Teensy is a line of hardware boards designed to offer maximum I/O capabilities, backed up by a slew of fully featured software libraries designed to run on Arduino. The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. The Teensy boards are fully compatible with Arduino Software & Libraries. Most programs written for Arduino work on Teensy. All of the standard Arduino functions (digitalWrite, pinMode, analogRead, etc) all work on Teensy. Teensy has the same built-in peripherals as the Arduino: analog inputs, SPI, I2C, PWM, and a real serial port.
CAN FD, compared to Classic CAN, provides increased bandwidth within automotive and industrial networks. The CAN FD protocol has taken application software closer to "real-time" by minimizing delays between instruction and transfer of data (latency) and higher bandwidth. CAN FD provides more storage capacity in the Classic CAN Bus data frame. While Classic CAN holds 8 bytes of data within a data frame, CAN FD holds up to 64. This is achieved through a decrease in relative overhead and improvements to software simplicity and efficiency when transmitting large data objects. CAN FD also has reduced the number of undetected errors by increasing CRC-algorithm performance. CAN FD has been estimated to transmit data up to 30 times faster than classic CAN.
The Teensy 4.0 (installed) board comes with a CAN2.0 (Classic CAN) or CAN FD port. It includes a 480x320 3.5" capacitive touch screen with ILI9488 LCD controller. Connection to the Teensy is via SPI running at 60MHz. The board can be powered through the Teensy's USB port or via an external 7 to 24 VDC power supply connected to the onboard SMPS (Switch Mode Power Supply).
