MCP4725 and VL53L0X for analog distance

by ttoth1331 on Wed Jan 23, 2019 8:04 pm

Is it possible to wire a VL53L0X and MCP4725 to get an analog distance output? I'm a beginner trying to build this 3d scanner https://www.youtube.com/watch?v=-qeD2__ ... e=youtu.be and upgrade the sensor to TOF. or is there an easy way to update the code and re-wire this build to accept this sensor? I'm looking to build a larger scale version of this scannerr to get point clouds off automotive transmission sized objects.

Thanks,
Tim

You would need a microcontroller to read the distance from the VL53L0X and write it back out to the MCP4725. Seems more straightforward to just adapt the scanner software to read directly from the VL53L0X.

Ok thanks for the quick response, I wasn't sure if that could be wired inline to convert the signal. May not be the right location for this question but It looks like using the the Arduino Pro Micro I would be out of I/O to accomplish this, could you recommend which controller would best fit the sensor change for this project?

Swapping out the processor would probably involve a substantial re-design of the board. For minimal impact on the design, you could use something like a Trinket M0 to handle the VL53L0X and MCP4725, then feed the analog output of that into the existing circuit.
