There are a few choices for a free flite programmer. 1. Build the ST7-STICK using the gerbers/schematic available on this website. 2. Build Flashbash - www.spen-soft.co.uk 3. Build the programmer/debugger mentioned in the apps note section of Softec's website. 4. Build the programmer mentioned in the ICC Protocol Ref Manual - available on this website. If you don't want to build one yourself, then you can buy the ST7-STICK from ST. Also have a look at the Softec solution - inDart. Hope this helps sjo [ This message was edited by: sjo on 28-09-2004 12:47 ]
