No problem.
I can follow the document just fine.
I have simplified flowchart and cheated a bit.

LUT values on 8 bit chips are only 8 bit wide
Therefore only numbers 0 to 255 can be used.
On the over voltage side you wanted 260,265,270,275 & 280
So what I did was subtract 50 from each number, then ...

So SW_ST1 & SW_ST1 will have a value e.g 10, so you want to retrieve the 10th number within the look-up table?

One thing I have noticed is you have a calculation like this: SW_ST1 = (SW_A * 4) + (SW_B * 2) + (SW_C)
You will have errors if SW_A, SW_B or SW_C are Bool.
You will need to change Bool ...

Hi vonskyes,
If you post what you have done so far, then I will have a look at you Flowchart, and let you know where your going wrong.

hi guys,
Thanks for all your tips and LUTs they have been helpful. But somehow i am still having problem with mine and i need you thoughts on this. I am relatively new to flowcode, started a few months back so i don't know my way around much.
i have a table where i am comparing two values
switch ...

Hi Jorden,

There is one thing vital to remember when it comes to look-up tables

If you have 58 sets of numbers, then your result before retrieving LUT must never exceed LUT Quantaty -1
i.e. 58-1 = 57


E.g. If you have several sets of numbers assigned to variable called lut_data:

rom char* lut ...

I thought I would put together a basic tutorial on Look-up tables.
I have Benj to thanks as I first read about LUT here:

I thought I would try and write a tutorial form a different perspective.

Thanks werner for spotting my ...
