Hi , as part of my project I need to decode Manchester encoded data and then convert it from serial to parallel.
Could you please help me on serial to parallel patt. How can I convert my data from serial to parallel?
Many tahnks

You are going to have to give some more information. Where is the serial data coming from? Where is the parallel data going? What hardware are you using?

It is a Telemetry Decoder. it takes Manchester coded data from a unit and then I need to convert it from serial to parallel and then provide the data to DAQ

How are you reading the Manchester coded data into LabVIEW? What data type are you using?
The convert from serial to parallel is still very ambiguous. Are you trying to say you are taking an array of booleans and changing them into array of bytes?
Are you outputting through an Analog Output? Digital Output? How fast do we have to put a value out?

The manchester coded data shall be read at 40kHz. The input data to the Telemetry is 0-5 volts digital waveform. I don't have the schematics but I think I will use serial port . The data out to DAQ should have time component so I think it should be analoge

The communication link from the chip to Telemetry is RS-485 so I think the inut data will be read using the serial port

You are talking about 3 different things.
1. An RS-485 serial port.
2. A parallel port.
3. DAQ
What DAQ device are you using? Is it NI brand? How does that interact with the data that is passing from serial port to parallel port?
