Directly Connect an RF Transmitter to the Computer?

jsmasterking

So I have a simple single-channel RF transmitter and I installed a matching receiver on the boe-bot. Is there a way I can directly connect the transmitter to the PC w/o using another Stamp?

I know the BS2 has 4 pins dedicated for serial communication, so could I just attach the transmitter to the data transmit pin on the serial port and the receiver to the SIN pin of the bs2 and just use the serial port? And also what is the function of the ATN pin on the bs2? Flow control. There are also two serial pins shorted across on the BOE, why?

Also I believe the TX & RX use TTL logic so anyone see any potential voltage problems?

You will have to contend with voltage and polarity. Best way is to use a chip like the max232

You can't directly connect the RF transmitter to your PC... you also don't need to use an expensive BS2... this is a great job for a BS1... you could also use a max232 circuit (like this one from Pololu, http://www.pololu.com/products/pololu/0126/ ... there are many, many others like this out in the market). You could even use an PICAXE 08M, which is only $3.
