Determining the max and min range of fxp type for fpga target with FIFO

[dream4me]

Used device : USB-7855R

To stream data from FPGA target to Host PC, I used FIFO.

At this time, the configuration option of the FIFO is like to as below

(1) Data type : fxp

(2) Singed

(3) Singed word length : 27 bit

(4) Integer word length : 13 bit

By using option, I obtained the value range of max = 4095 and min -4096.

However, when checking the value of FIFO in the Host PC, only +16 and -16 values are checked.

Why aren't more value being expressed?

This is not clear.  The two sides should be of the same data type.  Can you post code or a screen shot?

I'm sorry.

The wiring in my block diagram was complicated, 

so I made a mistake.

Thanks for your interest.
