please help.


i need to know how to convert the tx/rx of serial port to binary like to 8 pins of 5v logic...

 

It's already binary - do you mean you want to convert it to 8 bit parallel?.

Easiest way is to use a PIC, but you could use an old hardware UART? - but that's a big chip and requires a lot more support components.

He might also need ascii->binary conversion too. I agree, a PIC would be best.

 

A shift register and a state machine should do the job. You could use an FPGA or a couple of PALS.

thnx for the reply...

i want to have simple schematic diagram of the device... that converts 1 pin tx to 8 pin logic

Maybe use an old chip like this one:

But as stated above, something like a PIC (16F628, etc) would be easier to use and more modern.
