This fixes spuriously occuring mag spikes in the external mag of Here2. The reason for the spikes was that the fact that the I2C registers were not read out correctly as suggested in the datasheet. Before we were reading out ST1, data, and ST2 in one pass and ignoring the data ready bit (DRDY) in ST1. This meant that we could run into race conditions where the data was not ready when we started reading and being updated as the registers are read. Instead, we need to check the read the ST1 register first to check the data ready bit and then read the data and ST2 if the data is ready. By reading ST2 we then trigger the next measurement in the chip.

PX4 Users
The PX4 User Guide explains how to assemble supported vehicles and fly drones with PX4. See the forum and chat if you need help!
PX4 Developers
This Developer Guide is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.
Developers should read the Guide for Contributions. See the forum and chat if you need help!
Weekly Dev Call
The PX4 Dev Team syncs up on a weekly dev call.
Note
The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the Dronecode calendar.
