Hi,

This is a data packets obtained from DLP NIR through UART using RaspPi as follows:

How to do the next deserialization? How to decode the data or write the C++ struct for the data packet?

For example, I only can identify this data structure (which i'm not sure if i do it right, but struggling with the rest.)

struct {

unsigned char [4] magicid;

int intlsize;

unsigned char [128];

}

Hello User,

What commands are you performing to receive this data?

0 Hirak Biswas over 5 years ago

TI__Genius 10925 points

Hi User,

Kindly confirm if you are using NIRScan Nano EVM or the NIRScan EVM

0 MiaaTn over 5 years ago in reply to Philippe Dollo

NNO_CMD_FILE_GET_DATA

Hi, sorry. I'm using NIRScan Nano EVM.

0 Philippe Dollo over 5 years ago in reply to MiaaTn

TI__Mastermind 28005 points

Thanks for confirming.

It looks like this command has a variable return size depending on the requested data. What are you requesting?

Regards,

Philippe Dollo

Hi MiaaTn,

Kindly see the NIRScan Nano user guide for detailed instructions on how to parse the UART packets command and reply packets. You can also refer to the NIRScan Nano GUI source code, which implements the UART Command parsing.

Thanks & Regards,

Hirak.

I use these commands:

NNO_CMD_SCAN_SET_ACT_CFG

NNO_CMD_PERFORM_SCAN

NNO_CMD_FILE_GET_DATA

.............

Basically, the NNO_CMD_FILE_GET_DATA supposed to write the data from the scanned data NNO_CMD_PERFORM_SCAN, right?

But, the result are in the bin data packet... I don't know which represent which.. or are they any function to deserialize/decode the following packets?

Hi MiaaTn,

Our DLP Spectrum Library provides functions to deserialize the incoming scan data files. To understand the usage of this library for decoding the scan data kindly see the NIRScan Nano GUI source code, which implements and uses this functionality.
