PLEASE READ THIS FIRST

There are 2 types of IMU modules which STorM32 v1.3x controllers can use, NT IMUs and I2C IMUs, and there are 2 firmwares which correspond to each type. It is important to choose the correct firmware, otherwise your controller and gimbal will not work. Read this page to understand the difference between the two types of IMUs [[1]], and this post to identify your IMU [[2]].

The STorM32 v3.x, v4.x, v6.x controllers can only use NT IMUs, not I2C IMUs.

Only firmwares with version v0.96 or less work with I2C IMUs. Firmwares with version numbers v2.xx are not usable for setups with I2C IMU. If you do not know what a NT IMU is, then you likely have a I2C IMU and need firmware v0.96.

ANNOUNCEMENTS

- The v2.xx firmware series will phase out, i.e., currently it is planned that firmware 2.74 is the last release in this series.
- Development will shift to STorM32 v3. STorM32 v3 will not support the old and tried v1.3x boards, as well as not the v3.3 and v4.1 boards. Reason is that the STM32F103 microcontroller used on these boards has simply become too limited.

v0.96 Firmware for I2C IMUs

Firmware for STorM32 setups using a I2C camera IMU. Examples are the HakRC gimbal and other gimbals from Aliexpress.

Latest firmware v0.96 for I2C IMUs:

o323bgc-release-v096-v20160319 [.zip] (9.4MB)

Note: This wiki here is not appropriate for v0.96 I2C setups, you should go to STorM32 v0.xx Wiki.

Comment: The v0.96 release also includes firmwares for NT IMUs, identifiable by a label "nt" in the file names. Don't use them, use the v0.96 firmware (without a "nt" in the file name).
