STorM32 FAQ
Electronics
What connectors are used for connecting the MPU modules to the board?
The connectors for the MPU modules on the STorM32bgc board are Molex picoblade types with 1.25 mm pitch (for a comparison of various connectors see here). They are also known as micro JST 1.25 mm, and it is in fact best to search for this, e.g. on ebay: micro jst 1.25.
Software and GUI
Storing the parameter values to the EEPROM doesn't seem to work
Please double-check that the correct firmware for your board has been flashed. The problem typically happens then e.g. the firmware for a F103RB is flashed onto a board with a F103RC.
Which drivers are needed for the USB?
On Win7 the driver is usually installed automatically (this may take few minutes, be patient). The driver, usable also for WinXP, can also be obtained from here.
Flashing with the usb-ttl adapter produces Windows error messages
If upon flashing you get Windows errors such as mfc110.dll is missing, msvcr110.dll is missing, or application was unable to start correctly (0xc000007b), then first check that you're not using an outdated GUI version. Otherwise, you need to install the VC++ runtime libraries. Download vcredist_x64.exe or vcredist_x86.exe depending on your Win system from here, and run the exe file.
Gimbal Construction
Does it matter where to install the camera IMU sensor?
In principle no, one can mount it wherever it is most convenient (of course as long as it tracks the camera motion). Some folks have however reported that the performance can depend on where the IMU sensor is mounted, depending on the specific gimbal some places seem to be better, i.e. allow e.g high PID values, than others. So, it may need experimenting.
Where should the main board be mounted for correct use of the onboard IMU?
An welchen Achsen darf und oder sollte die 2. Imu montiert werden? What about the axis orientation?
Angenommen die 2. Imu wird nur ausserhalb des gimbals unterstützt: Was ist, wenn man das main board aus Platzgründen an der yaw Achse befestigt hat. Sollte man dann die onboard Imu deaktivieren? Wenn, wie?
Angenommen die 2. Imu wird nur ausserhalb des gimbals unterstützt: Wenn man an den Imu2 Anschluss eine zweite externe Imu anschließt und die ausserhalb des Gimbals montiert, woher weiß das Gimbal dann welche es benutzen soll (onboard oder die am Imu2 Anschluss)?
