That document has many inaccuracies, including all the checksums for the example commands being wrong. I ended up extracting the correct information from the DFRobot_LIDAR07 library on github. The fw. on my sensor was 2.17, so maybe the communication protocol changed in the meantime. That might explain why the Host software was not working (but the arduino library did work correctly)
We tested with a FireBeetle ESP32, a board that has pull-up resistors on-board on the I2C bus.
We suggest you take a look at the schematic for the XIAO ESP32-C3, all I2C pull-up resistors for this type of ESP32 board should be on board.
JaneYu Can this be used with a bi-directional IIC logic translator (level shifter) to be made compatible with micro:bit type microcontrollers? Specifically, interested in compatibility with the Arduino nano 33 BLE sense rev2 with ARM-type processor running at 3.3 V levels.
Thank you in advance for any help.
JaneYu We tested it with ESP32 and it was able to be used properly. (The ESP32 is also a 3.3V microcontroller.)
But we tested it with MicroBit and it didn't pass, our guess is that the I2C level signal of MicroBit is different from ESP32.
I have bought 4 LIDAR07 sensors and want to connect to an arduino nano every through I2C. I cannot find whare can I define the I2C communication address for each of the 4 sensors
thank you
JaneYu I'm afraid this sensor could not change the I2C address.
The I2C address is 0x70
JaneYu Is this sensor capable of sensing through glass (after calibration maybe?)
JaneYu Sorry it can't, maybe you could use this one:https://www.dfrobot.com/pro...
