I didn’t want to fiddle around with getting power to the Chumby, so the test is simply using my trusty old laptop and the EasySync adapter. Only the speedometer, the tachometer and the accelerator pedal position is attached because again I’m too lazy to fiddle with my cable layout and as such its connected to the Mazda HS-Can bus only rather than the MS-Can where the goodie trip computer information is contained.
Almost every concoction of technology is used ranging from CAN, USB, PHP, HTTP, Shared Memory, XML, Flash, to an obscure programming language called HaXe. Here is the result :-
The toys just keep coming in! Another one of those wallet killing impulsive orders whilst I was sick in bed last week just arrived today, a USB-CAN bus converter module by EasySync that promises a great interface and should work in Linux! This will give a little bump start to my Mazda CAN Bus / mChumby projects.
Note : EasySync UK’s online form doesn’t allow international shipping but a short E-mail or two managed that. There is a US subsidiary with US and international shipping, but the international shipping rates on the US site is plain ridiculous [$68USD to ship a $88 device to Australia].
Note 2 : I hear the interface is mimicking the Lawicel CAN-USB interface…only hearsay…
Plugged it in – didn’t work. Doh! Took a peek at the manual and website, nothing on Linux other than “Linux drivers provided”… So much for the marketing material, guess I have to try make it work myself. (Yes I got it working, read on for the quick run-down post aimed at helping others)
