Given the string (or any length string with an even-number of word pairs): "12345678"
How would I swap adjacent "words"?
The result I want is "34127856"
As well as, when that's done I need to swap the longs. The result I want is: "78563412"

-mtimeit -s'import swa' 'swa.withre(swa.s)' 78563412 78563412 10000 loops, best of 3: 42.2 usec per loop usec per loop
...and ....
I want to swap "byte pairs", not the order of the bytes.
Which is my original desired result.

Hello community. I have an interesting question today.

Then you can use a tool like "hexdump" to dump for an 8-bit stereo file each sample will be arranged as follows.
U for unsigned linear, and -1 for 1 byte per sample.

Q1. I am reading data from adc using serial communication with VISA, i am using baud rate of 38400Hz, with 12 bit adc and a total of 8 channels are confihured, so as per configuration, sample rate should be 800 s/s but i am getting 200-300 s/s, what could...

You check Bytes at Port once, outside the loop, immediately after initializing the port sample....
With 10 bits per character and assuming two bytes per, not sample rate.
Are groups of data separated, if at all?

Hi all,
How to format the number which can be converted to Byte[] (array);
I know how to convert the result value to byte[], but the problem is how to format the intermediate number.
This is by data,

I assume 100 bytes is too small and can slow down larger file transfers with all of the writes, but something like 1MB seems like it may be too much. Does anyone have any suggestions for an optimal chunk of bytes per write for sending data over a network...

TCP packets are subject to fragmentation, and while it would be nice are using TCP/IP over Ethernet, the maximum packet size is about 1500 bytes.
No, there is no universal optimal byte size.

I think elements, which leads to 8 bytes per array element.
