Bus Pirate Support / Custom voltage for UART with BusPirate 3.6
Hello everybody,

First, I am totally new to hardware testing. I try to read / search for a maximum resources on Internet but some are still obscure to me.

I want to interact with a chip through UART.
In the datasheet, the voltage domain is between -0.3 and 2.1V for RX/TX.

The BusPirate is able to use 3.3V and a "pullup". I read some docs but I have difficulties to understand exactly what it is and how to implement it ...

It means that I will not able to communicate with my chip with default voltage setting 3.3V ?
If not, how I can have a 2V source plugged into the BusPirate ?

Thanks!
