Referencing a ROM table in a C block

[Brendan]

First, a happy and prosperous new year to you all

Hopefully a quick question...

Having declared a 16 x 16-bit ROM look-up table using the usual LUT component, I'm trying to establish the appropriate way to reference values in a C block? e.g... FCV_THISUINT = FCV_THISTABLE[indexval] is clearly incorrect.

Many thanks,
Brendan

Hi Brendan,

The easiest way to check this is to define some code that does it and then look at the C generated..

For example in a calculation I do :

Code: Select all

.x = lut1::GetInt(2)

This 'expands to' (using customize C code or view C)

Code: Select all

FCL_X = FCD_00fb1_lut1__INTLIST(2);
