i want to use pic microcontroller as high speed ADC and then i will sent the result

of conversion through TX in the pic ...so if we connect the TX of pic to

PC serial port to read the result of conversion...i do that because i do not have

FIFO memory to read from paralle port...so that .. what is the maximum

speed i can run the pic so i can read result from conversion
 

Re: PIC AS serial ADC

Hi
There are different speeds of the A2D based on the selected crystal. Maximum one is Fosc / 8 I think but you should review the data sheet. But this is not the only limitation. The speed of the transmission of the serial data may represent your end of dreams specially that you don't have a FIFO.

P.S. you can implement a FIFO using the PIC ram area and a small indirect read/write algorithm.

Thanks
Haytham
