In this way we have more design choice by taking advantage from the STM32 portfolio.

The framework has been tested on a NUCLEO-L073RZ board.

It is interesting to give a look at the difference between the L4 and L0 source code of the simple demo displayed in the following image.

ODeV - diff between STM32L4 and STM32L0 port.

The first things we observe are the modification in the Kernel layer:

The STM32Lx-HAL library is changed from L4 to L0

The CMSIS files are changed from L4 to L0

The FreeRTOS portable layer is changed from ARM_CM4F to ARM_CM0

All these changes are a simple copy paste of the new files after deleting the old ones. Of course we need to change some project settings.
We also need to change the linker script. Except this, there are very few files, at application level, and a couple of files at the service layer (these are the files xxx_mx.c) that we need to modify or change.

That is all. Now we can reuse all the Managed Task we developed for STM32L4 also with STM32L0.

The source code is available in the master_l0 branch of the GIT repository.
