Driver CANFD controler on SPI bus

[raf6410]

Hi,

I would like to add some extra CANFD channel via SPI on my custom board. The controleur CANFD is MCP2518FD. I would like to have driver bloc in Harmony 3. I tried to understand how it make but i'm a newbie in harmony.

Could you help me ?

Hi,

Harmony 3 supports CAN/CAN-FD PLIB (Peripheral Library) only for on-chip CAN/CAN-FD controller for Microchip 32-bit MCU/MPU devices. As per requirement, The following option can be considered to add external CAN-FD controller via SPI (SPI to CAN-FD) using MCP2518FD:

• Create MPLAB X Project using Harmony 3 configurations and add H3 SPI Driver in the project.
• Develop SPI to CAN-FD Application using H3 SPI driver to interface with MCP2518FD as per project requirement (Reference example code which can be helpful for developing SPI to CAN-FD application - https://ww1.microchip.com/downloads/en/DeviceDoc/mcp25xxfd_demo_h2_rel.zip)

Thank you.

Thanks for your help.

In using a custom board with a DsPIC32MK. I'm already use the 4 CAN channels inside the PIC. I know this exemple, i have already tried to merge this exemple with my code.

Other question, How "harmony communty" choose new driver to add ? For exemple, if i would like to create a driver " External CANFD controller" I can push here myself or it will be "Validate" by Harmony community"?
