mikroBASIC
- Basic Compiler for Microchip PIC microcontrollers
CAN (Controller Area Network) module is available with a number of PIC MCU
models. mikroBasic includes a set of library routines to provide you comfortable
work with the module.
CAN routines are currently supported by PIC MCU models P18XXX8.
Microcontroller must be connected to CAN tranceiver (MCP2551 or similar)
which is connected to CAN bus.
The Controller Area Network module is a serial interface, useful for communicat-
ing with other peripherals or microcontrollers. Details about CAN can be found in
appropriate literature and on mikroElektronika Web site.
Following routines can be considered a driver for CAN module on PIC MCUs.
