Compass QMC5883L doesn't show in ardupilot, but work with betaflight

HeRobrain_3 · July 30, 2023, 9:19pm

Problem:

Compass module QMC5883L isn’t detected in ardupilot.

Information:

First.Gps part of the M10Q-5883 module Matek M10Q-5883 Gps&Compass work fine (use UART4) and the da/cl is wired to sda/scl pad of my H743-HD H743-HD Specs and infos.
Also, I conclude the QMC5883L isn’t defective, because I can use it with an arduino and with betaflight.(GitHub link)
The gps module work with the flight controller and compass work with an arduino/betaflight. So it’s a communication problem.

Question:

How can I see if the I2C work on my flight controller? (just have bunch I2C modules, but none are made for drones)
Is this a params issue?
If the I2C fonction is defective on my board, can I convert I2C to UART?

Thank you for your help.

This sounds like it may be a wiring problem. Or a parameter problem.

Check that your serial port setting (SERIAL_PROTOCOL) parameter setting is fir the serial port that the GPS is actually wired to .

Try flashing 4.4.0-beta3 and see if it’s recognized.

I tried 4.4.0-Beta3 but still nothing :

HeRobrain_3 · July 31, 2023, 4:06am

The I2C and UART wiring is good. The gps work perfectly, but not the compass inside the M10Q-5883 module.

I have two of these and both work fine, so it is a problem with your config.

Try the -bdshot target and see if that works any better

dkemxr · July 31, 2023, 2:53pm

I only see a Bdshot version for the Skystars FC.

HeRobrain_3 · July 31, 2023, 5:39pm

What do you mean by:

?

Is Bdshot a ecs protocol or something else?

HeRobrain_3 · July 31, 2023, 5:46pm

Do you talk about H743-HD and M10Q-5883.
If your talking about this combination, can you link your params file?

HeRobrain_3 · July 31, 2023, 6:30pm

I don’t know if it’s helpful.

M10Q-5883. Try the version here: ArduPilot firmware : /Copter/latest/SkystarsH7HD-bdshot - it’s possible you are running into a DMA conflict I suppose.

geofrancis · July 31, 2023, 9:08pm

run the i2c scanner script to see if its being detected by ardupilot. It should show up on the messages.

github.com

ArduPilot/ardupilot/blob/master/libraries/AP_Scripting/examples/i2c_scan.lua

-- This script scans for devices on the i2c bus
local address = 0
local found = 0

local i2c_bus = i2c:get_device(0,0)
i2c_bus:set_retries(10)

function update() -- this is the loop which periodically runs

  i2c_bus:set_address(address)

  if i2c_bus:read_registers(0) then
      gcs:send_text(0, "Found I2C at " .. tostring(address))
      found = found + 1
  end

  address = address + 1
  if address == 127 then
    address = 0
    gcs:send_text(0, "Found " .. tostring(found) .. " devices")

I’m not able to run script, because I can’t find SCR_ENABLE params. This board has 2MB flash (right? Specs link), so why I can’t run script?

HeRobrain_3 · July 31, 2023, 9:50pm

I guess you are right.
When connect to an arduino or with h743-hd(Betaflight) it run well, but not with ardupilot. I will retry betaflight to see if the module still work.

dkemxr · July 31, 2023, 10:16pm

Use the custom Firmware builder and enable it. It appears to be disabled by default. Or maybe there is good reason for that…
The QMC5883L is enabled so it’s something else.

HeRobrain_3 · July 31, 2023, 11:56pm

which parameter do I need to select to enable scripts?

HeRobrain_3 · July 31, 2023, 11:57pm

dkemxr · July 31, 2023, 11:59pm

The one that says LUA scripting?

Yes. When I click your link, select Latest, the Skystars board and go to Other it’s right there.
