AVR-Chat

I thought the emails were a bit harsh.
  Pretty much every group allows appended links but not outright advertising or inappropriate advertising in teh main body of the email.
   
  Given the PCBCAD software has been used for dozens of microcontroller projects then it is very relevant. An AVR would be pretty useless with a PCB to put it on.
   
  I have designed some pretty big boards with microcontrollers on them.
  I designed an add on for the Ford Escort Cosworth so you can modify the engine management. It add 50 BHP to the already 200BHP on the car.
  We used a PIC and an ASIC but wanted to test the basic theory using TTL logic first.
  The board used about 30 TTL chips and the PCBCAD software we had (Easy PC) was useless for placing the components.
  I had my own basic PCBCAD software and wrote an autoplacing algorithm for it and it worked great. Clearly there are n! possibilities for laying out n components.
  This could take forever so I settled on a swapping autoplacer that simply swaps 2 of the same component if swapping them improves the net length. I found with this I got massive improvements in net lengths. The PCB was about 18 inches by 18 inches.
   
  The microcontroller was used to try and stop people copying the ASIC.

I approved that message, and I didn't see anything inappropriate in the
link.
Many of the folk on this list have something to sell, and as long as it's
reasonably AVR/electronics related, reasonable mention of your products is
fine.

Ralph's devices are AVR based, and while I personally don't believe that the
things they are supposed to measure actually exists, but they are AVR based,
and are legitimate projects at least in as far as they are good design work,
and worth looking at from that point of view.

And I could be wrong.
