Re: How do I get my AWU ISR into the interrupt vector table?

@Pito I'm not sure we're using the same hardware platform. I don't seem to have memory at those addresses. I can't find any mention of SCB anything or VTOR either. Grep doesn't show any matches in the entire package. @Jimmus - You could well be correct, what hardware platform are you using, and whi...

Re: Complete dashboard for an old car

@ahull presumably using low power mode will require a psu that can work with such a low power draw... ie the OP needs to be careful what he chooses if he goes down this route. That's a good point. Things like powerbanks give up and cut the power when the current draw goes below a certain level, so ...

Re: Did I get a junk blue pill batch?

Perhaps some variants of this package include the load capacitors. One of the suppliers I looked at states "Package: Ceramic resonators come with standard, single-in-line package (ZTA, ZTB and ZTT), or 3-leads with built-in capacitors (ZTTS, ZTTCV)." , so I suspect this particular device comes in di...

Re: Did I get a junk blue pill batch?

Well spotted. I'm surprised the manufacturer didn't make these devices with no particular orientation since they only have two active pins do they not? It seems that for some reason they put a two pin device in a four pin can... Example => http://www.chinafronter.com/wp-content/uploads/2013/05/SMD12...

Re: Metal detector dc42 improvment

I've not had much time to look in to metal detecting with the bluepill, however I suspect with a little effort, it would make a good "brain" for a pulse induction type metal detector . On the subject of audio amplifiers to drive the coil, of an induction balance detector, I did wonder if one of thos...

Re: Hello from UK

change the ebay.com/blah url to ebay.co.uk/blah, You can also find the ebay item number (top right corner in the description tab) and insert it into the search bar. That also works... most of the time. Not sure if the ebay search is at fault, but I find the url trick more reliable. Sometimes the se...

Re: Hello from UK

The "dollar for pound" tax has existed for years, if you look at a typical tech item on ebay.co.uk and compare with ebay.com you find that if it costs $100 in the US, it will cost £100 in the UK. This situation has existed for years. My techniques if buying cheap stuff from China on ebay is to find ...
