Amen! I've been thinking about something like this for years. My specific use case involves controlling radio transceivers. Right now I do this with assorted Arduino hardware that speaks GPIO and RS232 (mostly) to the radios, and RS232 to the upstream "controller" host. This burns through a lot of serial ports on the controller. What I would prefer is to have all those Arduinos connected to an RS485 multidrop, each exporting a 9p filesystem for the control interface. Shoveling the data around on the RS485 "bus" just needs a simple frame wrapped around the 9p packets that provides device addressing and a CRC. On the Plan9 side this just becomes another network type, with ndb handling the device addressing. As others have mentioned, having a native Atmel C compiler would be a real boon here, but there's no reason why this couldn't be done with an Arduino 9P library. I haven't investigated if such a thing exists, although I'm sure it does. --lyndon ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Ta4e584a373b05553-M7e3fd4de0f3c256df6dbd436 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
