I think this data is all on the Atmel website. They have a spreadsheet listing that shows how many of each feature a particular chip has. Take a look. Zack On Mon, 3 Mar 2008, eko setiawan wrote: > anyone know about Atmel which include feature 4 timer/counter. > cause i will use
2008-03-04 by Roy E. Burrage
The selection guide at the Atmel web site has an in-depth table with all major peripherals listed for comparison. Actually, depending on your speed of operation and number of other functions required, you could use about any of the controllers if you get your firmware right. REB

That would be quite an adventurous project. The programmer contains a programmed 90S8535 and a programmed 90S1200, both SMD on the double-sided board of the real STK500. How are you going to program them if you don't already have a programmer? Can't you buy one? Zack On Sun, 2 Ma

This is due to the way C is parsed by the compiler. The compiler throws a wobbly even in Visual C if the braces are unequal. It goes to the end of the file if there is one missing. ----- Original Message ---- From: avrx123456789 To: AVR-Chat@yahoogroups.com Sent: Thursday, 28 Feb
