The ZeST software algorithm for STM32 allows sensorless motor drives to achieve full torque at zero speed. This innovation enables smooth and predictable motor control in general-purpose drives.      Applications such as power tools, domestic appliances, and e-bikes require motors that can start quickly and with maximum torque. Traditional sensorless drives are unable to meet these demands as they cannot detect rotor position when stationary. The STM32 ZeST algorithm offers a solution that enables optimal sensorless control for any permanent magnet synchronous motor (PMSM) at zero speed, working in conjunction with the high-sensitivity observer (HSO) algorithm. This embedded software solution operates seamlessly without the need for extra hardware or special features in the microcontroller, and it dynamically estimates motor resistance for efficient control. The STM32 ZeST and HSO algorithms not only improve energy efficiency by reducing peak current during startup but also lower the b

Clang/LLVM toolchain project overview For over a decade ST has offered GNU tools for STM32 as the free, reference toolchain when developing STM32 applications. It is well supported across the complete STM32Cube ecosystem and will continue to be maintained by ST. The Clang/LLVM toolchain will over time offer STM32 developers better code density and execution speed. This release is a first step on the journey towards better toolchain performance and increased STM32Cube ecosystem integration. The toolchain will be supported within STM32CubeMX and with STM32Cube for Visual Studio Code. This release provides a first version of the ST Arm Clang toolchain built on the Arm LLVM source tree. It allows early adopters to try a toolchain with a similar performance compared to today’s GCC. It offers more sanity checkers, more optimized C libraries, while compiler benchmark figures will come later. Further to this initial release, developers can expect two additional steps: Feedback collection   Ear
