Re: constant ADC Average via DMA
DMA cannot do average, it just saves values in an array or one variable.
If you want average of some values that would inevitably involve CPU processing either in an ISR or on main level.

Re: [SOLVED] Maple_Upload.bat : EXCEPTION_ACCESS_VIOLATION
I think the main issue is to find a universal tool which instantiate the USB DFU interface on all OS which allows the upload.
And Java is the one which can be used independent on the platform. Unless one develop different tools for each platform in part.

Re: [SOLVED] Maple_Upload.bat : EXCEPTION_ACCESS_VIOLATION
The main development target IDE is Arduino.
If Arduino IDE changes the behavior, then this will be also adapted, but other IDEs will not be taken into account.
You cannot support every kind of specific behavior for every IDE.

Re: How to measure the duty-cycle of an signal?
Which resolution you want to achieve?
If not critical then you can make it without any specific timer, just user micros() for time measurement.
In this case, taking into account other system interrupts like systick and USB (if you use it) you better use median instead of mean of the values.

Re: Problems with the blue pill and a LCD 16x2
And which core?
If you don't know, then post a picture of the selected board in Arduino IDE.
Please also post a link to the library.

Re: How to start? Connection issue with Bluepill
You have to install the serial driver from ST: https://www.st.com/en/development-tools/stsw-stm32102.html This will allow you to use the USB as serial port. To program the board you need either an STLink probe or you have to install a bootloader (for this you need anyway an STLink first...). Please ...

Re: Interruptions conflict stm32f103RB6T
Please post an example sketch which shows the problem.
In general, there can be only 16 bits of any port associated with an interrupt.
For example: if you have an interrupt activated on PA8, this will share the same interrupt on PB8 or PC8 or PD8.

Re: Buttons problem
For your information, I also needed in one project a button library and decided to use the button library you mentioned because it has callbacks for each event. But it did not worked as I wanted to, in particular it had large time delay to detect a click event. So I decided to make some changes to i...
