Hi all, I received several free sample ICs at home and I decided to use them with my Mini 6410. I connected the I2C bus to a Maxim MAX520 (DAC Chip) and I wrote a simple user-space C program to program it. I wrote a post on my blog to show how I connected the SDIO to a breadboard and which kind of test i did. You can see the post here http://www.sereno-labs.com/Using_Mini_6410_I2C_bus_with_Maxim_MAX520 I would like to know if someone is doing tests like me with I2C peripherals (DAC /ADC /GPIO extensions and so on) to exchange ideas and opinions about the chips. Keep in Touch! Paolo
