- code to control digital potentiometers via SPI [MM] |
|---|---|
| 2 |
- chip select not SPI CS |
| 3 |
|
| 4 |
- idea: use comparator to determine voltage range, then reconfigure amplifier |
| 5 |
- later |
| 6 |
|
| 7 |
- problem: capacitance of digital poti |
| 8 |
- idea 1: |
| 9 |
- idea 2: logarithmic amplifier using transistor |
| 10 |
|
| 11 |
- ADC driver |
| 12 |
- core [MM] |
| 13 |
- trigger function (we want to read all values ASAP) |
| 14 |
- callback function (once new values are available) |
| 15 |
- init function (initialize ADC) |
| 16 |
- USB integration [HW] |
| 17 |
- simple READ_ADC command |
| 18 |
- one reply packet with all ADC channels |
| 19 |
|
| 20 |
- OS timer |
| 21 |
- how often? |
| 22 |
|
| 23 |
- 'load modulation' driver |
| 24 |
- set PA2/PA3 to binary 0..3 |
| 25 |
|
| 26 |
- add IO definitions for |
| 27 |
- PLL INHIBIT low |
| 28 |
- SPI_SS1_GAIN |
| 29 |
- SPI_SS2_DATA_THRESHOLD |
| 30 |
- BOOTLDR |
| 31 |
|
| 32 |
- sampled data continuous output into file / stdout |
| 33 |
- trigger sampling by raising/falling edge (configurable) |
| 34 |
- sample only one buffer |
