Right, it 9-12 for syncSubmit(). To complete an I2C read operation (1 byte of I2C data) you'll need 4 of such syncSubmits or 48ms. Higher level app may need to read 20 bytes over I2C as a full telemetry packet which adds up to 80 synchSubmits or 960ms. > > -- > Dan Streetman > [EMAIL PROTECTED] > --------------------- > 186,272 miles per second: > It isn't just a good idea, it's the law! > > > > ------------------------------------------------------- > This sf.net email is sponsored by: See the NEW Palm > Tungsten T handheld.
