STM's in the wild

Post by racemaniac » Tue Apr 23, 2019 3:22 pm

Just a fun topic to post where you encountered STM microcontrollers in the wild :)

I just had the control board of my dishwasher replaced, it runs on a quite large STM8 microcontroller,

It's an STM8S207R8T6

A cheap oximeter has an STM32F030C8T6, I wrote a post in the stm32duino forum
http://www.stm32duino.com/viewtopic.php ... 98&p=44243
The Wemos motor shield 1.0 has an STM32F030F4
https://wiki.wemos.cc/products:retired: ... eld_v1.0.0
There is also the firmware source. I have this shield but not tested yet.
The V2.0 version instead the chip is unknown, maybe painted black or erased.

not quite in the wild
but i think the blue pill / maple mini makes a good controller for a mechanical keyboard

Apex M750 recognized as STM32 bootloader

any one has a steelseries keyboard or mouse? i'd guess one'd need to do a teardown and figure out where is that boot0 pin
:D

do you have a steelseries mouse?
https://hackaday.com/2017/07/29/injecti ... next-hack/
The steelseries Sensei mouse was selected for the hack because it has an overpowered mircocontroller: the STM32F103CB. With 128 KB of flash the researchers guessed there would be enough extra room for them to add code.
:D

I have one of those! I have the wireless one and I've actually checked that the MCU on the mouse is not an STM32, but I haven't checked the charging base / receiver.

I wrote before about the Wemos motor shield 1.0 that has an STM32F030F4.
This shield has no firmware installed, I read an italian blog about this.
http://www.mauroalfieri.it/elettronica/ ... pdate.html
I bought this shield and found that the flash was empty. I used the serial bootloader to flash since there are not pins for ST-Link.

So you have to build the original sources or use other modified sources that are around.
