... and if we receive fakes, just make a complain to the vendor ( perhaps air them here ). ... I really think that using this forum to air grievances is not a good idea. Making a concise statement along the line, "Ordered n bluepills and received x bad/defective/not-as-advertised boards; filed a co...

Re: Blue pill current usage

Does anyone have any rough figures on the amount of current a blue pill uses when running without any power saving modes? I am wondering how many I can safely run off a single 500ma supply. Thoughts for non-PC port power: Is the 500mA rated PS a wall-wart or batteries, if batteries, alkaline or lit...

Re: Correct usage of HAL functions in Arduino code

... The ages when you can spend years for engineering gone. Everything is processing faster and faster. If you are slow - you are out of your business. That is why developers use more and more high level of development. And that is why waterfall is used only at the construction yards. Agile, CI/CD ...

Re: MIDI Class Compliance

Thanks! Yeah I’ve got a program I’ve been working on, on my mega but wanted the processing power of the STM32, Do you need the extra clock cycles and efficiency of the STM32? My experience last year with the Mega2560 is that even at 16MHz, the board is quiet the powerhouse. An entire Rotax engine m...

Re: Correct usage of HAL functions in Arduino code

@mrburnette Don't agree with your option, here are my thoughts: ... At my current development I have to move from AVR platform (two different chips, not ATMEGA328) to STM32 (and here I had to switch to more advanced chip during development). PS. Sorry for the flame :) I expected flames, but that is...

Re: MIDI Class Compliance

There is already a request in github to port MIDI into the official core.

Issue #668

For the future, an easy way to query google is like below:

"midi" site:github.com/stm32duino
