2024年1月31日 · CAN Bus is a small-scale networking standard, originally designed for cars now used for many robotics or sensor networks that need better range and addressing than I2C, and don't have the pins or computational ability to talk on Ethernet.

2024年1月31日 · Using the CAN Bus BFF with Arduino involves wiring up the BFF to your Arduino-compatible QT Py or Xiao form factor board, installing the Adafruit_MCP2515 library, and running the provided example code. In the example below, you'll connect a RP2040 CAN Bus Feather to a QT Py plugged into a CAN Bus BFF.

2024年1月24日 · Each CAN devices sends messages whenever it wants, and thanks to some clever data encoding, can detect if there's a message collision and retransmit later. If you'd like to connect your QT Py or Xiao to a CAN Bus, the Adafruit CAN Bus BFF will work with any and all boards thanks to the simple SPI interface!

2024年6月3日 · It's easy to use the CAN Bus BFF with CircuitPython and the Adafruit_CircuitPython_MCP2515 (https://adafru.it/18Bm) module. This module allows you to easily write Python code that lets you utilize the MCP25625 CAN bus controller. In the example below, you'll connect an RP2040 CAN Bus Feather to a QT Py plugged into a CAN Bus BFF.

2024年4月16日 · CAN Bus is a small-scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C, and don’t have the pins or computational ability to talk on Ethernet.
