WebCan bus converter SPI communication . Hey guys, I need your help. I'm trying to make a steering wheel that communicates with the ECU via an Arduino and a CAN bus converter module MCP2515. The clock speed is 16MHz and the bit rate is 500kbit. When I connect the CAN module and the Arduino directly, everything works fine.

WebSPI. SPI (Serial Peripheral Interface): The synchronous serial bus method proposed by MOTOROLA. High-speed synchronous serial port. 3 to 4 wire interface, independent … The biggest difference between CAN and SPI is that the CAN protocol defines packets. In SPI (and serial interfaces in general), only the transmission of a byte is fully defined. Given a mechanism for byte transfer, software can provide a packet layer, but no standard size or type exists for a serial packet. See more When I want two identical processors to communicate, I like to express messages as structs. For example, a setting message could be … See more Controller Area Network (CAN) is a multi-drop bus protocol, so it can support many communicating nodes. 1The advantages are obvious.

WebTypical SPI can easily run at 4 Mbps. Some applications require high speed transfer over SPI. For example: SD cards, radio comms. A bit-banged SPI would be too slow. As a result, the SPI would have to be implemented with hardware MSSP, and the slower I 2 C would be implemented in software. Sometimes the speed is not important. mobwork appWebSPI Mode: Polarity and Clock Phase.
