Arduino for STM32

Check this other project (a classic Arduino one not a STM32F103C Bluepill).
Very easy to do, almost out of the box...

Hello all,

I'm currently rewriting (again) entirely the firmware of a commercial product based on the STM32 platform.
After the Miditech midi interface , this time it's the Midiplus SmartPad, a 60$ clone of the Novation Launchpad :

I use \r to animate the progression bar.

I just published the first release with binaries for Windows and Linux ready to use here :
https://github.com/TheKikGen/stm32-tkg- ... s/tag/V2.3

If anyone want to test it !

I already have this in my code. The \r is not usable at all.

Hi Steve. The IDE pseudo compilation console doesn't display correctly (as the IDE Terminal) most of C escape characters (e.g. \r).
So not possible to show a nice progression bar. The "-ide" option of tkg-flash shows consecutive characters on the same line instead.

Command line ...

Thanks Steve. I will give a try to that...

Other subject :
I have added a new "page offset" option in TKG-Flash CLI. This allows to flash a bin firmware file from any bootloader at the right address.
The stm32duino bootloader flash at FLASH BASE+ 0x2000, last version of HID bootloader flash at ...

Yes !
The Roger's bootloader is very long to start (more than 3 s), especially because USB (CDC) is launched during the boot up sequence (for the DFU mode notably). My first approach was quite similar with HID, but you must first shutdown USB, wait more or less 4 seconds, then start again USB with ...

I reformulate again steve.

(reset)
1. If magic word is here goto UPLOAD (another path) then Reset after flashing
2. Magic word is not here. put Magic Word in DR10
3. wait 2 seconds to let the user a chance to reset and go back to step 1
4. Set DR10 to 0
5. Jump

if the MW is here, no problem, and i ...

The bck register was implemented for sure in my sw from the beginning (i use that even in my other midi sw), but in the classical way, like you mentioned fro the Roger's bootloader and Vassilis.
I'm talking about a trick to get into the bootloader with 2 short consecutives reset, by playing with ...

Sure Steve.
I use backup registers which are preserved after an hardware reset.

1/ First, the bck register DR10 (used by stm32duino) is checked for the magic word, because if already set, we enter directly in bootloader mode
2/ The bckp register is set to the value of the magic word before entering ...
