Re: Power Blue Pill and Maple Mini from external 3.3 source?

I have a blue pill working 24/7 with external 3.3V supply since 6 months, with the on-board 5V->3.3V regulator.
And it still works...

Re: CAN Bus Library for STM32F103

Hm, I only had a short look into the PR, it seems to have changes really deep in the well optimized USB CDC part.
I am not happy to see this, I rate the risk to something go wrong on serial USB quite high.

Re: Couldn't find the DFU device: [1EAF:0003]

It is a good practice to search the forum before you post something.
Maybe this will help you out: viewtopic.php?f=39&t=2663

Re: [libmaple] Black F407VET6

Oh well, I see your point, there are many places which use ADC as a pointer and not as the structure address.
The ideal solution would be to change the ADC module of F4 to be compatible with F1.
Till then, you can replace ADCx by (&ADCx).

Re: [libmaple] Black F407VET6

I think for F4 you have to use: adc_set_sample_rate(&ADC1, ADC_SMPR_1_5); because ADC1 is not a pointer but the ADC1 device structure. So you have to pass its address, that is why &ADC. For F1 is different because the F1 ADC structure includes ISR handlers which are not constant. However, please not...

Re: [libmaple] FSMC LCD 16bit

Nice, thanks for letting me know.
Then I suggest to use this.

EDIT
I modified the lib to get rid of compiler warnings, find attached here.
Place it under Arduino_STM32/STM32F4/libraries.

Re: [libmaple] FSMC LCD 16bit

My local Adafruit_GFX version is dated April 2017, so it may happen that they changed something since then. Could any of you try to copy the Adafruit_GFX_AS lib from F1 to F4 lib directory? Then replace in the 16 bit lib header file #include <Adafruit_GFX.h> by #include <Adafruit_GFX_AS.h> and tell ...

Copy wiring_private.h to Adafruit-GFX-Library folder
Wait, this is not needed. For me, it works without this step.
