hello; I am interested in connecting several accelerometers to an atmel
and maybe using a processor that supports USB. I found an accelerometer
that uses SPI bus.... In my case it's a ST LIS3L02DQ.
Which can speak SPI as well as I2C.
I have a lot of experience using the LIS3L02DQ and their
ilk with the AVR, most all of it *bad*. DO NOT use the 302
on the AVR SPI bus, you won't like the results.
What about having the LIS3L02DQ's VDD provided by one of the AVR's I/O
pin? This way one will activate the LIS3L02DQ under application control,
not when the chip is being flashed.
