The Pololu USB AVR programmer can be used in Linux to program AVRs and to send and receive bytes on the USB-to-TTL-serial adapter.
The configuration utility is written for Windows; there is no Linux version. All of the parameters that can be set in the configuration utility are stored in persistent memory, so Linux users only have to use Windows when they want to change those parameters, which should not be too often.
The SLO-scope client is written for Windows, and there is no Linux version; Linux users are unable to use the SLO-scope at this time.
If you would like to write a configuration utility or SLO-scope application for Linux, you can contact us for information.
