This is the UI desktop application aimed at creating tables with DAC digital values for embedded systems

1. Set resolution value. For example: 12 bit, then maximum digital value = 0xFFF
2. Set samples qty. Consider that the more samples the more ideal form you will get,but then you also have to use timer with higher frequency to get the same frequency of the signal:Signal freq = timer freq/samples
3. Set desired number of rows. Pay attention, that this is also the way to calculatevalues amount in the one row. So app only take integer values of (Samples/Rows) dividing result

• Setting:

• Table:

constuint16_tSin_12bit[10]={2047,3250,3994,3994,3250,2047,844,100,100,844};

• Waveform:

• Piecewise setting of the waveform with a demonstration on the chart

How it will work: the user has specified several points with x, y coordinates inside the period boundaries (0-360°).And the application will display the waveform on the chart. Then intermediate values between two adjacent points will be approximated.But this is just a theory. I know the application can determine the equation of a line between two points and calculate the value of any point on that line.This is too complicated a routine, so I'm looking for an easier way. If you know how to do this, I'm waiting for your response
