Functional OSD
- Attitude and Artificial Horizon (25Hz)
- Battery (Voltage, Instantaneous Current, and Current Consumed)
(3.125Hz)
- RSSI % (3.125Hz)
- Heading degrees and bar (6.25Hz)
- Altitude and altitude hold state (3.125Hz)
- Motors armed timer (3.125Hz)
- Throttle (18.75Hz)
  - fast for finer resolution on screen
- 32 bit timing @ 50Hz - entire OSD updated in 32 cycles, or 1.5625Hz.
At most, two display functions called per cycle to keep 50Hz loop
execution time down.
- CLI and EEPROM for full configurability, gives feedback if user
inputs wrong data

Battery Monitor
- Voltage and current monitoring on any ADC
- Configurable in Sensor CLI, gives feedback if user inputs wrong data
- Data available from 'z' and 'o' commands in normal CLI

RSSI
- raw and converted % values available from 'o' command in normal CLI
- Sensor CLI - full configurability including use of any ADC, gives
feedback if user inputs wrong data
