Hi Frederic, For sure, 1.2 MHz is way too fast for the FoxBoard I2C. Something must have gone wrong. There is a new I2C standard that defines speeds up to 3.4MHz, but even Philips is currently not able to get those high frequencies. That's why they are now indicating their fastest devices with FM (Fast Mode), being working at a speed of 1MHz... Regarding your first question: no, I didn't try out such thing yet, since I don't really need it immediately... The next devices to be tested which are on my list, are the TDA8444 (octuple 6-bit DAC), MAX7312 (16 bit IO expander), MAX7300 (20 or 28 bit IO expander). I assume you're using that AT thing in slave mode, right? Will see what I can do to check it, but no promises... ;-) Best rgds, --Geert
