Re: FM pin on Pi 3

Even if the frequency you target is "unused" in your area, the signal generated by abusing the Pi is so awful that it will clobber a lot of other frequencies, and potentially quite broad bands each time, not just a single channel (the channel width for a broadcast signal is wider than for comms cha...

There are no unused FM bands; the spectrum is packed tight.
I meant one of the regular radio frequencies from 87.5 to 108.0 MHz - one where there is no station broadcasting on it (for a particular area).

Re: FM pin on Pi 3

I saw a spectrum analyser plot of the Pi transmitting on 30MHz and there were equal-sized outputs every 10MHz up to the limit of the measuring equipment at 120MHz. That includes air-traffic frequencies. They probably continued on up and hit the emergency services above 146MHz. How come I'm just now...

Re: FM pin on Pi 3

:( Thanks for the warning, though. I didn't realize that the signal was messy enough to be illegal. Kind of a shame, but I guess you could buy one of those cheap low-powered car FM transmitters ( like this ) - I've seen them as low as $5 here in the US - and hook it to the audio out jack for legal P...

Re: FM pin on Pi 3

Screw the BCM43438 - just stick an antenna on a GPIO :P (edit) DO NOT DO THIS. (/edit) FM transmitting has been done before by using a GPIO on the Pi.[Mod link removed] I'll quote from that wiki page: Below is some code that was hacked together over a few hours at the Code Club pihack.

Re: Connecting Pi and iOS via Bluetooth

What are you using the Bluetooth connection for? Data? Audio? SSH tunneling?

It would help if we had more details about what you are actually trying to do.

Re: Tontec 2.4-inch TFT LCD

For the 2.4" you more than likely want to use: https://github.com/yaolet/mztx06a As there were a lot of fixes which helps to clean up the CPU consumption. The Github version doesn't work for the 2.4 inch touchscreen. The GPIO pin numbers apparently changed for some reason, and it didn't work for me...

I went to the Amazon link, and it looks like the seller used the same page, but actually has a different display board (2.8" instead of 2.4", and doesn't have all the extra I/O and power connector, according to the photo).
