As some of the forum members know, I have been spending a little of my spare time attempting to create an FM radio hat for my Pokitto. Today, I finished it! (or rather, got it to a state that I am happy to share with the world).
Features -
Customer background image (/_fmradio/background.bmp)
Auto search Up/Down
Volume Up/Down
Record to SD card
Up to 10 preset stations can be saved
A readily available RDA5807M chip was used, which communicates with the Pokitto over I2C protocol using a software library. The audio output from the chip is captured through an analog pin on the PEX header and processed through the Pokittos own sound hardware, which enables us to record the audio to the SD card as well as using the Pokittos to control volume and potentially performing some EQ processes.
Radios arrived from Ali now I need to order a PCs lol. Or just freeform it . How hard is it to do the Chinese pub ordering thing?
And will
I mess it up like I somehow did the bike computer?
This is really cool. Personally I don’t really use radio, but it would be really cool to maybe see this in the official hat shop. Maybe @jonne can cook something up.
Just grab the kicad zip file from the first post and head over to PCBway, it’s straight forward. They even give a discount on your first order,so you can probably keep the price down to shipping only
