	Talking to robostix from gumstix by gordu :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi all I have tried talking to my robostx on its UARTs every way I can think of. I have tried using a serial adapter (on both uarts) and I have tried bridging the gumstix/robostix uarts together as mentioned on the robostix ISP page and then using minicom on the gumstix as well as Dave H's sertest. With the i2c-io program of Dave's I would expect to see some output but nothing. I do have some form of connection because as soon as I hit return in either minicom or sertest the i2c-io program on the robostix stops blinking the LED. Anybody know what I've missed? thanks gord u ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

So just to clarify - you're trying to use i2c-io and you want to use it to send some data out the robostix uart? Looking at the i2c-io code, it appears to initialize UART-0 to 38400 baud and sets up the interrupt handler, but doesn't do anything with the received characters. It appears that the interrupt handler will grab any received characters and shove them into an internal circular buffer, but nobody is reading that. I'm a little surprised that the LED stops blinking. If you set IO_LOG_ENABLED to 1 in the robostix/i2c-io.c file (and rebuild/redownload i2c-io.hex), then it will print some stuff on UART-0 at bootup. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
