| Andrew F. Davis | 24b9dea | 2016-05-01 15:36:58 -0500 | [diff] [blame] | 7 | specific stage number corresponding to datasheet stage names |
| 8 | as follows: |
| 9 | 1 -> LED2 |
| 10 | 2 -> ALED2/LED3 |
| 11 | 3 -> LED1 |
| 12 | 4 -> ALED1/LED4 |
| 13 | Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1 |
| 14 | respectively which simply helper channels containing the |
| 15 | calculated difference in the value of stage 1 - 2 and 3 - 4. |
| 16 | The values are expressed in 24-bit twos complement. |
