hello mahesh, the circuit is simple. so, i don't think you might have done any wrong connections. you only check the address bit of th Tx & Rx i.e. from A0 to...
Check if the ICs are working correctly.. this can be done by connecting Dout of HT640 to Din of HT648L with a wire and provide a common ground. remember to...
Thanks for your information. One more doubt.Can the address bits be left floating or it should be given 0 or 1? Regards Mahesh--- On Sun, 7/12/08, gautam kumar...
