Converting signed INT32 to 32bits Hex format:
If you want to convert an INT32 value to a Hex formatted number to place in the DATA part of a
packet to send to SOLO, based on the sign of the data you want to send, you will face the
following two conditions for the conversion:
Condition1) If the data is positive:
If the number you want to send is positive, the only thing you need to do is converting the
integer into HEX like an unsigned value
Condition1) If the data is Negative:
For sending negative Integers with Hex format to SOLO, you need to follow the following steps:
1. Subtract the absolute value of your number from 4294967295(Decimal) or
0xFFFFFFFF(Hex)
2. Add 1 to the result of step 1
3. Convert the result of 2nd step to Hex
Example 1_ positive Numbers:
Data to be sent: 1536
- Hex (1536) = 0x00000600
Example 2_ negative Numbers:
Data to be sent: -56329
- Hex (4294967295 - Abs (-56329) + 1 ) = 0xFFFF23F7
