Hello,

I am using ask module of 433 Mhz.

I Have connected my ask transmitter data pin to max232.

and receiver data pin to my P3.0(RXD) pin.

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 to P3.0, which is working correct.

I have used lcd to display the character sent by uart

Thanks

I am designing pc controlled that means through UART.
Max232 is being used and ask transmitter is connected to it,which is used to send character using uart.
and ask receiver is used on the microcontroller side, it is connected to RX terminal of my controller..
still it is not working
