Hi,
I want to use my F072's DACs to output a sin and cos signal. to save on memory I want to have only one buffer holding the values of a SIN function, COS values should be taken from the same buffer. Basically, I need the DMA for channel 1 to start from the beginning of the buffer and for channel 2 to start at an offset. Of course, I can't just do something like
HAL_DAC_Start_DMA(&hdac1, DAC_CHANNEL_1, lut, no_samples, DAC_ALIGN_12B_R);
HAL_DAC_Start_DMA(&hdac1, DAC_CHANNEL_2, lut + no_amples / 4, no_samples, DAC_ALIGN_12B_R);
because that would make the dma access elements outside the buffer.
in the reference manual I found the register DMA_CNDTRx register, is this the way to go?
