Manipulating array

 How did you figure out what the before and after is?

If he wants to transform a two-column array to a 8 column array, keeping the elements in memory order, all he needs is an array reshape. Am I missing something?

 

 try it!

And that's Altenbach for you.  Always finding the simplest and most efficient way to do something.

I didn't realize that the memory order was being kept.  Now that I see it, it makes complete sense.

Sorry, I ignored the "in a for loop" requirement. Sometimes I break the rules! 😄

I've been known to break the rules as well.  Usually for the better.  Besides, they are more like guidelines anyways.

In my test, this code does not work correctly, mostly because your array diagram constant in the upper left is 438x2. It needs to be an empty array! (In addition to the problem with "index array").

You also don't process the entire input array, but trim it after 50 columns, discarding more thant half of the data.

Here is a corrected version (LV 2010) as well as two alternatives discussed earlier. Let me know if you have any questions. I also placed some potentially useful green diagram comments.

 Register name                                                                                                      type              modbus location

FAULT	uint16_t	300004
TEMPA	uint8_t	None
TEMPB	uint8_t	None
TEMPA/TEMPB	uint16_t	300005

I'd like to search through an string array and if i find a uint8 variable I'd like to create a new row entry which is TEMPA/TEMPB   MSB,LSB uint16 like above.

Then continue the search. I have 300 variables in this string array and need to pull out all of the unit8 variables in this fashion and put them into uint16 for modbus registers transmission.

I dont need to append to the current array, creating a new array from the old one is preffered. 

I can then search through the final array and link the uint16s with modbus registers if  location != none 

How can i do this ? Any ideas?

James,

Your request has nothing to do with the old thread to which you appended your post, except the title.

Please start a new thread and reference this one. You will also get better answers if you show what you have tried and state what does not work about it.
