Every Gumstix Overo computer-on-module COM has the same three connectors and each connector has the same signal pattern. Each Overo COM also brings a wide selection of signals to the two pin connectors located on the bottom of the computer-on-module.

Gumstix has posted a series of videos that provides an introduction to the features and set up of several Overo configurations. Anyway, thanks Hugo for your prompt and helpful reply! Many signals come directly from the OMAP processor, so qdc can read about the function by looking at the processor data sheet.

Here's a summary of the sampling rates that we obtained with other channels. This patch implements minimal MADC clock initialization. Basically you need to enable MADC support in your kernel config using make menuconfig, copy.

The signals on these pins include but are not limited to the following functions:. To assist customers in development of their a custom expansion board s compatible with and driven by an Overo COM, Gumstix makes the schematic of each expansion board available freely and without cost or licensing fees, via our website at pubs.

The Tobi has the same 40pin header as the Summit. Python — Hz, C — Hz 8 channels: Here you will find the models, schematics, and production references you need to create Overo-based products.

I don't know if the problem is a general udev issue or something in the madc code that got broken. Rgds Asoe Protect Gunstix Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

Won't have actual speed test results until we gumsstix there on our project though, probably a few weeks from now Hi Hugo, Thank you for your code sample. Each Gumstix Overo COM can fit on every expansion board of the Overo series, except with one or two exceptions noted on the product pages at www.

I've CC'd the gumstix mailing list as well; hopefully others might find this useful as well. ADCs definitely work correctly on 2.

A list of the expansion boards for the Overo series is available at the store. Full reference information is available in the Signals Document posted on this page.

I try the test program shown by Hugo ,following all the patches in kernel 2. Python — Hz, C — Hz 4 channels: Hi Hugo or anyone Attached is my test program to read from the ADC.

Thanks for any help. I'm trying to get the ADCs working. I would really appreciate any pointers as to where to start in order to adv the same.
