Arduino for STM32

Hi,

Unfortunately, I’m on Mac, so no idea how the windows side works. Might be best to start your own thread!

Hope it works out!

Cheers,

Hello,
I am having same problem eg no usb connect from WeAct F411CE to Win10 64 Device Manager does not show the board COM port.
I have a STLINK and ...

Don't mind me being an idiot...

I hadn't added the build_flags to enable the USB serial in PlatformIO


[env:blackpill_f401cc]
platform = ststm32
board = blackpill_f401cc
framework = arduino
upload_protocol = dfu
build_flags =
-D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC
-D USBCON


All I needed was ...

So,

I'm just getting started with the BlackPill (F401CC) uploading with the DFU through VSCode/PlatformIO with ST STM32 14.2.0 (and before I had 12.something, updated it to see if that was the issues). It's a knock off WeAct v2.0, and came with the original pulsing blink.

I can upload to it with ...

Old Site search should cover old stuff for BluePill, etc.

Oh thank you MrBrunette!

I think I saw something from one of those links ...

Hey guys!

Looking for some pointers regarding possibly implementing USBMIDI on a bluepill (F103), and later one of the new blackpill's (F401) when I get round to it.

Background: I've made a little 8 note wavetable poly synth, with envelopes, LFO and an arp, which is a lot of fun! Buttt, I'm yet to ...

There is a section dedicated for STM8: https://www.stm32duino.com/viewforum.php?f=75
With F401 you can do same (and more) as you want with F103.


Thanks Steve! I’ll have a play with them and post any stuff there.

As for the F401’s they’re probably more suited to my project to be honest ...

So, I was happy this morning as my long awaited AliExpress order turned up...

Turned out, the seller sent 10x STM8S105 black boards, instead of 10x Blue Pills (STM32F103). :oops:

Super annoying, definitely my fault for ordering too cheap (I got excited as they were the oldish price of £1.80~ a ...

AnalogRead is arduino compatible, so it is limited to 0-1023 by default. You can change this to 12 bits, 0-4095 by adding a line or two of code to your program.

See https://github.com/stm32duino/wiki/wiki/API#analog


Thanks Fredbox, I tried this, but unfortunately the same thing happens with ...

When I poll them, I’m getting 0-1023 (10bit) which is fine for my use, but the upper range (roughly the last 1/4) are all responding 1023.


Are those pots linear or logarithmic ??


They're linear, when situated in the centre they're reading ~1.65V. and I'm getting a correct reading with the ...

I might be off on my thinking it was down to a Voltage Ref setting then. :roll:.

I have 3 potentiometers (10k) wired up to pins PA0-PA2 (along with GND and 3.3V provided via a 3.3V LDO that’s one of 2 powered from one of the 5V pins).

When I poll them, I’m getting 0-1023 (10bit) which is fine for ...
