mikroC PRO for PIC32

MikroElektronika

271

The SPI module is available with a number of the PIC32 MCUs. The mikroC PRO for PIC32 provides a library (driver) 

for working with mikroElektronika’s CANSPI Add-on boards (with MCP2515 or MCP2510) via SPI interface.

Important: 

- Consult the CAN standard about CAN bus termination resistance. 

- An effective CANSPI communication speed depends on SPI and certainly is slower than “real” CAN. 

- The library uses the SPI module for communication. User must initialize appropriate SPI module before using  

  the CANSPI Library. 

- For MCUs with multiple SPI modules it is possible to initialize both of them and then switch by using the    

  

SPI_Set_Active

 routine. 

- Number of SPI modules per MCU differs from chip to chip. Please, read the appropriate datasheet before      

  utilizing this library.
