Introduction
The sensor power module is responsible for taking telemetry from the environment, logging it to storage and reporting those measurements to other modules. distributing power to the rest of the backplane and therefore requires little software for successful operation. However, power distribution can be monitored and provide valuable insight into the backplane's behaviors.
This page reflects the software design for the second revision of the sensor module
Data
| Name | Data | Type | Size (bytes) | Sample Rate (Hz) |
|---|---|---|---|---|
| INA219 (3v3) | Voltage Power Current | float float float | 32 32 32 | 15 |
| INA219 (5v0) | Voltage Power Current | float float float | 32 32 32 | 15 |
| INA219 (BATT) | Voltage Power Current | float float float | 32 32 32 | 15 |
*** If I did my math right, 15 hertz assuming a default 12-bit resolution for the INA219s.
| Name | Data | Type | Size (bytes) | Sample Rate |
|---|---|---|---|---|
| VIN Voltage | Voltage | int | 16 | 50 |
*** Need to determine good sample rate for the ADC (Consult James)
