Betaflight Current Sensor Offset
Betaflight Current Sensor Offset. Final step is to set the current meter type to virtual. We rely on voltage sensing to decide when we should land.
Current sensor calibration using scale = 877, offset = 18. You will also find a _bl.hex that contains the firmware plus the ardupilot compatible bootloader in case it is not already present on your board. This is the menu where you can adjust each individual esc to get more accurate current sensing values when using an esc that supports current via to digital telemetry.
It Doesn’t Require Any Of The Current Sensor Hardware, But The Current Consumption Is Purely Estimated By Throttle Level.
Your current sensor is inaccurate. There is a section at the bottom on the left call amperage meter for calibrating the current. Set current_meter_offset=36 set current_meter_scale=13 save #save and reboot
Now Briefly Connect Your Load To The V Output Tabs And Have A Look At The Screen:
In betaflight, there are two types of current sensors: Current sensor calibration using scale = 877, offset = 18. But you really need a power analyser or ammeter to measure actual current.
[0] = Motorrangeminincrease * 1000 [1] = Targetrpschangerate (Simple Rpm Error * Idle_Adjustment_Speed) [2] = Error (Amount Of Error To Fix) [3] = Minrps (Lowest Current Motor Rpm, In Revolutions Per Second * 10) So, For Example, A Minrps Value Of 500 Corresponds To 50.0 * 60 = 3000Rpm
Note that while your calibration may be correct there is still a maximum current measure that you may exceed at maximum throttle, this will cause the current recorded by the flight controller to ceiling at this value even if the actual current is higher. Virtual current sensor is a feature in cleanflight and betaflight. The latter being a calculated value based on the readings from your voltage sensor and motor power output.
** From Betaflight 3.3 ** Voltage:
It can be a handy tool to have in your quad if you wish to have current sensor capability but not have the hardware. The voltage sensor is usually prominently displayed on the osd while flying. As the docs state, the virtual sensor needs to be calibrated with an offset and scale parameters using two recommended methods:
2 Groups Of 9V Output, The Total Current Load Is 2A.
Current_meter_offset $ = 0.36 * 100 = 36$ with the calculations finished get back to the betaflight configurator. I did not see a gui version for this and the cli value differs between cleanflight and betaflight as follows: Physical, actual current sensors (shunt resistors) built into the flight controller;
