Pi 3 with Radio Transmitter
« on: September 22, 2018, 08:15:55 am »
Wanting to use a FS1000A radio transmitter with a pi3 b+ running latest raspbian.

Lazarus/FPC installed and working.

Ive only really been able in the past to turn on and off LED's using the Pi and Lazarus.

I can get this to work with python examples, but i'd rather use Lazarus/FPC if i can , but can't find anything searching the google box.

I have to research it a bit but aside: did you know you can use the pi3 out of the box as an FM radio transmitter with just a small 20 cm antenna on gpio 4?

Works like a charm and the code can be easily translated to FreePascal.
inline variables like in D10.3 are a bit like Brexit: if you are given the wrong information it sounds like a good idea. Every kid loves candy, but it makes you fat and your teeth will disappear.

The FS1000A is a 433mhz Wireless Transmitter and receiver set. Useful for the many devices using this, like weather station outdoor sensors, remote controllable power switches and much more.
These devices do not listen to the latest hits on the radio  :D

If it is directed at me: I know all that. I wrote an aside....
