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
Is your transmitter designed to work with RS232 levels?!
Is it even designed to connect direct to a UART?
What does any of this have to do with Keil?
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?!?!
