Firmware update Anleitung (für PicoAPRS und PicoAPRS-Lite identisch):
Laden Sie den passenden CP210x USB to UART Bridge VCP Treiber von Silabs herunter und installieren diesen (unter Linux meistens nicht erforderlich!)
Laden Sie die korrekte Firmware (oben) herunter und entpacken diese
Unter Windows, führen Sie die Datei START_UPDATE aus dem Ordner "Firmware" aus und befolgen Sie die Anweisungen
Unter Mac öffnen Sie bitte das Terminal, wechseln in das Verzeichnis Firmware -> data und kopieren folgenden Befehl in as Terminal: (wenn Sie eine Fehlermeldung "command not found" erhalten, geben Sie bitte zuerst "chmod 755 avrdude" im Terminal ein) ./avrdude -p atmega1284p -Cavrdude_mac.conf -carduino -P/dev/cu.SLAB_USBtoUART -b 230400 -Uflash:w:firmware.hex:i
Unter Linux geben Sie bitte zwei Befehle nacheinander ein: sudo apt install avrdude (zur Installation von avrdude. Sollte dies bereits installiert sein, kann dieser Punkt übersprungen werden).
wechseln in das Verzeichnis Firmware -> data avrdude -p atmega1284p -carduino -P/dev/ttyUSB0 -b 230400 -Uflash:w:firmware.hex:i
Firmware update instructions (identical for PicoAPRS and PicoAPRS-Lite):
Download CP210x USB to UART Bridge VCP Drivers from Silabs and install (mostly not required on Linux!)

In this mode the PicoAPRS works like an APRS Tracker
There is also a new "AutoPower" function. You can now choose between Auto Power OFF and Auto Powersaver.
These two modes are automatically activated when the USB power is disconnected. This is very helpful in vehicles with power supply via the cigarette lighter socket!

And if this also not known and ONLY if you use a HOUSE as APRS symbol, the previously saved HOME location will send every 30 Minutes. Even without GPS fix.
- Button debounce time is lower, so you can use the buttons faster.
- if display is off while screensaver is on and battery goes empty: Display will enabled to show "low batt" before shut down
- NEW: option to set TX interval to OFF (no beacon will send (also not every 30 minutes!), only for receiving)
