Hi,
I'm after some advice:
For an installation piece I'd like to do I'm investigating range finder sensors (for outdoors).
Has anyone experience of the Maxbotic URF's and any tips they'd like to share for getting the data into Pd?
Cheers,
Julian

I connect them to the analog inputs of an Arduino and send the data to Pd which reads it using [comport].

Hi Martin,
Is this with Maxbotic and if so which one? I'm going to be running the sensor with an RPi as standalone so presume it's a similar setup (I believe comport runs fine on RPi)
Would you mind letting me have a look at a patch for translating the input data (if you use/need one). I know from utilising xbees that the input data was tricky to parse - to me anyway.
Cheers,
Julian

I use the MB1010 (MaxSonarEZ1). The analog output is very low level and also quite noisy, so a RC filter would be a good idea. The serial output is RS232 on 0-5V, so you need to invert it before reading it with a microcontroller USART input. The format is ASCII but it should be readable in Pd: from the output of [comport] you need to make lists of 4 characters starting with 'R' and convert the last three digits to a single float. That actually looks more reliable than the analog but I haven't tried it. I attached a patch to do that.
With the Pi you probably need to watch out for voltages above 3.3V on the IO pins.

Hi Julian,
As for the URF, I can't give you any infos but I've been using Maxbotix's indoor sensors a few times.
One thing you really want to take into acount is the fact that sensors interract with each others, you therefore need to chain them properly. You might want to take a look at power filters too. Maxbotix's tutorial page has been quite useful to me so far.
As to get the infos to pd, I've been using these sensors with a raspberry pi. My option has been to collect the data from the RPi's GPIO using python and then send them to pd using OSC. I'm starting to write small tutorials explaining what I've been through, if you use the RPi too I'd be happy to point them to you.
Have fun, Alex

Hi Alex,
Many thanks for the info.
What are 'power filters'?
Yes on RPi, so tutorials would be very helpful.
Best wishes,
Julian

'Power filters' are simple RC filters you can solder directly on the sensor, they help eliminating electric noise. Since the analog output of the sensor depends on the voltage with which it is fed, the cleaner the supply voltage, the better the analog output. I don't know which sensor you're gonna us, but assuming it works like the MB1000 or MB1200, you will find a lot of useful tips inside the datasheet and in the tutorial page.
I'll start cleaning up my mess and a few short tutorials should be on my github by this evening.
Best, Alex

Hi Julian,
The WRM1 seems to work the same way as the ones I know. I'd be interested to know how it reacts and what you do with it!
My git hub is alx-s. I've just added athe RPi_tutorials repo (https://github.com/alx-s/RPi_tutorials) with a first tutorial concerning OSC bewtween python and pd. Keep in mind I'm new to git and I write the tutorials as I work. If you spot any mistake, have, suggestion or have anything to add, ..., please tell me! That's all I've written for today but others will come by the end of the week (GPIO, using Maxbotix...). Good luck with it ;)
Have fun, Alex
