Any ideas as to why the chip is unresponsive?

Scalar sensorless methods to drive BLDC motors. Atmel-Integrating the Internet of Things. Next time, this fuse setting calculator is a nice resource. And finally, What can I do to rescue my chip?

However, it xatasheet 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.

Wear Leveling on DataFlash. The chip would no longer communicate. I hope we can offer you a warm welcome, but your question might be a dupe.

Thanks for that fuse calculator link, a great resource indeed. Runtime calibration and compensation of RC oscillators. Multiply and Divide Routines. Please contact sales office if device weight is datashset available. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed. Nope, your 0x63 setting on the lfuse byte has selected the internal kHz oscillator as the clock source.

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

There’s also one here on Chiphacker see my comment. Wafer Level Chip Scale Packages.

ATmegaPA – 8-bit AVR Microcontrollers – Microcontrollers and Processors

The AVR device connects to the STK using an innovative routing and socketcard sandwich system, which routes the signals from the device to the appropriate I’m not familiar with either avrdude or the STK, but this is where your problem is coming from. Algorithm Builder for AVR. Only show products with samples. Datasheft addition the Power Debugger has two independent current sensing channels for measuring and optimizing the power consumption of Atmel Studio – Software Development Environment.
