Crate mcp25xx 

no_std library for the MCP2510, MCP2515 and MCP25625 CAN controller chips.

API is implemented in terms of of the embedded_hal and embedded_can traits.

Activating the mcp2515 or mcp25625 feature will enable additional registers and instructions the MCP2510 does not support.

Example

use embedded_can::nb::Can;
use embedded_can::{Frame, StandardId};
use mcp25xx::bitrates::clock_16mhz::CNF_500K_BPS;
use mcp25xx::registers::{OperationMode, RXB0CTRL, RXM};
use mcp25xx::{CanFrame, Config, MCP25xx};

// spi is a struct implementing embedded_hal::spi::SpiDevice.

let mut mcp25xx = MCP25xx { spi };

let config = Config::default()
    .mode(OperationMode::NormalOperation)
    .bitrate(CNF_500K_BPS)
    .receive_buffer_0(RXB0CTRL::default().with_rxm(RXM::ReceiveAny));

mcp25xx.apply_config(&config).unwrap();

// Send a frame
let can_id = StandardId::new(123).unwrap();
let data = [1, 2, 3, 4, 5, 6, 7, 8];
let frame = CanFrame::new(can_id, &data).unwrap();
mcp25xx.transmit(&frame).unwrap();

// Receive a frame
if let Ok(frame) = mcp25xx.receive() {
    let _can_id = frame.id();
    let _data = frame.data();
}
