My first thought is "how much power does it waste when nothing is plugged in?" I like to be able to turn things off when they're not being used...
We are selling DS2482-x00 based masters for the RasPi.rmp wrote:Take a look at this project for example : http://raspberrypi.homelabs.org.uk/i2c- ... e-masters/
Well that's me having learnt something today then, I wouldn't have expected that to work!paddyjoy wrote:I managed to get this working reliably tonight by using a 1K pull up resistor
If you're using a DS2482 as your bus master then you don't need any pull up resistors on the data lines, it's only if you're using the kernel/GPIO driver that you need those.fcara wrote:DS18b20 sensors are connected to +5v and ground and their data lines have been pulled-up with 3 resistors (4.7kohm) .
I suspect that is simply a bug in the tutorial as the module on mine seems to be rtc-ds1307 too.dm314 wrote:Btw, why did the tutorial added just only "rtc-1307" to /etc/modules instead of "rtc-ds1307"?
Just curious, but rtc-1307 worked for me when I didn't have my current problem.
