hello,

I’m doing my project in a wireless communication, i want to send some data using the Xbee transceiver, in one side i have some sensors and the Xbee connected to the PIC16F877A.and in the other side i want to connect it to the PC to receive display the data, do i need a PIC to send the data received from the Xbee to the computer? or is it possible to connect the Xbee directly to the serial port using max232? i found this web

Thanks!

You can use a max232 to connect directly to the PC.

Use a 3v tolerant version of the MAX232 as the XBee is a 3v device. You don’t want to connect the XBee directly to the PC. Go to the Sparkfun catalog page and check out their level converters.

thats a good point i forgot to mention.

Ive even had success using a 7104 TTL hex inverter running at 3.3V (out of spec) when i was desperate and dident have any 232 chips around.
