I'm thinking my future planned projects will require both digital and
analog signals to talk to the Beagle bone, I heard that the Beaglebone
support 1.8v analog to digital conversions but most of my hardware is
in 3.3v or 5v so my idea is use the Arduino to as a Analog to digital
converter as well as a Voltage converter too...
So back to what I was asking, Is this possible to send data to the
beagle-bone from the arduino and if so can i get some example codes
and/or a link of a document that has personally helped you with this
kind of setup. (Please no 2 second google searches and then copying
and pasting links, thanks)
Yes, it is possible to send data between arduino and beagle. at least 2 common busses come to mind (i2c & spi) and TI makes some really nice chips for connecting together 2 i2c buses with different levels on each bus. There’s also generic serial ports on each, and with a bit more work you could probably get a parallel port out of each. With a shield you could network the 2 over ethernet. come to think of it the bone has a usb host port so you could just hook the 2 together over usb. yea, a lot of interface possabilities exist between the 2 platforms. That said, not really sure you need the arduino to just simply do ADC and voltage. much of this can be done quite easily with simple voltage dividers, and/or opamp buffers.
Thanks for the excellent and informative response -- quick too!
That cleared up a lot of things but I'm still scratching my head about
how to take an analog voltage and reading it from the beagle bone from
a language? (Any language is fine, I'm most proficient in python and C+
+ also NodeJS examples would help too but I prefer the latter if you
