精选 视频
Discover the large and pin-to-pin compatible STM32 ultra-low-power portfolio. This offer covers more than 2 billion of applications like IoT, Industrial sensors, wearables & home automation.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
Getting started with STM32L1
- Purchase a 64-pin Nucleo board, Discovery kit or Evaluation kit for STM32L1 MCUs.
- Download the Free STM32CubeL1 embedded software package containing the HAL, LL (low-layer) APIs, and middleware. Then install ST’s Free STM32CubeMX graphical software configuration tool that supports pinout configuration, code generation and a power consumption calculator. Start with one of the many examples provided or build your own project.
STM32L1 Low power Wireless Solution (Sigfox)
To discover low-power wireless solutions based on the STM32L1, the STEVAL-FKI433V1 (430 – 470 MHz) and the STEVAL-FKI868V1 (860 - 940 MHz) development kit based on Spirit2 low-power Sub-GHz transceiver are now available.
