#132246 - CAN bus controller Responding to: ???'s previous message |
David Smith said:
I'm looking to interface to a commercial vehicle's CANopen (IFM system) bus. My application is an on board weighing system that needs to simply 'squirt' 8 bytes onto the bus, twice a second for processing by others. The existing weigher is 8052 based and already has serial comms and around 20kB of spare app ROM - but very little RAM or XRAM spare. It's coded in assembler. Projected numbers are If you are using a modern 3V 8051 with SPI bus the MCP 2515 from Microchip is a possibility. It's a simple CAN controller that gives you 3 TX buffers and 2 RX buffers and is easy to control. We have a design with 2 MCP 2515's controlled by a Silabs C8051F120, it works fine. Lex. |
