 INAV MApping

ArduPilot Mapping

• *  If connecting just one GPS to UART4(TX4/RX4),  pls set SERIAL3_PROTOCOL -1 or non “5”.   otherwise ArduPilot will stop searching for GPS during bootup if not found on the first port configured for GPS protocol. 

Frsky Smartport Telemetry

• non-inverted (hacked) S.Port signal

• any spare Uart_TX
• SERIALx_BAUD   57
• SERIALx_OPTIONS  7
• SERIALx_PROTOCOL  4  or 10(for yaapu)

DJI FPV OSD (ArduPilot 4.1)

https://ardupilot.org/plane/docs/common-msp-osd-overview.html

• OSD_TYPE = 3
• SERIALx_PROTOCOL = 33
• MSP_OPTIONS = 0 (polling mode)

Notes & Tips

• F405-WSE has INAV firmware preloaded for QC

• INAV2.5.x  downloaded from configurator doesn’t support new barometer DPS310.   Pls use INAV firmware 2.6.x & new configurator.
• ArduPilot Firmware “MATEKF405-WING″ supported the onboard barometer DPS310 since Plane-4.0.6 & Copter-4.0.4
• If connecting just one GPS to UART4(TX4/RX4),  pls set SERIAL3_PROTOCOL  -1 or non “5”.   otherwise ArduPilot will stop searching for GPS during bootup if not found on the first port(Serial3) configured for GPS protocol.
