With the arrival of the PIC18FXX8X family of microcontrollers featuring the
Enhanced Control Area Network (ECAN) module, designers can now choose between
the original CAN module present in the PIC18FXX8 family and the new ECAN-enabled
parts.
This application note presents communication time comparisons along with conclusions
and recommendations intended to help designers find the best CAN-based solution
given an application and available parts.
These comparisons and related recommendations are based on the following rules:
- Code processing time measured in number of instructions (assembly language)
- Transmission and reception times measured in bit time
