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.
