LEDs visible through the translucent case indicate the state of target power. In such occurrences, a programmer capable of sourcing greater current is required. There are also a number of 3rd party clones available. There is no area for any additional circuitry, although this can be provided by a third-party product called the "Dragon Rider". The debugWire interface enables debugging using only one pin the Reset pin , allowing debugging of applications running on low pin-count microcontrollers. The board includes the LCD screen, joystick, speaker, serial port, real time clock RTC , flash memory chip, and both temperature and voltage sensors.

I started to write code using atmel studio ide but i found it very hard to work with the atmel studio ide. Atmel studio is slow and finding bugs etc are also very difficult. So i decided to switch to the arduino ide. Some body added Atmega support to arduino ide, so i utilized it.
In order to install the atmega support to your arduino ide please see my post. So i decided to ope-rationalize the atmega microcontroller uart by individual register configuration. In uart. Almost all the atmega series microcontrollers uarts are initialized using the same registers, the registers are same for almost all the microcontrollers.
I copied the initialization code from there. Atmega uart initialization, register values calculation formula. Its a 16 bit register. In order to set the desired baud rate. We have to calculate the value for this register. The formula for calculating the value is given on right side. I am using uart-0 for this post. You can use the uart-1 if you want. Uart-0 is at pins 10,11 and Uart-1 is at pin 3,4.
In the demo project i initialized the baud rate to I am sending my website name from atmega serial port to my pc personal computer. For viewing the output on my computer i am using an putty. It blinks after every second. Shows the program status, if the hardware is working or not. Note: The led is connected to pin 25 where as in code its declared as pin 22, its because for programming the pins are assigned different numbers.
Remember the upper tutorial see that for more clarification. Download the project. Code is written in arduino ide. Please provide us your feed back on the project. Watch the Project Video Here. More Projects on Serial Uart Communication using different types of microcontrollers. Each project contains free source code and circuit diagram of the project.
