    What you’ve suggested will work. Personally I’d be using a serial port on the Pixhawk, not USB. Also, powering a Pi over the GPIO bypasses the polyfuse. There are pads on the bottom of the Pi near the micro USB that you can solder 5V to.
    So: I’d do it differently to be more robust, but your way is easier and will probably be fine.

    before hardware goes, I wonder where I can find the latest Rover framework for simulating? Cause the latest Rover has come to 3.5, however i could only find the 2.5 version
    Anyone knows about this~Thanks in advance

    @DaHaiHuha firmware.ardupilot.org should have all you want and need

    Thanks, yes it's firmware...

    I have been wondered if I could find a way to output a constant 5V and adjust it to lower electric lever like 1v from main out pin or Aux pin in Pixhawk(using rover), already check the docs and find out I can use main out to output PWM or Aux to output an instant high/low level, they will act as a signal for controling other equipments,

    @khancyr are you aware that DJI might release a ROVER today ?
    patrickpoirier51
    @patrickpoirier51
    The DJI rover stuff. Not actually new, just hasn’t been marketed to consumers before

    @patrickpoirier51
    Interesting, they will start to sell parts
    Hopefuly with some "openess" of the underlying protocols ;-)

    Hello all, just curious if anybody knows if the RPLidar A2 can be used for obstacle avoidance with the current version of rover?
    I noticed in the docs that dodge does not work with the 360 degree lidars and I was hoping to be able to use it for obstacle avoidance on a survey type mission.

    Yes, it can with a PR from Tom Pittinger

    If I am having hardware issues with an RFD900x where should I post?
    bj-neilson
    @bj-neilson
    @TunaLobster what sort of issue? I briefly experienced one of those. Was a poor connection on the radio end of the cable from my Cube. Ensure the radio has sufficient power (not from Cube) as a start.

    @OXINARF
    @TunaLobster You should contact the store/manufacturer.

    My issue turned out to be from the Windows serial mouse driver activating when it saw the mavlink data. Kind of odd, but it makes sense. Andras helped me out on the forum.

    PX4 flow sensor is not working in Pixhawk 4's I2C A port. Any idea?

    @patrickpoirier51
    @sujiv0 3 common issues; flash with the correct code, power with dedicated UBEC and use a rangefinder (yes you need it to get the code working)
    sujiv0
    @sujiv0
    @patrickpoirier51 As I mentioned discussion, the same is working in I2C B port (UART& I2CB) with same configuration. And it's not giving data when I'm changing from I2CB to I2CA

    Any help with porting to SPRacingF3 board?
    Stephen Dade
    @stephendade
    @jonmendenhall - the F3 boards do not have enough flash memory to hold the APM firmware. Need at least 1Mb flash

    Hi, I'm confusing about how to power a servo with pixhawk 4.
    I connected the signal to OUT7 and +/- to a BEC and didn't work.
    Then I connected the negative of the servo to the negative bus of pixhawk and smoke appears on the servo :(
    Here is a wiring diagram:

    Hi, I am looking to build custom power distribution board to fit my drone that can handle the 120 A of all ESC. Do you know any good supplier ? Pcbway and jlcpcb only allow 3oz boards and I don't want to have a large board

    Hello, I am switching my hardware to the cube black. I've read on the forum that bulletin about some trouble with some versions of hardware. I wanted to hook it to mission planner and see if it says the warning. So far it hasn't throw it but I am not sure if it is because I've uploaded a firmware built from source. I used BlackCube target on waf, is that correct? I noticed also CubeBlack+. With arduplane built from source mission planner doesn't give any warning. I've tried to upload the firmware directly from mission planner but somehow it doesn't detect the board. Should I be sure that my hardware is not affected by that bulletin? Thank you very much.

    i have a pixhawk1 with a broken off usb connector....I am unable to update ardupilot releases. I have tried hooking up via the USB port pin output (vin, d-, d+, g) and none of my linux or windows PC detect it....i try flashing via serial port using an USB-TTL converter and no luck either....i was wondering if I can flash the latest ardupilot hex via ST-LINK device? but I need to locate the proper pins (SWDIO, SWCLK)...is this possible?
    David Sastre
    @Davidsastresas
    I think in Pixhawk1 those pins are exposed on the PCB. You should be able to upload the firmware directly by them, in the ardupilot firmware download page, I think you need to flash the firmware with bl version if I am not wrong.

    Hello, I'm trying to port Ardupilot code to STM32F779.In list of supported hardware board i could not find this exact board. The nearest board i could find was STM32F777x.
    Can anyone mention the list of steps that i need to follow to port my code to STM32F779?
    Also please mention how to verify whether or not my code has been ported successfully to the said board. Thanks in advance..
    Andrew Tridgell
    @tridge
    @syedhammadhussain I would guess that 777 and 779 are very similar. Quite likely you can treat it as a 777 for initial port

    @Rimokaci
    Hello, I'm trying to use two digital airspeed sensor (ms4525) with i2c splitter and I plug it into Pixhawk4's port i2c. In mission planner I read correctly after the values of airspeed.
    My question is how Pixhawk4 could read it despite they have the same address (0x28H) and connected to the same i2c port(bus)

    @davidbuzz
    @syedhammadhussain - the core file you need to get right to do a 'port' is called hwdef.dat, and there is basically one of those for every port/board... as tridge suggested find something that is as clase as you can to your cpu type, and them adjust it . https://github.com/ArduPilot/ardupilot/tree/master/libraries/AP_HAL_ChibiOS/hwdef
    ... and my guess is that this file based on the 777 is the most relevant point to start from..

    I am looking for cheap/budget logic analyser Wich one would you recommend ?
    Peter Barker
    @peterbarker
    @Silvanosky saleae if you can afford it (check to see if you qualify for their discounts). saleae knockoff if you can't.
    Charles Villard
    @Silvanosky
    @peterbarker thanks that was the brand I saw many people had in ardupilot devs and I did not know that they do discount for students. Has the Logic 8 enough sample rate ? I never used this kind of device but I think it would be very usefull to debug all my protocol programming
    Buzz
    @davidbuzz
    there are very cheap chines clones of saleae around, generlly work fine too.
