hi
i have a data acquization HW in place, consisting of op-amps and filters.
What i would like to do now is pass this output to an ADC(successive approximation) which would output the 8 or 10 bits into a Parallel to serial shift register.
This shift register will then push out the bits serially and i intend to send these bits to a blue tooth module so tat it will send the data to PC or mobile phone eventually.
Question:
1. Is my above idea realistic?
2. Is it possible to achieve the above without any microController? Cause what i perceive here is that no microcontroller is needed as the ADC simply converts and pass it to shift register...Or is microcontroller needed to tell ADC when to sample, how fast to sample etc etc??
3. Is there a need for serial interface like Max-232?? Why is there a need for 232? can't i just use the shift register and send the bits to the bluetooth module?
I also understand that shift register requires clock to move the bits, and since my proposal is without a microcontroller, i was thinking of using clock generator to clock the register? Am sure there are such products in the market right? Or am i wrong to say so??
I really dun wanna use a microController cause its gg to add to the size and power consumption of my system, which is suppose to be portable.
Your comments on this matter please.
Thank you very much!
