I'm trying to talk to a motor controller which accepts 1-byte serial commands. I didn't want to use a microcontroller because I need to really conserve weight. Brian Gregory Hi Brian, > How can I send serial on a GPIO? (The equivalent to the "serial" keyword on > a basic stamp). I hate to tell you this, but you're going to find this very hard to do. On a Basic Stamp, performing a serial keyword basically consumes 100% of the CPU. You could theoretically do this on a gumstix as well, but it would require writing a special kernel driver. You also wouldn't be able to use it for sending/receiving very much data. And everything else on the gumstix would grind to a halt whle this is happening. You'd be much more likely to get something like this working on the robostix.
