BMP Windows drivers missing digital signature

Dears, I tried searching the site but couldn't find a solution: I set up a BMP blue pill and I'm trying to use it on a Windows 8.1 machine. When I plug in the BMP blue pill in my machine I can see the corresponding entries in the device manager with an exclamation mark stating a driver is required. ...

Re: Maple Mini clone/BluePill differences?

One claims to have a STM32F103RCB8 but the F103RC is physically bigger, and probably would not fit on a board of that size, and the photos look identical If you look through all the MM links you'll notice almost all claim using STM32F103RCBT6 which is a clear nonsense. That name anyway comes direct...

Re: Maple Mini clone/BluePill differences?

bluepill features i like: o If you use an stlink/bmp programmer, it has easier access to the swd pins o the 5v is available on a pin o I like paying for 64k and getting 128 o I can get them from ebay, for the Baite maple mini I have to go to aliexpress You can find Baite MM also from ebay, maybe li...

Re: Arduino read/write funtions "slow"?

I don't know if the AVR chipset has the equivalent of the BSSR (I didnt think so, but I could be wrong) In truth AVR has an even smarter solution from my point of view, you can set: PIN<port>=<pin_mask> and this toggles those pins where <pin_mask> is 1 leaving the others unchanged. So you can blink...

Re: pinMode() disables timer even if no PWM mode involved

edogaldo, can you please detail which things exactly get broken with this PR? Hi Steve, I'm in doubt with this part: } else { // disable channel output in non pwm-Mode timer_cc_disable(PIN_MAP[pin].timer_device, PIN_MAP[pin].timer_channel); } A question as I'm not that expert with timers: can't we ...

Re: pinMode() disables timer even if no PWM mode involved

Can a PR be generated for just the pinMode change Hi Roger, there is PR #288 which addresses it but I don't understand why the guy added a second commit which, on my opinion, breaks things again.. I think the 1st commit only is ok (there's just the need to also modify the commit which still talks a...

Re: Set flash wait states based on CPU frequency

Hi Roger, just a note: in the PR assumption is to use HSI for 8MHz, not HSE.

The stm32flash loader relies on python, correct? Which version of python are yoy using? Afaik the flash loader is compatible with v2.6 but not with v3
I had a similar issue running the loader with python v3

Re: Problem with receiving infrared remote control codes

there is some discussion here http://www.stm32duino.com/viewtopic.php?f=3&t=2091 about the uart ring buffer, which apparently stalls if some of the ring buffer variables is not declared as volatile. you may want to try those fixes if it relates to usb - serial stalls, i'm not too sure if that ring ...
