Dear Thiago,

a lot of my STM32 work has probably not yet got upstream. E.g. there
are python scripts that get pin mapping files from the STM data
base. In the end I use it like e.g.
# warning BAD TIM2_CH1_AF assignment

If you want, I can upload my git tree to my github account. Maybe we
should have a Zoom talk, solve problems when other people use that
You know my definition of program usability:
1. It should work
2. It worked for me
3. It works for me
4 It works

As I did other things the last time, I think the tree is at about
stage 2.5 :-)

Using a single pin designator as "PA00" against  the two
designators PortA and Pin 0 allowed a lot more header and configurator

As I work for several families I use different build approch, only in
user space.
<base firectory>: Containg all the projects and a common makefile to
build the libs 
<project directory>: Containing the user code and the application
<target build directory>: Containing the Makefile
export BOARD ?= $(shell basename $(CURDIR))

include ../../Makefile.lib
and a local build of the directory. A simple make here will build the
application and the code

This results in a tree like

Compiling for another supported STM32 board would mean to only create
and copy the makefile from en_apps/socketserver/nucleo_f767zi/Makefile

Feel free to ask more, but I am mostly on the road this weekend.

Anybody at embedded world in Nürnberg?
