I have a project where I'm using a Nucloe G474RE to produce a sine wave, all is working great; I have an array of 2500 values which produce a SINE wave starting at 0 degrees; I would like to add 2 further Sine waves starting 120 and 240 degrees later...

Hi All, I have a further query about the DAC output for this that is puzzling me, I have 3 sine waves all DAC conversions triggered correctly but I seem to have lost the bottom portion of the sine 1 and 2 ( these are on the same DAC) , it was work...

Thanks Michal,I have managed to sort it using DMA only , no software in main() at all.Its really simple .I have a 1 x array with 5000 values as the look up table covering 2 cycles (Thanks KnarfB)When you Start each DAC you add the number you want to...

You, of course, were correct; I needed 2 cycles of data in the array. I had to add an additional Dac channel for the 3rd phase output. I don't know the latency between the 2 DACs, but they are not in synchronisation unless I'm missing something, p...

Thanks KnarfB,The array is only holding values for one cycle and the max frequency is 60 Hz , thanks for the code snippet , it looks really simple to index into the array.if it's in circular mode, won't it loop around, or maybe it will try and contin...
