Re: Look-Up Tables Tutorial

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 Boo...

Re: Little Help with Lookup Table

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_data =...
