Awesome. My initiative : to be able to squeze out more info from the Prius than it is given on the standard display… Such as amperage used, longer term MPG computation and more.. a Zaurus SL-C700, running Linux Embedix, I ported one of my codes… ( I modified the Zaurus sync cable to accept serial input, the code is reading the CAN232 on 115.2KBaud with acceptance filtering to reduce traffic, data is collected, analysed, prep’d and written to the Linux framebuffer.) .
