1. Schnittstelle des FlySpy zur Jeti - Telemetrie

1.1. HW Schnittstelle Raspberry Pi zum Arduino ( Version 1)

Im ersten Versuch wird eine parallele Schnittstelle des GPIO-Moduls des Raspberry PI zum Arduino realisiert

Steckerbelegung:

Raspberry Pi Flachbandkabel Arduino
Buchse Stecker
1 Bit1Pin = 6; //Digital
2 Bit2Pin = 7; //Digital
3 Bit4Pin = 8; //Digital
4 Bit8Pin = 9; //Digital
5 Bit16Pin = 10; //Digital
6 Bit32Pin = 11; //Digital
7 Plus 5 V vom Pi

1.2. zweiter Versuch Adapter-Platine ohne verlötete Pull-Up-Wiederstände (per SW realisiert) (Version 2)

In der neuen Variante werden sowohl auf der Raspberry Pi Zero-Seite als auch auf dem Mini-Arduino die Pull-Up-Widerstände per Software gesetzt. Die Adapterplatine sieht dann wie folgt aus: upload:Adapterplatine%20V2b.png

GPIO01 1er Bit1Pin = 9
GPIO04 2er Bit2Pin = 7
GPIO05 4er Bit4Pin = 6
GPIO06 8er Bit8Pin = 4

1.3. aktuelle Version ohne Adapter-Platine und ohne verlötete Pull-Up-Wiederstände (per SW realisiert) (Version 3)

In der neuen Variante werden sowohl auf der Raspberry Pi Zero-Seite als auch auf dem Mini-Arduino die Pull-Up-Widerstände per Software gesetzt. Die Adapterplatine entfällt da der Arduino und das GPS direkt auf den Raspberry aufgesetzt werden
