STM32 Cube library - CMSIS and HAL for F0, F4, F7, H7, L0, L4 and WB microcontrollers
|
||
|
|
=====================================================================================
|
||
|
|
|
||
|
|
This repository contains a copy of STMicroelectronic's STM32 Cube firmware
|
||
|
|
library, with CMSIS-device and HAL code for STM32F0xx, STM32F4xx, STM32F7xx,
|
||
|
|
STM32H7xx, STM32L0xx, STM32L4xx and STM32WBxx microcontrollers. Minor changes
|
||
|
|
are applied to the HAL source to support MicroPython's port to the STM32.
|
||
|
|
|
||
|
|
The "vendor" branch contains the original sources and is updated from
|
||
|
|
time-to-time when new versions become available. The upstream sources are
|
||
|
|
provided as separate releases (and in separate archives) for each
|
||
|
|
microcontroller class (eg F4, F7, L4). These are merged together here in
|
||
|
|
the "vendor" branch, because the idea of the HAL code is that it provides a
|
||
|
|
uniform interface to all microcontroller classes. The commits in the "vendor"
|
||
|
|
branch are tagged as appropriate with a tag that describes all the available
|
||
|
|
versions at that commit, for example F4-1.5.0+F7-1.1.0+L4-1.3.0.
|
||
|
|
|
||
|
|
There are then working branches that branch at a given vendor tag and apply
|
||
|
|
minor patches to the vendor code, for example work-F4-1.5.0+F7-1.1.0+L4-1.3.0.
|
||
|
|
The patches/commits that form a given working branch are reapplied (with
|
||
|
|
conflict resolution) to newer vendor tags to create the next working branch.
|
||
|
|
|
||

|
Original sources
|
||
|
|
================
|
||
|
|
|
||
|
|
The sources are obtained from ``http://st.com``
|
||
|
|
|
||
|
|
For all .c and .h files the following processing has been done to the original
|
||
|
|
files before committing them here:
|
||
|
|
- lines endings changed to unix style
|
||
|
|
- trailing spaces removed
|
||
|
|
- tabs expanded to 4 spaces
|
||
|
|
- non-ASCII chars converted to their ASCII equivalent
|
||
|
|
|
||
|
|
A shell function to do this processing is:
|
||
|
|
```sh
|
||
|
|
function clean_code() {
|
||
|
|
chmod 644 $1
|
||
|
|
cat $1 | awk "{sub(/[\t ]*\r/,\"\")}1" | expand -t 4 | tr \\200\\205\\211\\221\\222\\223\\224\\226\\231\\244\\261\\265\\302\\327\\342 \'??\'\'\"\"\\-\'??u?x\' > tmp$$
|
||
|
|
mv tmp$$ $1
|
||
|
|
}
|
||
|
|
find path -type f | while read file; do echo "$file"; clean_code "$file"; done
|
||
|
|
```
|
||
|
|
|
||
|
|
Directories from the original sources are mapped into this repository according
|
||
|
|
to the following:
|
||
|
|
```
|
||
|
|
Drivers/STM32F4xx_HAL_Driver/Inc -> STM32F4xx_HAL_Driver/Inc
|
||
|
|
Drivers/STM32F4xx_HAL_Driver/Src -> STM32F4xx_HAL_Driver/Src
|
||
|
|
Drivers/CMSIS/Device/ST/STM32F4xx/Include -> CMSIS/STM32F4xx/Include
|
||
|
|
Drivers/CMSIS/Device/ST/STM32F4xx/Source -> CMSIS/STM32F4xx/Source
|
||
|
|
```
|
||
|
|
And similar for the other microcontroller classes.
