Re: Hello from Norway

Ok..

I cant keep uo with the number of STM32 boards that are available. ;-)
I suspect there are hundreds of different types available, all different shapes and sizes.

Re: MapleMini : Standalone Bootloading and USB/Serial Usage

The bat files take multiple paramaters The easiest way to figure out what is passed to them, is to comment out the line at the top that disables echo Then add some echo statements to sprit out the args that are passed. then run the ide, make sure verbose is turned on in the preferences, do an upload...

Blacksphere do support via their Gitter chatroom, and via github issues.

You should post your question there

Re: Suggest having BluePill pins defined for all Arduino pins

Not going to happen... Blue Pill has Pxx pin labels on its silk screen, not Arduino pin numbers. Also... There are hundreds of different STM32 boards, all with different arrangements of pins, hardly end of them have a make or part number on them to differentiate what they are. Boards also constantly...

Re: Timer and Interrupt used together to leave sleep mode

Thanks E. It did cross my mind that the OP may have been using the MM and I didnt think it had the external 32 khz crystal. Using the LSI is an interesting work around, but I have not tried it, and of course the timing is going to me inaccurate unless you apply some calibration in the code e.g. I kn...

Re: Hello from Norway

These boards seem to evolve all the time, and there are clones of various boards.

e.g. The blue pill now has a much more robust micro usb connector.
There is also a clone or variant of the blue pill with only 1 jump link ( on boot0)

Perhaps the Black Pill has evolved

Re: Hello from Norway

Wel... I don't find it a problem

It probably depends on your PC, and also what sort of USB cables you use etc

Technically the value is completely wrong.

Its supposed to be 1.5k to 3.3V, but the board has either 4.7k or 10k to 5V

Re: Hello from Norway

You may not need to solder the resistor for USB

It usually works OK with most PC's even though the value is wrong
