I'm a newbie and I'm trying to communicate with a Xbee module thanks to my LPCXpresso board using a UART. The chip on my board is a lpc1114. I am currently facing some issues when sending data. The TXD pin is continuously at a high level. I was wondering if it could be due to the output voltage which could be too low (it must be at least 2.6 V for Xbee input). I'm  using  code inspired by the UART example and it worked once...

Thanks for any reply!
