Hi All. I used Atmel 8051 derivatives in all my earlier projects. Atmel made a really nice chip in the AT89C55 then later they changed the die and it was not as good; chip 'engineers' come along and change a tried and true chip and its specs change and then it does not work properly anymore. EG CD40106/74C14 performs totally differently than the original National Semiconductors CD40106....

Hi, Just wondering if it is worth forking out for the Lauterbach debugger/ICE or to settle for something like OpenOCD + Amontec JTAGKey to debug an Atmel SAM7 MCU please? Basically I'd like to be able to set breakpoints in my IDE (Eclipse or Xemacs) and if possible, view contents of registers/RAM etc. Thanks very much. PretzelX.

I've been using DES bootloader from atmel app note for a while. The problem is that occasionally my mega8 locks up. It will still accept and complete upgrade, but the application will simply not run any more. I have to re-program the boot loader to make it work again. Does anyone have experience with this kind of behaviour? Someone on avrfreaks hinted that there was a problem and linked...

I just started developing programs on Atmel's AT91EB42 evaluation board using CrossStudio, which uses GNU toolchain. Two days ago I noticed that after my program was loaded into SRAM and started running, the board would reset itself after about 5 minutes. The program can be as simple as an infinite empty loop and the reset would still happen at roughly the same time. Initially, I thought it ...

Anyone have any comments on the feasability of connecting a Atmel AT90USB128 (which has usb host mode interface) to a 802.11g USB adapter based on something like the Zydas ZD1211? Seems like it could be a cheap and flexible solution-- but quite a bit of work, and would require a USB analyzer. The ZD1211 is supported by linux, so that would be a good reference, and Atmel provides a simple...
