BaseCam SimpleBGC 32-bit

The BaseCam SimpleBGC 32-bit controller is used for the construction of high quality 3-axis camera stabilizing systems. This board is deployed in handheld and boom-mounted cameras in many systems available worldwide.  There is increasingly also use in aerial vehicles (uav's).  With its 32-bit ARM processor the board possesses enough power for any practical level of complexity for algorithms, and together with premium MEMS gyros it uses high-efficiency FETS which gives it enough power to drive most cinema grade equipment when properly configured, yet at just 22grams for the board itself it is small enough to fit into just about any application. For micro vehicles and single-handed applications or anyplace space is limited there is also a smaller version of this same board (see SimpleBGC 32-bit Tiny board for more information). The smaller board is very similar- with all of the same functionality in an even smaller package.

This version of the controller (and the new Tiny 32-bit board) is our new direction in the development of the stabilizing solutions. It replaces the previous 8-bit version of the SimpleBGC controller keeping 100% backward compatibility for users replacing an older controller with this one who need all of the functionality of the old controller to be the same in the new controller (in order to fit into the existing system with a minimum of effort).  In addition the management software is backward compatible, so it is possible (or likely) that users of older 8-bit controllers are using the newest version of the management software.

Capabilities

Possibility to manage the system on different platforms
Desktop systems: Windows, MacOS, Linux. The firmware of the controller is user upgradable (through the GUI).
Smartphones: Android and some control from 3rd party vendors for Apple's iOS product (iPhone and iPad).

Open Serial API
Open programming interface for development of external control modules — both for software configuration and control of the board and for communication with various electronic devices.

Automatic tuning of PID parameters
Automatic tuning of PID parameters allows you to quickly prepare the system for work either at the initial settings or at changed conditions.

Support of systems with various configurations
Flexible customization of the sensor orientation.
Support for a wide range of engines of various configurations and sizes.

Support for two sensors
The system works with either one or two IMU sensors. The use of two sensors improves stability and accuracy.

Optimized control algorithm
The algorithm uses no more than 30% of CPU power and has a large reserve for future opportunities.

Operation of the system at any angle
The system operates at any inclination of the stabilizer frame, and has several modes of operation: Briefcase (90 degrees rotation ROLL) and Upside Down as well.

Different algorithms of follow mode
Flexible configuration of the follow mode for each axis.  Automatic switching of horizon axis mode from lock to follow in case of persistent camera tilt.

Adaptive PID-algorithm for preventing vibrations

Up to five user-configurable modes of system operation with a toggle button

Support of a wide range of external control protocols
Futaba, Spektrum, 5x PWM, Sum-PPM, 3 ADC.
Flexible configuration allows for control of any functions of the system (every parameter that the system uses is configurable).
The system can decode Futaba / Spectrum and provide PWM to control servo drives.

Battery voltage drop compensation
Battery voltage drop compensation ensures proper control of the drive motors during the whole life of the battery.

Different versions of the controllers for different needs
The licensing system allowed our partners to launch different versions of controllers for a wide range of applications: from compact controllers for stabilizers of light cameras to powerful ones for the stabilization of heavy units.

Ongoing work to improve the system
BaseCam Electronics is working closely with the developers of end devices, which allows us, on the basis of feedback,  to continuously improve the stabilization algorithms and expand the capabilities of the system within a single version of the controller.

Rev. A Important Notes

A. Some versions of this board may have minor error in labeling outputs: On boards having the mis-labeling ROLL and PITCH motor outputs should be swapped. You can check this by disabling all motors except the ROLL axis and connecting the motor to the ROLL output. If it does not work, labeling on your board is incorrect, take it into account.

B. Some versions of the controllers can have a problem with the spektrum port: satellite receiver does not get enough power from the 3.3V internal voltage regulator, and it may function incorrectly (simptoms: signal interrupts, LED blinks randomly, on binding attempt system goes to reset). Possible workarounds:
1. Power the receiver from an external 3.3v power source (preferably a regulated battery supply).
2. To solder additional 3.3v LDO regulator into the controller. The best choice is 3-lead TO-92 package (for example, LP2950-33, L4931CZ33-AP, L78L33-ACZ).  Soldering additional LDO voltage regulator 3.3v
