Re: HC - SR04 Python Programming Help

Hi @pcmanbob'
Have you actually used the code and timings which you quoted with success. I ask as I am trying experiment with this sensor on an Arduino Uno project but am having no success.

Using the HC-SR04 ultrasonic receiver

Has anyone used the Sensor mentioned in topic header? If so could they make the code they used to pulse & activate it that was used available to me through this forum, I would be very grateful.

Aiy software not re-booting after shutdown

I have just created a boot CD for the Aiy software and booted up successfully. However when I shut down using the menu 'ShutDown' I cannot get it to boot up again a short time later. Can anyone suggest what may be wrong as this has happened twice from different copies on different CD images..?

When compiling C++ files using the Terminal Window do you add a + sign to gcc vis gcc+. also where should any 'include' libraries be stored within Rpi3.

Re: Pi3 lacks power

Many thanks 'rpdom' for reply. I think you are correct in what you you say about the RPi3 pins not being able to supply enough current. In fact I have given up the experiment with this 7 Seg as being too much for the Rpi3 to drive.
