Programming

To program with the USB-C connector you need to hold down the button on the ACB while powering it up. This will put the STM32 into DFU mode where you can program it directly with the Arduino IDE (or other software of your choice). It’s also possible to flash the board using the OpenActuator GUI from the tools menu and selecting a precompiled binary. ACB button You can find the open source software in the acb-v2.0 repo and edit the source in src/. When editing the firmware there is potential to cause damage to either the ACB, your motor, or power supply, as there’s high current MOSFETs on the ACB. I reccomend using a current limiting PSU when testing. Find more instructions and the future roadmap for the ACB firmware
