I spent this evening reading up on the two Easy Radio ER400TRS-02 Transceivers that arrived in the mail from England this week. Our plan is to use these in a networked toy to create a direct wireless link between two similar toys, or between one toy and a base station that can carry its signal over the Internet. The data sheet was full of good surprises. The transceivers are expected to run on +5.0 Volts and offer full Hardware Handshaking (CTS, RTS) functions which will allow for better control of communications with the buffer-less PIC microcontrollers. There is also a “Busy Output” and “Host Ready Input” pin (DTE, DTR) that will prevent lost messages in cases where either the transceiver or the microcontroller is powering up or coming out of sleep mode. Finally, the Easy Radios use very little power if they are not communicating, unlike the power-hungry WiPort, so there can be plenty of play time between battery changes.
