Thank you for writing this library. It works great.

However I still have the following problem. Since I access the TF-Luna via my own library in a separate file, the library has no access to the Serial device. For a larger project it can be that the Serial device remains out of scope. So if things do not go as planned, I can't do a tfli2c.Print_Status. (See project: House2 TF-Luna HAL )

Feature request:
Provide a function to get the value of tfStatus. And/Or provide a function to copy the message to a char[20] buffer.

The two example are not showing in the menu example because each example have to be in separated folder named by the ino file
Users\UserName\Documents\Arduino\libraries\TFLI2C\example\TFLI2C_simple\TFLI2C_simple.ino
instead
Users\UserName\Documents\Arduino\libraries\TFLI2C\example\TFLI2C_simple.ino

Thanks for your work on this lib.

Set_Enable and Set_Disable functions's definitions should be swapped.
When I wanted to turn off TF-Luna's light I had to use Set_Enable function instead of Set_Disable function. Same goes for the case when I wanted to turn it back on ( I had to use Set_Disable function instead of Set_Enable).

Hi, thank you for providing this nice library.
I have some problems connecting the device correctly to my Arduino UNO (R3).
Serial output is always like:

Status: I2C-WRITEStatus: I2C-WRITEStatus: I2C-WRITEStatus: I2C-WRITEStatus: I2C-WRITE

I connected Luna to UNO like:

• 1 -> 5V
• 2 -> GPIO18/SDA
• 3 -> GPIO19/SCL
• 4 -> GND
• 5 -> GND
• 6 -> UNCONNECTED

Can you give little support how to connect please.

Many thanks in advance.

Hello—I'm using the example code "TFLI2C_simple.ino"; Arduino UNO; and a Benewake TF-Luna.

My issue is this: the only output is the setup print:

TFLI2C example code simplified
4 NOV 2021

No values coming out of the sensor. My question is this—I've got no red LED lit up on the TF-Luna; does this indicate that the sensor is broken? I'd obviously like to know whether I can skip more troubleshooting with the code and should instead just order another LIDAR sensor!

Much obliged—and thanks for providing all these helpful scripts and guides!

Hi Bud,

Thank you for your wonderful libraries! I was previously using the TFMPlus library with my TF Luna and it was working great, however I am now switching to I2C and using the tca9548A mux such that I can gather data from 4 Lunas on one board (Arduino Mega or Nano).

In the TFMPlus library, I was able to set the settings to MM and noticed there was no function for MM in the TFLuna-I2C library. Did I not look carefully enough in the .cpp / README files?

If there is no function, could you help guide me on how to switch the settings to MM? I see on the data sheet from Benewake that you can change output format using different hex inputs, but I'm not the strongest with this type of coding. Thanks in advance for any help!

Cheers,
Alec

hello!

thanks for the awesome libraries for tfmini products :)

will you be releasing the uart version for tfluna as well?

thanks!
