Thanks for reply. I would if I could. I'm a user as opposed to a developer.
The analogue input feature(s) are planned for RTB but as yet are not forthcoming. They appear to be implemented in FUZE BASIC (for the Raspberry pi with (presumably) additional a/d hardware).
FUZE BASIC is a free download for the Pi but I need to know what a/d hardware they are using and how it interfaces with the Pi (I2C, SPI etc). I haven't yet asked the FUZE people but I suspect they would be reluctant to release any detail of their product for commercial reasons.
thanks again
