A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
Teensy and Teensyduino
The Teensy is an USB development system, based on AT90USB162 AVR.
Image an Arduino "cousin" with built-in USB interface thanks to AT90USB162 microcontroller... Do you have it? Fine, you've got the Teensy!
The Teensy USB Development Board is a complete USB-based microcontoller development system. You can use Teensy directly in a breadboard due to its size. All you need to use Teensy is the USB A-miniB cable.
Unlike the Arduino, which converts 38.4 kbps serial to USB, the Teensy has direct 12 MBit/sec USB access, so communications are sent and received at full USB speed.
Direct USB access is possible, so the Teensy is not limited to being only a serial-type USB device. It can act as HID, Mass Storage, or nearly any type of USB device. The Teensy also has a serial port. It is not connected the USB port and can be used separately.
The Teensy is available in the PJRC shop: [?https://www.pjrc.com/store/teensy.html Teensy]
They provided also Teensyduino. Teensyduino is a software add-on for the Arduino IDE, which adds the ability to build and run sketches on the Teensy. You can
