Bash - Reading from file descriptor simultaneously

How to format a byte array to a 16bit CRC check for a Modbus frame?

QUESTION

Bash - Reading from file descriptor simultaneously

Asked 2022-Mar-06 at 00:30

I am working with Linux file descriptor at the moment to communicate with an external device via serial port, and I wonder if it is possible for me to duplicate the result returned the device.

In details, I used file descriptor number 5 to read and write to the serial port /dev/ttyACM0 in a raspbian device.

QUESTION

How to format a byte array to a 16bit CRC check for a Modbus frame?

Asked 2020-May-25 at 20:29

I am currently trying to use an Arduino UNO R3 as a master in a Modbus serial (not TCP/IP) communications protocol. I have attempted to use outdated libraries for this with no avail, mostly due to deprecated dependencies. Anyways I decided to start from scratch and my current goal is to write a value to register 301 (starting address 300) to a slave I.D. "5". Before connecting to my slave I want to make sure I can regenerate the CRC for the frame depending on whether I write a 0, 1, or 2 to the register. For writing a 1 I have the frame as "05 06 01 2D 00 01 D8 7B" and from my research I can tell that "D8 7B" is the 16-bit CRC for the data. However the problem is that I can't seem to replicate the CRC output on my Arduino. I believe it has to do with how I have prepared and formatted my byte array but I am not sure. I do not understand the CRC algorithms well which is why I am using a library, any help would be greatly appreciated.

The following code is a slight variation of the example sketch provided with vinmenn's Crc16 library.

As for replicating Modbus CRC16 with byte by byte method, according to the source, you need to use the parameters:

poly=0x8005
init=0xffff
refin=true
refout=true
xorout=0x0000
check=0x4b37

which means you should initialize crc as:
