Hi,
I'm writing a program that interfaces with a device on the serial port and in the documentation it says the folowing:
3.1.1. Header:Code.
The Header:Code combination is configured thus:
Header: 7 6 5 4 3 2 1 0
< Number of Dims> 1 F/A E/S
Where:
Number of Dims is a value between 0 and 22 identifying the number of dims to be transmitted (22 is equivalent to 100%)
Bit 2 is always set to '1' to ensure that the interface is able to maintain synchronization.
F/A defines whether the following byte is a function (1) or address (0).
E/S defines whether the following byte is an extended transmission (1) or a standard transmission (0).
Could someone please explain what "Number of Dims is a value between 0 and
22 identifying the number of dims to be transmitted (22 is equivalent to
100%)" means?
A link to the documentation:
