BLHELI32 is the newer and improved version (generation 3 of the BLHELI firmware - after BLHELI and BLHELIS) utilizing 32 bit processors on the ESC. The main job of ESC firmware is to control the speed of your motor and thus the timing for switching the motors phases. In this article we will discuss major differences between the new BLHELI32 and the.

The BLHeli developers have released the new code and added the S to set it apart from the base code, the S represents something special. the next generation of ESC firmware. But what makes BLHeli__S firmware so special and is it worth upgrading yet? And will it actually make a difference to your multirotor flight performance? Read more to find out.

Key features of BLHeli_S

Hardware PWM – smoother and more responsive motor response
Always use damped light (Regenerative Breaking) for better multicopter control
Code supports sync loss prevention – tuneable parameters to make your ESC work well in the most demanding applications (not just FPV racing)
High resolution throttle steps
Supports Oneshot125 (125-250us), Oneshot42 (41.7-83.3us), Multishot (5-25us) protocols
Automatically detects input signal protocol on ESC power up
Beacon Function – your ESC will start beeping after a set time of zero throttle to help you find your quadcopter.

Why is hardware PWM better?

Since the initial release of BLHeli, hardware has improved so the new code is designed to take advantage of the new hardware improvements with the most signification being hardware generated PWM which gives much better performance. This is the most noticeable improvement of BLHeli_S as your motors run smoother, quieter and are technically more responsive too.

Trending

Because the hardware generated PWM signal is synchronized with the micro controller clock on the ESC, the motors run more silently and efficiently (with less high pitch squeal). This also enables much more precise throttle steps depending on the ESC hardware (micro-controller and PWM driver type), however the range is between 512 steps and as much as 2048 steps with high end ESC’s.

The hardware PWM also allows you to control very high speed motors (up to 500k eRPM with some hardware). With the older BLHeli firmware and software PWM, the maximum speed signals can be sent to the motor was 16Khz. With the hardware PWM, your ESC can send signals at about 36Khz which is rather insane. Because your motors are getting updates much faster the control is much more precise and smoother response.

Are 32 bit ESC any better?

Many of the new BLHeli_S esc’s coming to the marker actually use a 32bit processor. This means that each ESC has alot more processing power to do more advanced stuff. Currently most of the 8 bit ESC’s running BLheli are still not reaching the processing capacity so why have the developers started using 32 bit microcontrollers on the ESC’s?

The main reason is because 32bit ESC’s are easier to program, the 8bit code is written in C and Assembly (can be a real pain to work with), but the 32 bit allows programming in C++ which is abit easier. This means that this combination of easier programming language and more processing power will make adding novel features abit easier.

Can I upgrade my BLHeli ESC to use BLHeli_S?

No, this is not currently possible as BLHeli_S is designed to run on new ESC hardware, to take advantage of the hardware PWM driver. Current ESC’s that run BLHeli use software PWM and do not have a dedicated hardware PWM driver so they cant use BLHeli S.

Conclusions

When you first turn on your motors with BLHeli_S ESC’s you will notice how smooth and quiet they run, but for me that is where the differences end. With the current BLHeli S ESCs on the market they dont translate into additional performance on static thrust tests compared to some of the other leading ESC such as DYS XM ESC series. Ucec video capture software download mac. I know DYS are releasing some new ESC’s to support BLHeli S called the XS series.

Once you are up in the air flying I could not tell any difference in performance. It is worth noting that I am not exactly the best FPV pilot you can just about manage the odd flip in a wide open area. So perhaps more experienced racing pilots will be able to feel the improvements (let me know). The active breaking definitely improves the responsiveness of your quad, but that is an also option with regular BLHeli ESCs.

At the end of the day I would say its probably not worth ripping out your BLHeli ESC’s just yet, but if you are building a new quad then its a good idea to get some BLHeli_S ESC’s since I am certain we will see some novel features added to the BLHeli code in the near future.

If you have any experience with the new firmware and ESC’s or comments please let us know below!

New version naming convention

The new BLheli S firmware will have the naming convention of A_L_10_REV16_0.HEX

The first letter denotes the pinout of the Micro controller (MCU) on the ESC. Currently A,B,C,D,E,F,G
The second letter is the MCU clock speed. L for 24MHz, H for 48Mhz
The two numbers denote the MOSFET switching deadtime, if the FET has adaptive switching then 00 is used
The REV is the actual code version, the bigger the number the more recent the code is.

BLHELI is a firmware for ESC's. BLHELI_32 is the newer and improved version (generation 3 of the BLHELI firmware - after BLHELI and BLHELI_S) utilizing 32 bit processors on the ESC. The main job of ESC firmware is to control the speed of your motor and thus the timing for switching the motors phases. In this article we will discuss major differences between the new BLHELI_32 and the predecessor BLHELI_S.

So how do those firmwares differ in functionality?

One of the main factors is the protocols the ESC supports in order for the flight controller to communicate with it. Nowadays this communication is mostly digital and in many cases it is one form of Dshot.

The difference between Dshot versions is the amount of time it takes for one data packet to be sent from the flight controller to the ESC. This means, the higher the Dshot number the faster you can transmit data from your flight controller to your ESC, the more responsive your quadcopter is. If you can actually feel the difference between, for example, Dshot 600 and Dshot 1200 is up to your pilot skills and how used you are to one or the other.

Speed

The difference from Dshot 600 to Dshot 1200 if a factor of about 2, meaning the time it takes to send one data packet on Dshot 1200 only takes have the time that it takes on Dshot 600. On Dshot 600 it takes 26.7us to send one data packet, on Dshot 1200 it only takes 13.4us.

Dshot 1200 is only available on ESC's with BLHELI_32 firmware - so this is the first major difference. Touch base updd crack.

Telemetry

The second major difference is, that BLHELI_32 has telemetry, meaning it can send data back to the flight controller. The ESC can sent metrics like RPM, temperature and current draw back to the flight controller. This enables you to show all those information in your OSD.

Configuration

Further BLHELI_32 may be configured with Dshot commands directly from the flight controller. It also allows current limiting, meaning the current output per ESC may be limited to a certain value.

Open source

Another major difference is that, BLHELI_32 is no longer open source. BLHELI and BLHELI_S were written in assembly language and were open source. The new BLHELI_32 is a complete rewrite in C and ESC manufacturers have to pay a licensing fee to the BLHELI dev
