Arduino for STM32

Well, WeAct liked it enough to pull it into their repository. However, I haven't tested everything or verified 100%. I do think I did a pretty thorough job for putting the 2-3 documents together to make the pinout chart. There may be missing information, but I'm reasonably certain the information th...

D'0h! I feel the dumb now.

Maybe you could consider using CAN between the master and the slave. This is a neat solution, very flexible, and very robust. Lines may be very long (100 m or more) without communication errors, unlike I2C that cannot allow more than say one metre. Does F103 have native CANBUS, or software controll...

Can you please post a link to this? I could not find it.

I've updated my original post. Thanks so much. So, the DFU is on the stm chip itself? And the HID (ST-LINK) and STMduino are _software_ flash loaders, correct? Only one can be installed at a time, correct? If using the Arduino IDE, I'd probably be better off with STMduino, correct? And to flash eith...

Ok... I'm a bit confused as to the differences in these STM32-F411 bootloaders (similar for F401). * (Hardware) STM32 BOOTLOADER [dfu] (pre-installed on stm32 chip) [available after holding KEY for 1/2 second and releasing] [USB] *STM32 HID Bootloader (pre-installed) [default bootloader] [ST-LINK?] ...

I hope it's useful! Please let me know if I have mis-labeled or forgotten something!

Heh... These boards aren't the easiest to use, are they? The Teensy 3.2 spoiled me! I've already managed to accidentally wipe the HID Bootloader and Bootloader from the F411! I'll just have to wait for the STLink adapter to come so I can put them back on! No idea why USB programming isn't default!

Don't know if it will help, but I just made a first draft PDF of a pin layout for the F401/F411.
