Tx and Rx working, Ardupilot acknowledging data transferred - Jan 26, 2025
Notes
Consideration of DMAUse interruptConversion settingRegister settings: Higher OSR and digital filter setting lead to higher accuracy and lower noise, but higher covnersion time(refer to datasheet 16.2.5). Current setting: OSR = 3, digital filter = 5, conversion time = 52.92ms. Standard deviation of noise:
XY-axis = 5 mGauss, Z-axis = 7 mGauss.
Sensitivity setting: Gain and resolution need to be tested on breakout board(refer to datasheet 16.2.4) Current setting: Sens-XY = 1, Sens-Z = 0, Gain_Sel = 0
