Benwake TFmini Plus I2C on CubeBlack

[lumono]

try to install 2 Benewake TFmini Plus I2C on CubeBlack.
follow the instruction document set up TFmini Plus UART to I2C.
then mount on CubeBlack I2C 2 port, there is not any sornaanrrange response.

1. test it by Benewake wincc_tf.exe tools, it works by UART.
2. updated to lastes firmware of TFmini Plus
3. all setting correct on MP.
   not sure where is wrong.
   Thank you for any advice.

Have you looked at my blog ?

Avoidance experiments with the new POC and Benewake TFmini-S

[image] A few month ago, I wrote about setting up an avoidance system using affordable 12 Meter Indoor and 6 Meter Outdoor Time of Flight (ToF) rangefinder made by Benewake : the TFMINI. At the time, there was only the serial version available, and in order to add functionality , I used an Arduino to make it talk I2C. Based on this configuration, I decided to push the concept and constructed an avoidance system using up to 10 of these sensors, …

Thanks @ppoirier,

How do you connect arduino to Pixhawk 2? or just use Arduino to make sure I2C works.
Actually I use Nano ATmega328P Board to connect PC
for 2 TFmini Plus to setup it back to UART mode.

I see you use following command

5A 05 0B 11 7B
5A 05 0A 01 6A
5A 04 11 6F

Once using 5A 05 0A 01 6A changed mode to I2C, the TFmini can’t accept save command 5A 04 11 6F, I think

[ppoirier]

With the TFMini-S the mode change once you issue the save command = 5A 04 11 6F

I use Benewake GUI, send any commend to TFmini plus, there is not response.
Do you get response on the Benewake GUI.

It works now. Just changed address then change mode by the GUI.
The sonar range does not show distance, but confirmed it works in CTL+F proximity.

Hi,
I have changed the address of tf mini s lidar to 23 using Arduino Nano. The lidar works fine when connected directly to the Pixhawk black cube. But when i connect the lidar to the I2C Splitter module, the lidar is not detected. I changed SDA and SCL wires, but still I am not able to find the lidar detection in the Proximity Window. Any suggestions please

[ppoirier]

Are there other devices on the splitter?

Initially I tried connecting tf mini s. But in the long way I need to connect TF Luna too. As a first step I just connected tf mini s to splitter.

I have TF mini plus i2c, it worked for 1 year, but recently it does not work. one is back to UART.
I tried to use TTL to USB test it, it works,
Then I change it to I2C again, it still does not work on cube black.

1. How to test this I2C device works
   tried I2C_scanner by Arduino nano, it does not work.
2. How to convert it back to UART

any advise , very appreciated

My issue is fixed already. Thanks Benewake tech support.
