SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.

Energy Efficency of STM32 Libraries

Posted by carbonefabio on 2016-09-09 15:32

I am going to program STM32L1 micro for a low power / energy harvesting application.

I have tried both SPL and HAL library.

Apart the well know pros and cons, what do you think is better for energy efficency and energy saving?

Can this choice (with the same funcionality of code) affect the global consuption?

Thank you

I do test with low power on L1 and L4,

I stest only SPL, by with this library i get 30% bigger power consupton.

For much biigger power efficiency write register based software.
