Check function of CAN modules #17

Found good test's to preform on the CAN SN65HVD230 transceivers. You can check for functionality by probing between ground and pin 5 which should be Vref(VCC/2) or around 1.65v when the module is supplied with 3.3v.

Found that the modules I was using didn't work and or were counterfeits. Have since ordered new ones from mouser for my lab, but we should still verify the state of the other can transceivers we have at the moment.

Soldered up and tested new modules they work. Have canbus operational on pi and stm32 modules.
