Hardware-Fallstricke
FM-Antenne
- vorhanden am Auto etc
- hat möglicherweise eingebauten Verstärker
- Verstärker schwierig zu finden (ist meist außerhalb des Autos)
- Phantomspeisung zur Stromversorgung irgendwo drin?
- Buchse? ISO oder DIN? Wahrscheinlich DIN.
- Impedanz? 150 Ω (wahrscheinlich)? 50 Ω (wahrscheinlich nicht)? Antennenanpassung nötig?
EMI
- ElectroMagnetic Interference
- unsere Hardware stellt viele Hochfrequenzstörquellen dar
- Störung von außen gibt’s vielleicht auch
- Audioverstärker sollte nicht gestört werden
- Faradayscher Käfig nötig (1 oder mehr)
- Filterplatte mit Masse
- min. 2 Lagen
Ghost in the Machine
- Pull-Up-Widerstände sind auf den Kommunikationsleitungen notwendig, damit kein Blödsinn gesendet/empfangen wird, wenn ein Gerät ohne Strom ist
Software
- Selbstgebastelte (wenn sinnvoll User-Space-) Treiber für die Hardware
- MT3329 geht über gpsd schon
- xgps-Testprogramm
Mainline Linux
- Hardware und Verbindungen müssen im Device-Tree-File eingetragen sein (d.h. eingetragen werden)
- Device Tree
- offiziell sollten für Peripherie Device-Tree-Overlays verwendet werden (wird zusätzlich zum Board-Device-Tree-File geladen):
- Spezialsyntax __overlay__ { … }
- dtc -@ xxx.dts
- Linux Command Line: dtoverlay=xxx.dtb beim Booten
- geht nicht in Debian, weil "/plugin/" unbekannt
- Hack: Board-File editieren
- bei unserem Host: sun7i-a20-olinuxino-lime2.dts
- folgendes hinten anhängen und dann: make dtbs und die entstehende Datei sun7i-a20-olinuxino-lime2.dtb dem Bootvorgang zur Verfügung stellen
- offiziell sollten für Peripherie Device-Tree-Overlays verwendet werden (wird zusätzlich zum Board-Device-Tree-File geladen):

- Für spidev in Linux drivers/spi/spidev.c editieren:
- das Array spidev_dt_ids erweitern um
{ .compatible = “atmel,tss463aa” },
- vor dem (existierenden) Sentinel
{},
- dann ausführen:
make modules make modules_install
User-Space
- Zugriff auf SPI über spidev (Später: Selbstgeschriebenes CAN-Kernel-Modul)
- Linux-Source muss editiert werden., damit /dev/-Datei erscheint
- es existieren verschiedene Headerfiles für SPI. Vorsicht! linux-headers-Paket im User Space installieren&verwenden, nicht /usr/src/linux/include
- Zugriff auf I2C funktioniert auch so
- Zugriff auf UART funktioniert auch so
- Interrupts (EINTxx):
- /sys/class/gpioXXX/edge
- /sys/class/gpioXXX/uevent
- poll() oder select() auf errors
