Here is a nice overview of PCB design concepts, in a very well written and understandable format that I came across. Found on: http://www.alternatezone.com/electronics/pcbdesign.htm (PDF file is attached.). See pp. 18-20 for power and ground plane discussions, per your questions. Good luck and keep ...

Folks, Thank you all for the excellent replies. Clearly there are several pathways, each with its benefits and demerits. I do know C and have coded projects in it before, but it doesn't have the elegance of BASIC, and, in particular, the power and support of ZBASIC. The project in question is basica...

Thanks Don. That's clever. If time, I'll try it in place of that from my preceding post.

ZBasic Native Code Compiler in the works?

In a post several months ago, Don seemed to hint at the development of a native-code ZBasic compiler. In ZBasic Language forum, post titled"Performance of For Loop versus While Loop", Don quotes (1/7/07, 15:08pm): The primary impediment to implementing this is that the AVR chip can't execu...

Possible explaination for Delay (0.001) in DS1302 routines

Hi Folks, I have recently been implementing the DS1302 routines by zbasicandy (thank you!) for an application, and have made some changes and additions. I'll try to post them when finished. Regarding the Delay (0.001) issue in the Get_Time_Date() routine, part of the problem may be that only seven (...

Thanks for the clarification, Don. I suppose these are some of the idiosyncracies of having two systems at work: the Atmel at the hardware level and the ZBASIC firmware layer on top of it. Thanks for clarifying this issue. Moving forward, I think I will take your suggestion and simply use the SetBit...

Another thing to look for in using CPUSleep() is to make sure to enable the sleep mode as well as set the particular sleep mode that you desire. In the mega32 chip, this is the most-significant-bit of the MCUCR register (bit 7, called SE [sleep enable] in the Atmel documentation). By default it is 0...
