INT32U error

Hi all,

I'm hoping someone can help. Im tryign to get the code working from https://github.com/AppSaloon/ecu-can-bus-simulator/blob/master/Seeedlib-ecu-sim/Seeedlib-ecu-sim.ino however it shows an error when i compile

'INT32U' does not name a type

Can anyone help? not sure what the issue is.

Thanks,

Add this as the first line of the file:

#define INT32U unsigned long int
