VOXL2 J19 QUP3

Eric Katzfey

@voxltester I would try qshell lightware_laser_i2c start -b 4

@Eric-Katzfey
Eric, this is not working...

Please refer to the driver for i2c....
https://github.com/modalai/px4-firmware/blob/main/src/drivers/distance_sensor/lightware_laser_i2c/lightware_laser_i2c.cpp

Default i2c address is defined 0x66 (102) in this code.
I am wondering what is the i2c address of the VOXL2 J19 - QUP3 port.

I am not familiar with the above cpp driver code... could you please have a look the code and teach me how to enable the i2c connection for the lightware rangefinder?

Thank you in advance....

Eric Katzfey

@voxltester We have never used the device that you are connecting so I am only offering suggestions to help out. When speaking of i2c addresses it is related to the device being attached to the bus, not the bus itself. You can attach multiple i2c devices to the same i2c bus if they have different addresses. But, there are multiple i2c buses to choose from. So, address 0x66 (which is default for that device and doesn't need to be specified on the command line) is for the device and port 4 specifies which i2c bus it is connected to. Also, please look at this file: https://github.com/modalai/px4-firmware/blob/main/src/drivers/distance_sensor/lightware_laser_i2c/parameters.c. There are 2 parameters that need to be set properly for the driver to work. If the default values are not correct then you will need to set them accordingly. For SENS_EN_SF1XX it should be set to 6 for LW20/c.

voxltester

@Eric-Katzfey
Understood. I just figured out address and bus. I am sorry for disturbing you for the basic concept.

Now, I am trying to run it with SENS_EN_SF1XX=6, the command in px4-start is just qshell lightware_laser_i2c start.

By the way, I am wondering where the bus info is described in the driver cpp file. Should I change the code? Because lightware_laser_i2c accepts only R as an option..

Eric Katzfey

@voxltester It's all done in the base class. See: https://github.com/modalai/px4-firmware/blob/main/platforms/common/i2c_spi_buses.cpp

voxltester

@Eric-Katzfey
the versions of px4 are different...
I am git clone from https://gitlab.com/voxl-public/voxl-sdk/services/voxl-px4
in which there is only one parameter in https://github.com/modalai/px4-firmware/tree/0a47ec5d8650f4e97f1eb929405df5dcdb91989f/src/drivers/distance_sensor/lightware_laser_i2c

Anyway, qshell lightware_laser_i2c start is not working with I2C port on VOXL2 J19 - QUP3

Eric Katzfey

@voxltester Why are you not adding -b 4?

@Eric-Katzfey
Sorry for the slow response.
qshell lightware_laser_i2c start -b 4?
No. Not working.

Please see
https://github.com/modalai/px4-firmware/blob/f18864f2e6460e4d2d3d1572d09ee09028c63789/src/drivers/distance_sensor/lightware_laser_i2c/lightware_laser_i2c.cpp
I do not think the -b option is not implemented in the driver source code.

Can you confirming that -b 4 is for I2C port on VOXL2 J19 - QUP3? (https://docs.modalai.com/voxl2-connectors/#j19---external-sensors-2x-uart-2x-i2c)
I am trying to modify the driver code to have the bus information.

Eric Katzfey

@voxltester I tried to explain this in one of my previous responses. Let me add more detail. lightware_laser_i2c.cpp is C++ code. The class LightwareLaser has a couple of base classes. One of them is I2CSPIDriver, so it "inherits" the functionality of that class. That class is implemented in i2c_spi_buses.cpp. It uses BusCLIArguments to parse the command line options. That's where the -b option is dealt with.

Eric Katzfey

@voxltester Yes, bus 4 corresponds to pins 7 and 8 on J19. I would put an oscilloscope on the data pin and see if you detect any activity when you start the driver to verify.

Eric Katzfey

@voxltester And, in general, for all software engineers out there here is a helpful tip. ModalAI is not affiliated with Anthropic in any way but I do want to highlight their Claude Code tool. It can really help you not just write code, but to understand code that is already there. So, for example, in this post there is a question about how the -b option is parsed. It's a bit complicated how all of the pieces fit together but if you were to ask Claude this question: "I'm using the device driver in the file lightware_laser_i2c.cpp. I was told that the LightwareLaser class can take the command line option -b to specify the i2c bus number using the start command. Can you show me where in the code the -b option is parsed?". Claude will then give you this answer:

The -b option is not parsed directly in this file. Looking at the code:

  At line 450, the custom option parsing only handles -R for rotation:
  while ((ch = cli.getOpt(argc, argv, "R:")) != EOF) {
      switch (ch) {
      case 'R':
          cli.rotation = (Rotation)atoi(cli.optArg());
          break;
      }
  }

  The -b option (for I2C bus number) is handled automatically by the BusCLIArguments class, which is instantiated at line 445:
  BusCLIArguments cli{true, false};

  This class is included from <px4_platform_common/i2c_spi_buses.h> (line 47). The cli.getOpt() method internally processes standard I2C/SPI options like -b (bus), -a (address), etc., before returning custom options like -R to this driver's switch statement.

  If you want to see where -b is actually parsed, you'd need to look at the BusCLIArguments class implementation in the PX4 platform common library:

  src/lib/drivers/device/posix/i2c_spi_buses.cpp
  or
  platforms/common/i2c_spi_buses.cpp

  The PRINT_MODULE_USAGE_PARAMS_I2C_SPI_DRIVER(true, false) call at line 435 documents that this driver accepts I2C options (including -b), but the actual parsing is abstracted away in the shared bus infrastructure.

@Eric-Katzfey
Thank you for the info...

I figured out the connection cannot be detected on the port at all..

 $ i2cdetect -y -r 4

WARN  [SPI_I2C] mavlink_shell: no instance started (no device on bus?)
Command 'lightware_laser_i2c' failed, returned -1.

Eric Katzfey

@voxltester i2cdetect is looking for i2c ports on the apps processor so it isn't useful for this where we are trying to use DSP i2c ports. It shows an error message. Can you add the -X option to see if that resolves that error condition?

voxltester

@Eric-Katzfey
Isn't this I2C (J19 7&8) APP I2C or DPS I2C?

7  I2C3 SDA 3P3V   slpi_proc, SSC_QUP3
8  I2C3 SCL 3P3V   slpi_proc, SSC_QUP3

Is it possible to access DPS I2C from PX4?

Please see the outputs of the -X and -I options.

@voxltester slpi_proc = SLPI = SSC = DSP. I think the only option at this point is to attach an oscilloscope and verify the signals.

Eric Katzfey

@voxltester In order to execute on the DSP side you have to have qshell before the command. When you have it you get the error that command is not found. That's probably because the driver has not been built into the DSP image. It only seems to be on the apps side.

@Eric-Katzfey
Never mind. I finally received the DISTANCE_SENSOR data!
I added
CONFIG_DRIVERS_DISTANCE_SENSOR_LIGHTWARE_LASER_I2C=y
to px4-firmware/board/modalai/voxl2-slpi/dafault.px4board.

Thank you for your help.
