I bought a new STK500 starter kit and the "Embedded C Programming and the Atmel AVR" book last week. I have the attached the STK500 and it downloaded the firmware update with no problems so I know the connection works. I'm working through Appendix B "Getting Started with CodeVisi

Dear, If i want to control output pulse frequency, how can i do? I have a idea , maybe i will use timer0 interrupt to control. This project is very simple to use ATtiny13. Please tell me good method , thanks a lot. Luke.

There are two address spaces. One is for IO and certain IO instructions (such as "IN" and "OUT") work in that space. The other is the general address space in which all instructions work. They give you both because every once in a while, there is something you just can't do with
