Re: Hello from California

BTW.
You can get the BluePill boards for a little over $2 USD

Teensy is great, very fast and professional support from Paul, but if you dont need that level of performance the BluePill etc are IMHO the best bang per buck.

Re: Funny Package

I thought some Black Pill's (non robo dyn) had the LED on another pin.

Its good that the robo dyn version has it on the same pin as the Blue Pill.

Re: Hello from California

I presumed that the main problem was the ARM compiler, but I presume that the tools binaries would also be incorrect and need to be recompiled from source for RPi as its an ARM board

Re: Funny Package

Cool

Looks like the robot dyn is probably the better of the BP boards.

Which pin is the LED ?

Re: CAN Bus Library for STM32F103

I think I have a CAN compass from a DJI drone, but I've no idea exactly what type it is (and I'll have to find where I put it, as I removed it from the drone in order to fit a non CAN compass to make it compatible with a non-DJI flight controller) So.. Until I find it, I would not be able to test th...

Re: Hello from California

It may be worth PM'ing @tekk, as its his PR and he (or she) may be able to help you with it. @tekk posted several times about this http://www.stm32duino.com/search.php?author_id=152&sr=posts But I would generally agree, that running Linux e,g on an old laptop is probably going to be the best option

Re: F405 & F411 versions of the BluePill

@racemanic OK. I'm not trying to go ultra cheap, but from what I've seen, the members of the forum are very price sensitive. I guess we need to have a total BOM cost and work out the percentage of cost for each item, to see if any particular item is substantial part of the overall cost and if so, wh...

Re: Hello from California

You may be able to use the LibMaple based core.

Someone submitted a PR for RPi support, but I have not merged it to Master as it added a huge bulk of files that 99.9% of people would not use.

However you could clone the Arduino_STM32 core to you RPi then pull and merge that PR locally

Re: F405 & F411 versions of the BluePill

Do both regulators have the same package / footprint?

IMHO if you want to run from Lipo, you should use an external power management board which also handles not totally discharging the Lipo

I think you are in danger of over speccing and making the price uncompetative
