Hi, go to see this site WEB, www.radiotronix.com Is the full duplex module communication Regard Denis ----- Original Message ----- From: "Lars v.d. Doelen" To: Sent: Tuesday, February 05, 2002 10:11 AM Subject: [EE]: RS232 Communication via RF link Dear electronicers, The recent "low power rf application" thread got me exited about building my own rf link between my computer and my PIC controlled robot. Unfortunatly the thread got useless after about 2 reactions, so I still didn't get the answers I was hoping for. I'm trying to build a bi-directional, wireless link with my pic (16F84) robot. I found several commercial TX/RX modules that only go 1-way, but I would like (if possible) to build my own TX/RX modules that will give me 2-way communication capabilities. My main reason for this is a limited budget. The above project leaves me the following questions: * Can anybody help me to a 2-way TX/RX schematic that will allow me to send/receive bytes to/from my PIC? * What kind of trouble am I getting myself into by trying to build the rf modules myself? Is saving a few bucks worth the hassel? Thanks for any response you'r willing to give me.
