Sending signed message on CAN

[mskulkarni]

I'm using S32K148 controller. I want to send a 8 bit signed integer (-128 to +127). But the data type required for FCAN Send block in NXP MBDT accepts only uint8 datatype. 

Just wondering if there is any way to send signed integer over CAN ?

Thanks in advance for your help.
