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

As I’ve never used the device, I’ll defer to the many other threads where others have posted problems and solutions for AVR fuse settings. Multiply and Divide Routines.

In addition the Power Debugger has two independent current sensing channels for measuring and optimizing the power consumption of Thanks for that fuse dtaasheet link, a great resource indeed. Best practices for the PCB layout of Oscillators. Home Questions Tags Users Unanswered. For pricing and availability, contact Microchip Local Sales.

I have been programming an ATMegaPA with avr-gcc and avrdude on linux for a little while with no problems. In Production View Datasheets. Runtime calibration and compensation of RC oscillators. Calibration of the internal RC oscillator. Software Framework – Getting Started.

Buy from the Microchip Datasheeg. BTW, what were the fuses set to before you made the change?

Enhancing ADC resolution by oversampling. Application Notes Download All. Well datashee I decided to change some fuses. Any ideas as to why the chip is unresponsive? Sign up using Facebook. Post as a guest Name. This is nice and low power, but it means that your programmer likely isn’t clocking itself slowly enough to program your device.

Nope, datzsheet 0x63 setting on the lfuse byte has selected the internal kHz oscillator as the clock source. Next time, this fuse setting calculator is a nice resource.

And finally, What can I do to rescue my chip? Conditional Assembly and portability macros. Please contact sales office if device weight is not available.

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.

A complete starter kit and development system for the 8-bit and bit AVR microcontrollers that gives designers a quick start to develop code on the AVR, with advanced features for prototyping and testing new designs. Would I be able atmega64p4a do that with an STK?

The chip would no longer communicate. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

However, it will be difficult for you to brick your chip, because you’ve got the STK, which can do high voltage programming and rescue it from most situations. There’s also one here on Chiphacker see my comment.

Upgrading the Flash memory using a U-Disk. But, this is a different chip slightlydifferent fuse settings, and a different programmer, so I say we let it stand And I don’t have the rep to flag it. Could it be that using avrdude’s definition for the P version of the chip rather than the PA version is the cause?
