File for atmega128

The quick setup had been tested under Windows 10 x64 and under Windows 7 x The quick setup had been tested with Atmel Studio 7 , If the Olimex instructions for the Olimex product you have purchased don't work, you should contact Olimex!

Some pins are able to perform more than one functions on each pin. ATmega can perform a number of functions on a single chip.

Large memory space with more number of pins interface put this device ahead of other controllers available in the AVR community. Atmega comes with four timers i. These timers play a vital role in creating a delay of any running functions and can be used both ways i. Two other timers added in the device are. Oscillator start-up timer resets the controller to stabilize the crystal oscillator. And power-up timer is used to generating a minor delay once you power on the device, helps in stabilizing the power signals.

The BOD, also known as BOR Brown Out Reset , is a valuable addition to the device that helps in resetting the module once the Vcc voltage supply goes below a brownout threshold voltage.

In this mode, multiple voltage ranges are produced to save the module once the power drops at the voltage supply line. If you aim to bring back the device from BOD function, it is advised to enable the Power Up Timer for creating a slight delay. Most of the chips, if not all, produced by Microchip, incorporate a built-in watchdog timer that resets the controller if the running program hangs up during compilation or gets stuck in the infinite loop.

The main purpose of this timer is to prevent the controller from resetting it manually, giving you a slight edge over other processors where you need to wrestle your mind to manually reset the controller in case there comes a glitch in the running function.

The watchdog timer behaves like a countdown timer. The interrupts are very helpful for calling the desired function that puts the main running function on hold until the required instruction is executed. The controller goes back to the main program once the interrupt is executed. It is a two wire communication that mainly contains two lines. The former is a clock signal, mainly used to synchronize the data transfer between the devices and is generated by the master device, while the later is used to hold the desired data.

ATmega houses a serial peripheral interface SPI that is mainly used for communication between the microcontroller and other peripheral devices such as sensors, shift registers, and SD cards. But I am not getting output that should be. So I want solutions of above mentioned problems. Please help me to solve this out. FenTrac Full Member level 4. If you are using the Arduino IDE to compile the program, you will have to create a pins.

Thanks for respond. What is pins. Is it available on google or I have to create? Can you create for me? And where this file would be located after creation?

I know about board. But have confusion that which board of arduino have atmega? Because in first line of board. What's about it? Kindly reply to these problems. What GLCD are you using? The arduino software has them in arduino-1,0. They map the pins of the chip and board, so there is one for each arduino variant such as mega, leonardo etc, You might be able to find one on the internet.

I found some for the ATmegaP at one time. I will post the code here and can you please do it for me? Draw the Circuit using Proteus and post it here. Use it and make the circuit. I will port the code. Hey Thanks man, I found and I have done it. I just copied the text in separate text file in my laptop and then done as directed in other website. I do not have tested yet but I think it may work definitely.

If any issues will be there related to this board. ANyway, thanks a lot for helping me. Its too easy. Thanks again.
