Understanding Teensy 3.6

The Teensy 3.6 is a 32-bit Arduino compatible development board that aims to bring ARM Cortex processing power into a breadboard-friendly package for hobbyist use.

 

Powering your Teensy 3.6:

There are three ways of powering your Teensy 3.6 development board:

  • Using the built-in USB micro connector.
  • Supplying a voltage of 3.6V to 6V from an external supply, possibly a 5V regulator. This method is recommended.
  • Supplying 3.3V directly to the 3.3V pin. This method is not recommended since the supply line is directly connected to the microcontroller, any spikes or ripple might lead to damage.

 

Input/Output: 

The Teensy 3.6 has 62 GPIO pins with a current sink/source ability of 25mA. Pull-up resistors can be enabled on the pins.

Most pins have extra functionality as well:

  • Serial ports – receive and transmit data via the UART protocol
  • I2C ports – two-wire communication via the IIC protocol
  • SPI – fast serial communication
  • PWM – output an 8-bit pulse width modulated square wave
  • Pin 13 has a built-in LED

These special functions and their respective pins are illustrated in the Teensy 3.6 pin diagram shown above.

 

How To Use The Teensy 3.6

The Teensy 3.6 can be programmed using any C editor or the Arduino software, though the latter is quicker and easier for beginners.

The Arduino software download link can be found here:

https://www.arduino.cc/en/Main/Software

Once the software is downloaded and ready, the Teensy 3.6 is connected to the computer through the USB micro port.

 

Uploading Your First Program:

Select the correct board name (Teensy 3.6) in the Tools > Boards menu and select the correct COM port under Tools > Ports.

Since the built-in LED is on pin 13, just like the Arduino, the basic blink sketch will work on the Teensy 3.6. The code is shown below.
