CAN-BUS Shield testing with only 1 shield

-

so after getting solder elecfreaks can bus shield connected , uploaded same receive check sketch, opened serial monitor , got instant:
can bus shield init ok!

but realized have 1 shield, there anyway test setup without shield? sample receive_check sketch can go out car , connect device , watch serial monitor data?

i doubt simple, haven't found source setting , testing 1 shield alone.

i have other dev boards have can bus, cypress psoc boards , not sure how easy or hard connect this..

a can bus not work single node every message sent needs acknowledge @ least node in bus.

some controllers offer "loopback" mode, popular mcp2515, 1 you're using... have on datasheet how enable , use (http://ww1.microchip.com/downloads/en/devicedoc/21801e.pdf page 58).

another option plug scope can lines , see if message being transmitted , decode see if expect.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
