STM Firmware Libraries
STM Firmware Libraries
- For develop a new SW must be used CUBE package.
- The CUBE library for STM32L0 is here.
- STM32L0xx ultra-low power features overview
- How to take full advantage of the low-power UART in the STM32L0
Equipped with a low-power UART (LPUART), STM32L0 MCUs enable your application to stay connected at outstandingly low consumption levels.
The LPUART can run on a low-power clock while the device is in a power-saving mode and wake up the system upon a received frame event or an address match.
To support engineers in squeezing the last nanoampere out of their designs, a new application note (AN4635) is available which – complemented by the X-CUBE-LPUART software examples – guides you towards the optimum use of the LPUART with the help of numerous case studies.
