Hi every body I'm going to create a ARM board with these features: 1. ARM micro-controller (which supports WINCE) 2. A touch LCD 3. 2 sign LED 4. 4*4 keypad 5. USB (for install WINCE on ARM => or maybe another connector be used ) As you know the ARM frequency is around 2GHz and designing board in not like AVR board. Actually I don't know what is the designing deference between ARM board and low frequency boards. I was wondering if you help me. Thanks
desigen ARM board
There is a great high speed design overview using Altium Designer that might be useful for you. http://www.fedevel.com/welldoneblog/wp-content/uploads/2011/06/HiSpeedDe... If you have only done simple AVR board then a full blown high speed ARM on multilayer (6 or 8) is going to be a challenge and you will need to learn quite a lot. I am looking to do this myself in the next few months and the above document is very helpful. Good luck with your project. Dave...
