(Off List) Hi Tim, I contacted CrossWorks and explained my situation and they said that they were fine with my use of CrossWorks under those conditions so my download is in progress now. I didn't post this on the list because I didn't want to cause a flood of requests addressed t

Dear Eugene thanks for putting the .pdf in the files section. Are you going to add a description and the relevant code as well? If yes, may I suggest a folder for everything together..... Greetings from Andy Mathison [Non-text portions of this message have been removed]

Hello Chuck Could you report the results of your dialog with Crossworks? If you don't mind of course. Best regards, Eugene

This does not look like "real" device - more just a barebone attempt to make one. It really takes a lot to create power part of stepper controller. My suggestion would be instead of doing this all by youself - to buy few TB6560 chips (those are not expensive) and use those for yo

I agree. I like to expand my horizons in my hobby and my job - It is nice when they are so related to each other! :) For instance I thought that when Microchip came out with their 16 bit offerings they were "too little, too late". But with their PIC24 line I've changed my mind. T

It seems to me that if you've got all the power you need, you're nowhere close to running out of flash and you own and know all of the tools you need to work, you don't have the kind of volume that would pay back the investment in a lower cost or otherwise better solution, why ch

Hi Chuck, I have been and still am a bit fan of the AVR and use them for smaller control modules that I design. I do however have a controller that has an LCD and a number of interfaces, CAN, RS232, RS485, 4-20mA etc and I had to find a suitable processor for these. I stumbled ac

Hi! Your board looks like auto-routed :) As people said before: 1. your components are too near the borders 2. if it's possible try another placing of components: place all the connectors by sides of the board. 3. As I said before the routing seems to be not optimal. If you'll tr
