Hi,
I was wondering if anyone have tried interfacing their HAC-UM12 with an arduino board. For those who doesn’t know what an arduino board is, please visit this site: www.arduino.cc. A quick explanation on what an arduino do is it is a atmega 8 microcontroller which you can program to do, well, almost anything. Anyways, I am trying to make them communicate and it seems to be not working for me. I hope someone has an answer for my problem. Any help will be greatly appreciated. Thank you.
Jason
Arduino can be used for serial communications, so that should work perfectly fine…
Sparkfun does sell the Arduino boards too, even with an Atmega168 installed if I am correct (double program space compared to the Atmega8 that you mention). A Bluetooth Arduino is available too
Hey Jandirks, thanks for the reply. I guess I should be specific on what I was doing. I have two arduinos and two HAC-UM12. I uses the arduino’s 5 volts and ground to run the two wireless modem. The rxd/ttl (pin 3) of the modem is connectec to the tx (pin1) of the arduino. The txd/ttl (pin 4) of the modem is connected tot he rx (pin 0 of the arduino). The rest of the modem pin was left unconnected. Now I tried to send a simple program to send and listen on the serial port. I know the program works because I tried to run it withouth the HAC-UM12 and they see each other’s transmission. I can post the program if requested. I did some test as well to know what is going on each pin of the HAC-UM12. I noticed that both txd (pin 4 and pin 6) have a constant 5 volts on it. I am not sure if that is normal. Any suggestions will be greatly appreciated.
