Can anyone tell me where to find info on coupling transmitter/receiver to microcontrollers?
Hi Spasm,Spasm said:Thank you masta Chippie for the info..Yeah..thats actually what i wanted to do..data transmission.
But Chippie..does the Tx/Rx u had mentioned has a DAC/ADC converter all build in? How bout for other Tx/Rx? Can I just put the output digital signal straight into the input for the Tx??
By the way do you know anyone that had already done a similar project like this?
I can't seem to find any...
I'm not familiar with the 68hc11 series (I major on the ST62 series) so Ive just looked up the data sheet. I see the 69hc11e** chips have 512K of RAM. Remember that 1 character in your text message will use 1 byte. Depending on your program you may need up to 30 registers for timer data, flags etc., so think of probably 480 characters for your messages. The max characters will depend on whether you intend to hold the entire message in memory before transmitting it.Spasm said:Hi pebe.
Thanx for the info on transmitting the data. I'm still gathering more information about which type of Tx/Rx to use.
Btw.. For transferring data between micro..lets say text msgs..is the 68hc11 with 512 bytes memory enough for this operation? I've tried searching at motorola sites but cant seem to decide on which microP to use..any suggestions?

pebe..ohh...okay...thanx for the info..btw..how many times do u think the program should retransmit before the receiver side gets the data?
