Any chance to add the Pro Micro Board to OSX in the near future ?

[Thomas66]

Hello,

since there is not much different (compared to weight and size) between the Arduino Pro mini 3.3V/8MHz Board and the Sparkfun Pro Micro 3.3V/8MHz board , except the Pro Micro is much easier to handle because of its USB Port , I was wondering if there is a chance that it will be integrated into OSX in the near future ?

I already tried the Pro Micro - ATmega32U4 (for a simple Multiplex Vario) but its actually not working with openXsensor V8.0.1 / Arduino IDE 1.8.13 .
(Attached : File with compiler errors )

For me it looks like there is some code implemented which only works with AVR based boards - especially interrupt stuff like PCMSK2 and other things...

Hi Thomas.

Did you see this post here?

Cappy used a 32U4 and mstrens (the oXs developer) answered that.

Mstrens is not answering in this forum at the moment, maybe he is on holiday. Hopefully he does not have to fight Corona.

For testing use a Uno or Nano and, when you are satisfied, flashing a Pro mini it’s not rocket science

I would like to see it on the STM32F103 based Blue.Pill board.
It is great, fast, lots of memory, and it costs next to nothing.

Hi João.

Would prefer the Maple Mini (left one). But the size compared to the Pro mini!

The one on the right, that is NOT a genuine Pro mini, but has a LGT8F328P. A bit faster than the original 328, End of the year I am going to do some tests with oXs on those.

The maple mini and the Blue Pill use basically the same processor. Well, the Blue Pill is supposed to have an STM32F103C8, but despite being marked like this, it actually has an F103CB version that has 128kb flash. The same as the Maple Mini. I know because in some projects I use much more flash memory than the 64Kb it is supposed to have.. And the code fits..
You can't compare the Pro-Mini with these beasts [emoji14] even if it has a slightly faster m328 processor. It will never reach the 72Mhz of the STM32 chip.

The C8s (which are really what's on the blue pill) are basically CBs that have a defect in one half of the flash, and are thus sold as 64k.
You can flash a bigger image but it can have unpredicatable results. Happened to a few people who DIYed multiprotocols lately and had crashes because of that. Don't exceed the 64k on anything important.

[jhsa]

Funny, I have projects using 98% of the 128K flash memory and they work well.

But I have also encontered a couple.chips that do not work on these same projects.
I thought it was because of fake chips, not defective ones

João

Yeah it might work or not... Some may have an outright faulty flash cell, but some might only fail in certain temperature/supply voltage conditions that makes them still work sometimes, but not across all the specced ranges.

@Kalle,

for some reason I missed that post.. mea culpa

The main reason I am not that happy with the Pro Mini board is, that the upload over a USB-TTL converter may or may not work.

One shouldn't expect all are electronic experts, also some Pro Mini boards on the market have wrong/ reversed pins, some USB-TTL converters causing problems uploading while a sensor is already connected .... There are tons of error sources doing it like this way . just google für a.e. :

avrdude: stk500_recv(): programmer is not responding



Just my 5 cents

Thomas, then use a Nano

cu KH

[jhsa]

Yep, a Nano is just a Pro-Mini with an onboard USB adapter.

João

[kalle123]

Yes, but the Nano is bigger, just like the blue pill ...

AND I DON'T HAVE THAT MUCH SPACE

[Thomas66]

As far as I know there is no very small 3.3V board with USB but the Pro Micro. That's the reason I was asking this...

On the other hand I am not sure if it would be critical or not to use the 5V data / signal line (from a nano) to the 3.3 V data / signal line of the receiver.

Which RX please?

I didn't say it shouldn't be ported to the Pro-Micro.. I just said I would like to see it on the Blue Pill also. If ported to both, even better. It gives more possibilities.
