Hi all,

   

Sorry for the silly question, but is there anyway to get 3.3 volts out of the Vdd pins of the 5LP prototyping kit, or it is just possible on the Pioneer one?

   

I'm trying to make a interface to an I2C temp IC (PCT2075 of NXP) and i would like to fed it with the 3.3 volts.

   

Also a kind of advice about the library im making up, this is the first one i ever did haha. I don't know how to put code snippets here so find the files attached, i haven't finish the Doxygen documentation so ignore the comments, but the functions i tried are finished, if you have time take a look and i would like to have some feedback. Didn't use the I2C buffers because i want to make a easy to adjust to other uC like Kinetis or LPC, i don't know if those uC have one. (also i don't understand it very well yet.)

   

Will attach a example project when i finish the adapter pcb for the sensor.

   

Thanks in advance

   

Carlos

In general yes you can run the PSOC at 3.3 V (all I/O will be 3.3), or you

   

can power specific ports at their own I/O level.

Yes, they in general have across their families I2C capability.
