Hmmm so is the size of the data chunk the issue here? It took some
looking at the patch with some super arcane int to ascii to float
wizardry to even read the values coming from one sensor.
Could you please elaborate on this? I _THINK_ that the firmware right
now is using the digital connector to
You would just send the data as an analog value, which gives you 14-
bits of resolution. In the Arduino firmware, it would just take the
values from the sensor and report them as a analog value using the
Firmata protocol. The [arduino] object already understands the
Firmata protocol, so
This firmware reads 2 ultrasound sensors at the same time, I guess it
might read more with a little adjustment in firmware. Firmata
Ultrasound firmware will be really great, I remember we had this
discussion earlier, and there was some sort of problem to code Pulse
in Pd_firmware.pde so
Yes, it seems better to code these microsecond pulses in the firmware
rather than letting Pd control this directly. Maybe at audio signal
rate this would be more satisfactory, I am not well-versed in this.
Our plan is to use 6 sensors, so we will attempt to modify the
existing ultrasound firmware
Thanks so much Koray, it works great!
I see you used the same Arduino code for the sensor as I had found,
and your Pd patch is very well-written and well-commented.
I appreciate this, because I did not want to try coding
microsecond-level events in Pd by porting the Arduino code and using
Hello Kyle,
I am glad that those patches worked and helped you out with your
project. I guess big thanks goes to Hans for them, cos during that
time, I just modified his existing multi-sensor patches and developed
them further to use in my project.
Koray.
Does this firmware handle multiple ultrasound sensors? If so, it
would awesome to make a Firmata Ultrasound firmware. I just started
making the Firmata protocol into a library so that people can write
more firmwares and still use the same objects in the host software.
A multiple
Well, we are going to be using multiple sensors, so I will let you
know if this code works with them, once we get to that phase of the
installation.

I think the ultrasonic sensors send serial bytevalues and not an analog
value, correct? how can you connect them to the pduino? or how can you
connect even more of them. can firmata handle serial inputs?

Hi Koray~
I am working on a group project that involves Arduino and the parallax
PING ultrasonic sensors. Would you be willing to share your Pd patches
regarding this usage, as indicated in this email?
Thanks in advance!
