Very interesting Dave. The propeller is a very cool gadget. I think the Ardunio has a big following as well but I’ve not played with that as getting an AVR to talk is pretty easy now. The Mikroe dev board + compiler is not perfect – but it’s pretty simple to get working. And for

It is usually a good idea to following some sort of programming template as well, i tend (not always) to follow the MISRA C programming guidelines as to structure and technique, it enforces good programming techniques amd just as importantly design methodology and documentation.

Hi there, Looking at the delay functions, I see that: void _delay_us ( double __us )has a maximal possible delay is 768 us / F_CPU in MHz. But:If the avr-gcc toolchain has __builtin_avr_delay_cycles(unsigned long) support, maximal possible delay is 4294967.295 us/ F_CPU in MHz. H

Hi Jeff, At one time, I belonged to a robotics club in Roseville. The AVR and the Propeller were the two most popular chips. The Propeller with 8 cores was a dream for robotics. I was one of 26 folks around the world to be on the beta test team for the Propeller. I did these prog

Gidday, I was going to upgrade my STK500 to a STK600. But I then became aware of the development boards from "Mikroe Electronics". Specifically the "EasyAVR6" and the "BigAVR6" development systems, they seem to be ideal for a home hobbyist who wants to concentrate on the software
