#170934 - Woops. I was half asleep. Responding to: ???'s previous message |
Sorry I was half asleep when I edited my last post and wrote:
"...hence I'm really only utilizing the 8051's P3.1 (TxD) and the Xbees Dout....". It should have read: "...hence I'm really only utilizing the 8051's P3.1 (TxD) and the Xbees Din....". To sum things up, as I said in my first post, TxD (P3.1) will be connected to the Xbee's Din and RxD(P3.0) will be connected to the Xbee's Dout. Sorry for the confusion. No sir the Xbee chips inputs I purchased aren't 5V tolerant (here's the link again: http://www.sparkfun.com/commerce/...ts_id=8664 ). I know that ideally I should have purchased two Xbee Pro-Xcc due to their native 5V tolerant inputs, but they where too expensive for my limited student budget. I have purchased 2 modules (+ 1 spare)802.15.4 (series 1), simply because they where cheaper and seem to suit me anyway with the additions I mentioned. ( Here is the datasheet: http://www.sparkfun.com/datasheet...asheet.pdf ). Thanks for your support, Kai |
