IR laser ToF VL53L1X , C++, VL53L0X

Got mine from Pololu.

https://www.pololu.com/product/3415

Has anyone tried the newer model, using C++ and is existing VL53L0X code compatible?

Better yet, any updated code to handle the newer features?

Re: C Library for VL53L0X time of flight distance sensor

Hello,

do you know if your library would be compatible with VL53L1X?

thanks

wiringPi (C) mcp23s17 interrupts

Hello, I've enjoyed using the wiringPi C library in various ways. Used it with vanilla GPIO, with interrupts, with MCP3008, MCP23017, and now the MCP23S17. However, I'm a bit stumped on this particular issue: Does the wiringPi library support (and how) using the MCP23S17's interrupts? At the moment,...

Re: Motor Controllers With Raspberry instead of Arduino - lack of software support

correct me if I'm wrong here but I chose RPI over Arduino for the following: -- USB? -- Wifi? -- OS? -- if / when my sdcard craps out from too much read/write during all the development I do.. just replace it.. but with the Arduino ? I think I would rather buy and add some A-to-D for the RPI, than t...

Re: Motor Controllers With Raspberry instead of Arduino - lack of software support

I found some limitations with Python - performance - speed. just didn't cut it. (that and I hate the required code-formatting).

Re: Motor Controllers With Raspberry instead of Arduino - lack of software support

all good points above. Someone at the makers of Roboclaw finally did get back to me regarding porting Arduino C++ over to Raspberry... hopefully this will happen, and I can post it somewhere for others. And maybe generalize a bit more for newbies who really don't want to get into Arduino but are fac...

Motor Controllers With Raspberry instead of Arduino - lack of software support

Is it just me, or is everyone ok with the state of software support of motor controllers? I refer to the more expensive ones , example Sabertooth, or Roboclaw. They both offer Arduino examples, but then there's header files .. I don't have an Arduino, I don't want one, how do I start the porting? I ...

Re: Trouble communicating with RoboClaw motor controller

Hi, could you go over the steps more specifically, if you remember? I am running Raspbian, I notice seem to have both python 2 & 3, I downloaded the python examples for the Roboclaw, the error is no '_port' . The people from Roboclaw just keep saying that i need pyserial and python 2.7. But i though...

python 2.7, pyserial, USB, Roboclaw -- no _port

I really have tried searching through all the forums. confusing. The makers of Roboclaw wrote their test pythons scripts (and Roboclaw class) with Python 2.7. As of now, will NOT work with python v3. So I'm stuck with that restriction. When I run the basic script, it complains that "AttributeError: ...

Re: Pi 3b , undervoltage, usb, 5v regulator

Update on the supposedly bad 5V stepdown regulators from Pololu causing an undervoltage on Pi 3B+. I looked some more . There are 2 ground pins on the regulator. I guess one's for the Vin, and one for Vout. Seems silly, but that got me thinking. I decided to get away from connecting wires and just d...

Re: Pi 3b , undervoltage, usb, 5v regulator

1) regarding the charger.. I was able to get a 3A one from Amazon, for my Pi 3B+. Seems to have worked fine. I also run a fan, plus I've run other things. I just now used a variable power supply with current reading, (well, through a 5V stepdown but regardless) the Pi only drew 170mA doing nothing. ...

Pi 3b , undervoltage, usb, 5v regulator

Hello, I am not sure if this is the correct place to inquire but pehaps you have a suggestion. I bought and installed the Pololu 5V stepdown switching regulator. Power is supplied by two 18650 cells in series, charged. The Raspberry is not directly wired to anything other than being in the same chas...

Re: New Raspberry Pi model 3B+ 1.4 GHz, 330Mbit Ethernet, 802.11ac, PoE

I notice the metal casing surfaces on the cpu (is the other one ..blue tooth? wifi? ) (in the corner between gpio and sdcard) aren't flush with each other.

I had previously bought a dual-fan heatsink for another Pi 3b, but then got the B+, thinking to use the dual-fan.... :(
