ATmega644PA Datasheet PDF
I have been programming an ATMegaPA with avr-gcc and avrdude on linux for a little while with no problems. Application Notes Download All. The AVR device connects to the STK using an innovative routing and socketcard sandwich system, which routes daatasheet signals from the device to the appropriate In addition the Power Debugger has two independent current sensing channels for measuring and optimizing the power consumption of.
Buy from the Microchip Store. Thanks for that fuse calculator link, a great resource indeed. I hope we can offer you a warm welcome, but vatasheet question might be a dupe. Upgrading the Flash memory using a U-Disk. In Atmega644p View Datasheets. 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.
Wafer Level Chip Scale Packages. Email Required, but never shown. Atmel Studio – Software Development Environment.
Sign up using Facebook. Could it be that using avrdude’s definition for the P version of the chip rather than the PA version is the cause? Would I be able to do that with an STK? Sign up or log in Sign up using Google.
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. Any ideas as to why the chip is unresponsive? There’s also one here on Chiphacker see my comment. Sign up using Email and Password.
Conditional Assembly and portability macros. The chip would no longer communicate. For pricing and availability, contact Microchip Local Sales.
First, welcome to fatasheet site! Nope, your 0x63 setting on the lfuse byte has selected the internal kHz oscillator as the clock source. Scalar sensorless methods to drive BLDC motors.

It’s fantastic that you read the datasheet, and tried to calculate what you wanted yourself, but the tool makes it much easier. Software Framework – Getting Started.
Well until I decided to change some fuses. Calibration of the internal RC oscillator. Wear Leveling on DataFlash. Runtime calibration and compensation of RC oscillators.
Next time, this fuse setting calculator is a nice resource. Best practices for the PCB layout of Oscillators. BTW, what were the fuses set to before you made the change?
Multiply and Divide Routines. 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.
This is nice and low power, but it means that your programmer likely isn’t clocking itself slowly enough to program your device. I’m not familiar with either avrdude or the STK, but this is where your problem is coming from. Please contact sales office if device weight datasheef not available. In addition the Power Debugger has two independent current sensing channels for measuring and optimizing the power consumption of 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.
Enhancing ADC resolution by oversampling.
