BLHeli_32 Firmware, Arm 32bit MCU, Dshot1200
BLHeli_32 is the third generation BLHeli code, following base BLHeli and BLHeli_S.
BLHeli_32 runs on an ARM 32bit MCU, initially it will be on a Cortex-M0 running at 48MHz, but there are MCUs out there that can run a lot faster.
So what can the increased MCU speed do?
First of all, it can run input signals with lower latency at faster rates.
Dshot up to at least Dshot1200, and at rates up to at least 32kHz is now supported.
Secondly it allows packing of more functionality.
• Programmable pwm frequency, up to 48kHz, that can run motors even smoother, and also
allows for moving of small but potentially disturbing humps in the throttle response. All ESCs
have these bumps, with BLHeli_32 they can now be moved in the rpm range, to a place where the
system has low sensitivity to them.
• Auto timing. Which is not the option to choose if you’re after max power. But if you want the most efficient running with very good robustness against desync, it is the perfect choice.
• Programmable brake on stop force. Which allows control of the braking of fixed wing props.
• Improved direction change in bidirectional mode.

Rc-toys Multi Rotor safty Tip Keep your PROPS OFF not installed until you are fully conversant/understand in full the functions of your Tx in full including TRAV (end Points), the arm and disarm procedures - realise that for a noob skiping or out-of-order set-up steps or moving sticks, or even static - PROPS may start at anytime without warning. Never install props prior to calibration of the ESC and testing the gyro orientation, and arm/disarm testing of the board - YOU are responsible - make sure your actions and your Copter is safe. Never ASSUME the props will not start - removing the props removes the risk.
