HI,
I’m not sure if hardware is the right category for this, but I have a question about the spark. I read in the documentation on the processor that it supports the CAN protocol. Does anyone know if that means the spark also supports it without any additional hardware?
Thanks!
The TX and RX pins for CAN on the STM32 is used in the 
core as the onboard USB interface. The 2 pins are not directly exposed on the board and the only way to tap it is through the resistors connected to the pin.
I think a CAN-BUS shield would preferred…
Right, that would work. Thanks for the prompt response!
