a88cd249c 4 // automatically as transfers are performed, but auto assignment
mjr 47:df7a88cd249c 5 // doesn't play well with "channel linking", which we use in the
mjr 47:df7a88cd249c 6 // TSL1410R code. Channel linking requires us to know the hardware
mjr 47:df7a88cd249c 7 // channel number of the link target before any transfers start.
mjr 47:df7a88cd249c 8 // The only good way to do this is to pre-assign specific numbers.
mjr 47:df7a88cd249c 9 // And once we start doing this, it's easiest to assign numbers
mjr 47:df7a88cd249c 10 // for everyone.
