The electronics manufacturer, Microchip, has kindly sent me a sample of their PIC16LF1824T39A-I/ST microcontroller. It’s only 8 bit but sports a fully integrated RF transmitter and guess what ? The frequency of this part is 868MHz (although they do other bands as well). The part is a TSSOP package which means I’ll need to design a PCB to which I hope to add the antenna. When that’s done and all components are placed I can write some code that will hopefully be able to activate the Xyloband we have from the Coldplay Concert (Wembly 2016) – don’t know about them but my head really is full of dreams.
I’ll publish the circuit here (or on my Github account) and any other findings.
