Hello,
I am using ask module of 433 Mhz.
I Have connected my ask transmitter data pin to max232 as i am sending the data through UART.
and receiver data pin to my P3.0(RXD) pin of 89c51.
But it is not working fine.
The code is correct because i checked it using wired connection that means directly connecting max232 pin no.12(tx pin) to P3.0, which is working correct.
I have used lcd to display the character sent by uart. What to do to make it work wirelessly using uart
Thanks
Very, very strange that you in one direction needs a MAX-232 and in the other direction doesn't.
Actually i send my signals from the hyperterminal of my pc. So i need max232 on one side, and i have connected it to ask transmitter. and at the other end i have connected ask receiver to rxd pin of my controller. I am not sure whether my module supports directly uart signal..
Well, don't you think that's a pretty fundamental thing that you really need to know before trying to use it that way?!?!
