[Paparazzi-devel] FTDI 5V 232-TTL cable? Netbook shutting off to protect itself?

[Adrian Lauf]

Hello all,

My Tiny 2.11 is working beautifully, and my airframe files are configured - servos are moving, and I'm almost ready to get into the air - following some additional tuning. I do have a question about using the serial interface. I have an FTDI TTL-T232R-5.0V cable that I was using with an Arduino setup. I purchased the Tiny from Chebuzz, and am using the 4-wire header for serial communications. I have tried: PPZ Black ground cable to the black ground cable on FTDI, the Orange 5V PPZ cable to the RED 5V cable on the FTDI, the Blue PPZ TX line to the Orange FTDI line, and the Green PPZ RX line to the Yellow FTDI line. As soon as I plug the USB portion into my netbook, the computer shuts off instantly, seemingly to protect itself from a short. PPZ continues to boot properly (so far). What am I doing wrong? I have seen others use a 3V3 cable, but the Chebuzz serial hookup does not presently have a 3.3V line, unless I add it. What should I do? I'd mess around until it worked, but I really don't want to destroy the board. Thanks,

-Adrian
