Introduction The CAN bus was developed by BOSCH (1) as a mufti-master, message broadcast system that specifies a maximum signalling rate of 1 megabit per second (bps). Unlike a traditional network such as USB or Ethernet, CAN does not send large blocks of data point-to-point from node A to node B under the supervision of…
Overview communication between the MCU controller and external peripherals or another controller. Typical applications include external I/O or peripheral expansion with devices such as shift registers, display controllers, and analog-to-digital converters (ADCs). Communication between multiple devices is supported in SPI master or slave mode. The port supports 16-level receive and transmits FIFOs to reduce CPU…
