DLP3030-Q1: Read and Verifying VLED Current and Voltage from TMS320F2803x Piccolo SPI and DLPC120 SPI interface

Part Number: DLP3030-Q1

Hi, I am trying to implement the read SPI command for VLED voltage and current (C5h) from TMS320F Piccolo and DLPC120. I am getting 4+4 byte Raw data (Voltage and Current). 

I used the float conversion as mentioned in "DLPCU061_piccolo_SW_Guide_2018", But I could not read any proper voltage or current value. I could not see any variation in voltage or current even, If I change the input supply or changing the brightness.

Also I need to know, how can I measure the actual measurements and compare with the obtained raw value. our aim is to  read the over voltage and over current please suggest if there is any other method to read.
