12 | * NOTES | |
13 | * The BLOCK_COUNTER registers for the ALS300(+) return a figure related to | |
14 | * the position in the current period, NOT the whole buffer. It is important | |
15 | * to know which period we are in so we can calculate the correct pointer. | |
16 | * This is why we always use 2 periods. We can then use a flip-flop variable | |
17 | * to keep track of what period we are in. | |
