array size seems to be limited

Hello!
I need an array size of 96. Defining the array shows under variables only a maximum of 24 and the program is not working?
Any idea?

This is normal - only the first 25 array values are shown. If you need to view or alter the value of an array element above index 24, you can add a suitable expression - e.g. sensor_1_array[90] - to the watch window area of the Simulation Debugger when running the project via simulation or ICD.

The display only shows some (the first ...) but you should be able to use large arrays (Ive used 50000 elements) - assuming the device has sufficient RAM.
Can you post some code demonstrating the issue?

Hi Martin,
I found the program bug. array[24] have the address 0-23 ! I uses 1-24 and the program writes into a other variable.
The other info, that only 24 variables are shown is a point that is new for me.
Thanks to you
Jorg

Glad you've found the issue.
Some languages do use '1' based but this is much rarer - and loops to process the array would also tend to be '0' based (loop count 24 times using a variable .i - .i will take the value 0..23)

I have move this topic to a more appropriate section, as it is not a Flowcode bug.
