HMBGC V2.2 compact, 8-bit brushless gimbal controller based on the ATMega328P microcontroller
Instead of waiting for a memory block to be completely dereferenced before clearing it for the pool, v2.2 utilizes a "dirty flag" system that allows the clearing process to happen in parallel with active computation. This concurrent cleaning ensures that the memory pool remains fluid, drastically reducing the likelihood of an "Out of Memory" (OOM) error during sudden spikes in data ingestion. hmbgc v2.2
: Because the board lacks hardware interrupts, you must use a software interrupt library PciManager ) to read encoder signals. Encoder Connection HMBGC V2
: Be aware of potential back-feed from USB 5V to the motor power rail; it is safer to power the board via the battery terminal during tuning. Pros and Cons Extremely low cost (~10€ to 20€) No SPI support for magnetic sensors Integrated high-current MOS tubes Limited 8-bit processing power Compact footprint (approx. 50g weight) Lacks hardware interrupt pins for encoders Arduino code template for configuring this board with the SimpleFOC library?
