Programming Hack Without Computer,So Amazing!

Recently ,I have heard a word,which makes me amazing,that is computerless Arduino programming hack.

Teague Labs has developed a device for programming and altering the code on Arduinos without the need for a computer. This opens new opportunities for in the field programming and testing of Arduino projects.

The Computerless Arduino consists of two major components; an Arduino-compatible microcontroller loaded with a realtime code interpreter, and a stand-alone 5 button LCD display to display port values and manipulate code. The display can be connected to the Arduino via a 4-pin port at any time to peek at In/Out values, view the current code, and make changes as desired.

Attaching A Multiply 12C To The Bus

12C is so popular,and it has a wide use.Now with the efforts of some engineers,it can been also used in a common bus.

You can buy varieties of I2C compatible devices in the form of temperature sensors, serial EEPROMs, real-time clocks, LCD drivers, port expander, and so on. While most modern microcontrollers do have built-in I2C communication port, it’s implementation requires a good understanding of the protocol in general, its signal types, and an addressing scheme for uniquely identifying multiple devices on a common I2C bus. Embedded Lab’s new tutorial on I2C communication covers all the detail that is required for connecting multiple devices on a common I2C bus.

The tutorial uses PIC18F2550 microcontroller, to which are connected three I2C compatible devices: 2 EEPROMs (24LC512) and 1 temperature sensor (DS1631).
