Confirm that you can compile and upload the classic blink sketch to the Teensy board. Teensy 3. From the Tools menu, select BoardTeensy 3.2 and CPU Speed72 MHz (and whatever optimization settings you’d like).

21x High Resolution Analog Inputs (13 bits usable, 16 bit hardware).

Teensy 3.2 + header - General Specifications Although the Teensyduino IDE has been adapted so that many simple Arduino projects will work with the Teensy, there will still be a lot of libraries and shields that will not work with this device. Note: Teensy 3 and 2 are not official Arduino-brand products. This board has the same size, shape and pinout as well as full compatibility with all shields and add-on boards made for the Teensy 3.1, plus double the Flash memory as the Teensy 3.0.

I'm not sure what the root cause is of this, but to make it easier I've put a separate jumper on the power pin from the teensy to the SOIC chip. If I cycle power to the chip a few times it starts to respond.

This latest version of this complete USB-based microcontoller development system now adds a more powerful 3.3V regulator, as well as accepts a wider voltage input range. Sometimes the SPI flash chip doesn't respond to the i command - the result comes back as all 0xFF. version of the Arduino IDE (Teensyduino) or programming directly in C language. Teensy 3.2 brings a low-cost 32 bit ARM Cortex-M4 platform to hobbyists, students and engineers, using an adapted version of the Arduino IDE ( Teensyduino) or programming directly in C language. Teensy 3.6 brings a low-cost 32-bit ARM Cortex-M4 platform to hobbyists. Teensy 3.2 is a small, breadboard-friendly development board designed by Paul Stoffregen and PJRC.
