Hi all,
We know that after ADC conversion, we will get pulse code modulation (PCM). For my ADC,there will be 10 bit resolution. The output is 10 bits parallely. I want to transfer this output data over bluetooth device. My question is do I have to convert these bits to serial so that I can pack these bits and send them? Could you please help me with this? If I have to convert, what method or chip do I have to use? Thank you all!

How does it follow that -

We know that after ADC conversion, we will get pulse code modulation (PCM)

- I do not see why this is so.

Your second part is hard to answer. Bits (binary digits) are discrete entities. If you load the 10 bits of your conversion into a register, then they are in the form of a partial word. Shifting the register right by one bit and transmitting each successive bit effectively does a parallel to serial conversion.

You can't pack serial bits. Read up on your bluetooth interface and you will see how to send data.

 

Sorry for any misleading. Lets repeat it. I have PIC18F4550, and use this MCU do ADC conversion. I have bluetooth device(eb301 from www.a7eng.com) that will connect to this PIC via RS232. My question is that will the ADC converted data directly transfer to the bluetooth or I have to manipulate any other steps before the data can be transfered to bluetooth device pin? Thank you

 

You need to read and understand the internal process for the A to D converter and the data it produces.. If the PIC has the RS-232 interface built in, then that will handle the parallel to serial process. If not, then an IC like the MAX232 will handle it.
