New "Getting Started with Blue Pill Tutorial Video"

While I watching youtube, I got this suggestion for a video: http://educ8s.tv/stm32-tutorial/ The presenter does a great job of describing how to use the Blue Pill with just an FTDI dongle (actually any USB serial dongle but he uses the FTDI). It is just a short video but he does a great job describ...

Re: CPLD Fun Board (Arduino STM32 + Altera CPLD)

Regarding examples, I had noticed this Altera Application note:

"AN 265: Using Altera MAX Series as Microcontroller I/O Expanders"

I was selfishly hoping you had already written the mcu code for the STM32 : )

Looks great! Do you have example VHDL code that interfaces the CPLD and the stm32?

Re: Hello from California

Just wondering if anyone has jumped over this hurtle and might want to share a solution. funny you should ask, just the other day I configured platform.txt and boards.txt to use openocd as an SWD programmer using the bcm2836 pins. I didn't think anyone else cared so I didn't post about it. If there...

Re: A faster ringbuffer implementation

Is that just ensuring that the structure is initialised to 0 when it is created? Yes. However this is only a problem if it instanced on the stack. If you make it a global variable the .bss section gets zeroed out at startup. Also, why is the capacity one less than the actual size of the buffer? I l...

Never the less, this looks like an improved version of the BluePill. Its just a shame they didnt use a different pcb colour e.g. green etc
Have you looked at their website? Black is their thing, all their boards are black.

http://www.robotdyn.com/ ... lots of black there.
