Creating Arrays in ESME HVAC

[POPE3909]

Hi Guys,

I'm stuck while trying to create an Array with its size (Upper bound) being a EEPROM variable instead of a set constant value.

Here, Num_Units is an EEPROM variable which is also UINT. When I compile it, I got the following error.

If I replace the Num_Units with its value (eg: 10), it complies successfully and creates an array of size 11 (0-10). I tried declaring inside the ST program like the following, but the program does not allow me to do so:

How can I achieve this please? Any advice would be greatly appreciated. Thanks.

Hi,

this is not supported, the size of an array has to be based on a constant value or a constant variable, because the space is allocated at compilation time.

You have to define the array with a size equal to the maximum value that can be assumed by your EEprom parameter and use just part of it when the EEprom value is lower than maximum.
