Lock-in demodulation of infrared source and thermopile signals with reference channel ratio for CO2 and hydrocarbon concentration.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| thermopile | inout | analog | 2 | |
| ppm | out | valid-qualified bus | 16 |
Standards
No external standard applies.
