I got tired of twisting DuPont cabels to get from different programmers to different boards.
This is an adapter that lets me connect the programmers I commonly use (Jlink-mini, BMP, STLink clone) with the boards I commonly program with straight through wires. I left a couple unpopulated for future in and out.
Quite a large number of inexpensive nRF51/nRF52832 watches which appear to have already been hacked, documented, and made available for others to now hack too: https://github.com/curtpw/nRF5x-device-reverse-engineering
@NeverDie Nah, I'm fine. It's always helpful to get opinions and views from others, especially if they are more experienced in the matter, if only to set one's own viewpoint straight. I'm grateful for all you guys replies, but I don't feel like bothering Microchip with this.
Regarding Nordic - besides the circulating copies / clones (like the SI24R1), I guess it's also not helping that they are fabless, unlike Atmel / Microchip, in which case it seems totally reasonable that the various fabs may have slight marking variations. I just didn't expect that from those ATmegas which seem to have been produced in one and the same factory.
But it's certainly a neat touch from Nordic to offer a free test.
Here in DK, we started with closing down all public schools, and educational institutions 2 weeks ago. For my part, I have been working at my home office for the last 2½ weeks.
The government is taking a more and more strict approach to the current situation, limiting the freedom of movement, the latest is that (unless you'r a family living together) you are only allowed to be 2 persons in the same area (taking a walk etc.). And the schools etc. are closed at least until 14th of april (after the Easter holidays in denmark)
Luckily I live in the countryside, so we have lot's of space around us, with forrests etc. So we can get out in the fresh spring air, almost without meeting other people, or if we do meet other people, we can keep a safety distance of 2m. This also means that our local grocery store is not overly crowded with people, when we do shopping, as opposed to the shops in bigger cities.
As a kind of bonus, I get the opportunity to order some gadgets for my home office, now that I work full time here. "But honey, this thing will unclutter my desktop / make it easier for me to switch between work and hobby".."
PS: one downside will probably be not being able to wake up programmatically and double the node as a e.g. temperature / climate sensor, as I had in mind.
Sorry for the confusion above, too little sleep in the last days (at least I hope that explains it )
Perhaps @Yveaux can help here on how to combine pin change interrupts and timer wake into a successful sleep() command? So far it looks like that would be possible with Low-Power lib, but this is not compiling in conjunction with MySensors 2.3.2.
@bjacobse Excellent! You're the first and only person I've ever met who knows anything about this very important topic.
By "hydrofob", I assume you mean hydrophobic coating? If so, just how effective are they at preventing moisture intrusion, and which type or brand of hydrophobic coating is the best?
