Not much to go for with just that description. Could you explain more about how you have connected the MCU in the board and what programs you use? Are you aware of that the do not have an internal RC-oscillator? It is that have that. Don't apologize for your English!
Believe me it is much better than many people I have been around and I am American. I'm seem to have the same problem. I'm using AVR Studio 3. Did I forget something the handbook mentioned? The STK does work with the that came with it, no problem. I tried two s, but to no avail. The errata sheets mention a couple of problems, but none of it seems to be related to this one.
Scanning Atmels FAQ wasn't helpful either. Missing RC-Oscillator - doesn't the board supply the clock? There are a few more connections to make with this method of programming using the 8 pin sockets but it will probably enable you to program the chips. Hope this one helps. The need to connect a clock signal can be found in a single sentence in the setup instructions for high voltage programming with the STK, but it is missing in the ISP setup The similar reset signal IS discussed there.
Of course it is possible to conclude all consequences for the boards design from the differences between the and the , but then again, this is a starter kit.
It works now. Thanks a lot again. Skip to main content. Log in or register to post comments. Go To Last Post. Level: Hangaround. Posts: View posts. Posted by Tobiase : Fri. Sep 7, - PM.

This is a list with some 'bugs' on the AT90S perhaps, you'll find there an important info to handle yours problem sorry for my terrible english regards sven.
Hi Sven, Don't apologize for your English! Best regards, nuttall. Posted by admin : Thu. Oct 11, - PM. Hi everybody, I'm seem to have the same problem.
What's wrong? With me, the board, the chip, the world? Any idea? Yours, Bernd L. Posted by derek : Thu. Level: Rookie. Posts: 21 View posts. Posted by rm : Fri. Oct 12, - AM.

The AVR core combines a rich instruction set with 32 general-purpose working regis- ters Ground pin. The Port B output buffers can The ALU supports arithmetic and logic functions between registers or between a con- stant and a register. Single register operations are also executed in the ALU. In addition to the register operation, the conventional memory addressing modes can be used on the register file as well.
All rights reserved. The AVR core combines a rich instruction set with 32 general purpose working regis- ters. All the 32 registers are directly connected to the Arithmetic Logic Unit ALU , allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
