It’s fantastic that you read the datasheet, and tried to calculate what you wanted yourself, but the tool makes it much easier.

Wear Leveling on DataFlash. Best practices for the PCB layout of Oscillators. In addition the Power Debugger has two independent current sensing channels for measuring and optimizing the power consumption of.

Any ideas as to why the chip is unresponsive? Please contact sales office if device weight is not available. Scalar sensorless methods to drive BLDC motors.

Upgrading the Flash memory using datasneet U-Disk. Could atnega644pa be that using avrdude’s definition for the P version of the chip rather than the PA version is the cause?

The AVR device connects to the STK using an innovative routing and atmeha644pa sandwich system, which routes the datahseet from the device to the appropriate Atmel Studio – Software Development Environment. In addition the Power Debugger has two independent current sensing channels for measuring and optimizing the power consumption of Post as a guest Name.


I have been programming an ATMegaPA with avr-gcc and avrdude on linux for a little while with no problems. Software Framework – Getting Started.

Thanks for that fuse calculator link, a great resource indeed.

I realized after that the problem may have been that I set the bits for external clock rather than crystal oscillator but even with using an ATTiny to generate a 1MHz signal to the proper pin on my Mega, I still get nothing. Only show products with samples.

Email Required, but never shown. Runtime calibration and compensation of RC oscillators. BTW, what were the fuses set to before you made the change? A complete starter kit and development system for the 8-bit and bit AVR atmega644a that gives designers a quick start to develop code on the AVR, with advanced features for prototyping and testing datashfet designs.

And finally, What can I do to rescue my chip?


Conditional Assembly and portability macros. In Production View Datasheets. The chip would no longer communicate. Atmel-Integrating the Internet of Things. I’m not familiar with datasheeh avrdude or the STK, but this is where your problem is coming from.

Sign up using Facebook. As I’ve never used the device, I’ll defer to the many other threads where others have atmega644ps problems and solutions for AVR fuse settings.

Multiply and Divide Routines. There’s also one here on Chiphacker see my comment. Nope, your 0x63 setting on the lfuse byte has selected the internal kHz oscillator as the clock source. The device operates between 1.
