NAZE32gpsOSD接電線路圖（英文）

1、Setting up Naze32 with GPS and OSD Im in the process of building a tricopter for long distance exploration and decided to go with the HYPERLINK /flight-controllers/naze32.html o Naze32 t _blank Naze32 flight controller paired with GPS and the RCTimer HYPERLINK /fpv/fpv-osd/mavlink-osd-minimosd.html

2、t _blank MAVLink OSD (which is just a hardware variant of minimOSD). Ive got everything up and running now and its an awesome combo, but to do so I had to dig through a mountain of forum posts and videos to understand how to set everything up. Im writing this post to compile some of my ah ha! moment

3、s to hopefully help you out with your setup!Before I start, there are a couple of videos by Mochaboy RC that were incredibly useful in this process and they are HYPERLINK /watch?v=rj6IXA2hDW0 t _blank How to setup a Naze32 Acro / Funfly Flight Controller and HYPERLINK /watch?v=ikKH_6SQ-Tk t _blank H

4、ow to Setup KV OSD MinimOSD Naze32, without these I would not have been able to get anything working!GPS Connections and SetupIm using an MTK GPS, but I think this is the same process for other GPS modules like the HYPERLINK /accessories/accessories-gps-bluetooth/ublox-cn-06-gps-module.html t _blank

5、 uBlox. Connecting the GPS is really easy connect the GPSs RX line to the Naze pin labeled 3 and the GPSs TX line to pin 4 (bottom side of the Naze), and then power the GPS however you can (Ive hooked mine up to an unused motor port).Once youve got it connected youll have to enable GPS in Baseflight

6、 Configurator. You may also have to set the GPS type and baudrate.Go to the CLI tab in Baseflight ConfiguratorType feature gps to enable the GPS featureType set gps_type=0 (Check HYPERLINK /multiwii/baseflight/wiki/CLI-Variables t _blank this table for your gps_type)You may also need to change gps_b

7、audrate but check that same table and your GPS specsType save and then leave the CLI tabIf you now disconnect and reconnect you should see the GPS indicator in the top right of Configurator turn green (note: USB will not power the GPS if you have it wired like I do, so youll have to have your flight

8、 battery powering the system!) This should be enough, now just watch the GPS tab for a position fix. This also unlocks a couple of new options on the Auxiliary Configuration page, GPS hold and GPS home!If you dont get a fix after being in a clear view of the sky for ten minutes or so then you can tr

9、y checking the GPS output to see if its really communicating correctly. To do this go back to the CLI tab and type gpspassthrough, this will dump all the data coming from the GPS straight to the console window (note: You cant turn this off once you start it, you have to remove power from the Naze to

10、 get back to normal operation.)If its working you should see the NMEA sentences quickly scrolling through the console. They look something like this:$GPGSV,3,3,11,22,42,067,42,24,14,311,43,27,05,244,00,*4D$GPGLL,3751.65,S,14507.36,E*77$GPGSA,A,3,16,18,22,24,3.6,2.1,2.2*3CIf the output doesnt look so

11、mething like that then theres a problem and you may need to configure gps_baudrate or gps_type differently. If you are getting the NMEA sentences but its not getting a position fix you might be able to get some insight by pasting the sentences into this HYPERLINK /Home/NmeaDecoder t _blank NMEA pars

12、er tool I found.OSD Connections and SetupFor this youll need an FTDI adapter to flash the Team KV OSD firmware onto the OSD board. I have the HYPERLINK http:/store.arduino.cc/index.php?main_page=product_info&cPath=11&products_id=143 t _blank Arduino usb2serial adapter which seems to work well but th

13、ere are many others to choose from. This section assumes youre familiar with the Arduino IDE, which youll be using to flash the OSD board. Heres how to flash the board:Attach the FTDI connector to the OSD and plug it into your machineGo to the HYPERLINK /p/rush-osd-development/downloads/list t _blan

14、k Team KV OSD downloads pageDownload EEPROM_Clear.zip and KV_Team_2.2.zip (or newer)Open Arduino IDE, make sure board is set to Arduino Pro or Pro Mini (5V, 16 MHZ) w/ ATmega 328 and select the correct serial port for you FTDI adapter.Open EEPROM_Clear.ino and upload it (this will clear out any stra

15、y settings so you can start fresh)Open KV_Team_OSD.ino and upload it (shouldnt need to change any config settings)Now you can use the GUI application to set up your OSD board. This application is located in the KV_Team_OSD_GUI folder that came with the firmware download. You can set up various thing

16、s with this app, but first you have to load the correct font onto the board. Ill detail that first but take special note here the font upload will not work unless you power the 12 volt side of the OSD board! So make sure you hook up 12V power to the video side of the circuit before proceeding (see w

17、iring below). If you dont do this the display will be all garbled and not make any sense!Heres how to upload the font:Attach the OSD to computer via FTDIOpen the GUI applicationClick on your devices COM port on the left side (things will turn green if this works)Under Font Tools on the right click B

18、rowseYou should see MW_OSD_Team.mcm listed, open that fileClick Upload (this will take a minute)Okay, fonts done, so now you can check out all the other options like setting NTSC/PAL, metric/imperial units, etc. To save changes you need to click WRITE under OSD Controls in the bottom left corner.Now

19、 you should be ready to wire your OSD up to your aircraft. The video side is pretty straight forward. On the other side just make sure to power it with 5v and connect the RX line to the pin labeled tx in the middle of the Naze board, and likewise for the TX-rx line.At this point you should be able to see your HUD overlaid on your video feed! You dont have to enable an
