Re: PoE hat needs stackable headers

The problem then comes form the people not wanting to stack anything on the header, I would guess their target market asking for PoE in a HAT over to bother adding the pins and capable Ethernet just don't need them. They can't please everyone. Just skimmed that second MakerSpace link, (*) but on the...

Re: PIGPIO Callback

Usually Joan answers these questions at some point. (The author of pigpio). But plenty of other can answer them. But if it works from simulated square pulses, then it probably works. To me that would then be the hardware, how square are the pulses... Are they all meeting the threshold voltage for a ...

Re: wiringpi vs pigpio vs bcm2835 lib

pigpio/pigpiod will be quick to code with as there are plenty of example (efficient) and I believe it should be quick to type it up (speed). ;-) There are benchmarks for gpio readings, do a search but I'm not sure which pi they are on WiringPi is transferable to Arduino and other paltform iirc so ef...

Re: PIGPIO Callback

Just a quick one as others are better at this than me.
Have you checked the pulses you are actually getting? (Oscilloscope or similar?)

Have you checked the pulses the Pi is seeing at the pin? With piscope http://abyz.me.uk/rpi/pigpio/piscope.html

Re: RPI3 - WiFi stops working after rpi-update

what are you using that rpi-update gives you ?
but if you must
then after the
sudo apt full-upgrade
and if it works there take and backup image

or wait till the Techs spot this and know what may have gone wrong.
Maybe read github for reports on problems with the testing you are doing.

None of that original tutorial touches the Bluetooth part. You enable and start the service ttyAMA0 is Bluetooth. You could just use /dev/ttyS0 if no serial0 is there.
