Hi, Is there a way from a OTS board pair to read from the Robostix A2D ports? A stand-alone program running on the Verdex pro? Something like i2c-io, although for that I don't know if it is OE compatible, it's not in the delivered image, and the instructions for getting it were on gumstix.org, not .net, nor have I found usage instructions for it. Yet.

I haven't tried it myself, but I believe that to get values from the AD you will need to go through the ATmega128 on the Robostix. The AD-converters are connected directly to the ATmega128, and you could write a small program for the ATmega that reads AD-values and sends them to your Gumstix using I²C. Jostein A.

Yet. If you search through the archives (I use: <http://news.gmane.org/gmane.linux.distributions.gumstix.general> then you'll find that i2c-io is availble to be installed under OE, along with all of the rest of the robostix samples. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ |

Thanks, Jostein. Can anybody tell me (or link me) what the Robostix has in its as- shipped runtime image? Or how I would find out for my specific board? The Verdex Pro comes with a program named i2c that can read and write any address in the i2c space. Is this the Verdex / OE equivalent to what is called i2c-io in the gumstix.orgbuildroot system pages? Can I use it to read the ADC pins? I really need to get a proof-of-concept demo going soonest, before going through the agony of learning how to code and load and run AVR programs.

If you don't need the speed of I2C I have my gumstix reading a2d values over serial, it was very easy. I just modified the Flash-LED.c example to just loop through and print the ADC values every 100ms (it does this on boot, I just took out the rest of the code.) I programmed the robostix using uisp and then the program runs on boot of the robostix and I can read the outputs by just reading from /dev/ttyS2. You need to wire Rx0 to Tx5 and Tx0 to Rx5 on the robostix. |
