Hi,I've successfully generated a sine wave using stm32 DAC. The current generated sine wave has the following properties; where min amplitude is 0 to max amplitude 4096 and the zero crossing is at 2048. I'd like to shift the output sine wave amplitud...

Hi STM32 guys/gals,The gray/white signal is for reference only, and that's the signal I'd like the generated yellow signal to achieve when starts and stops. I'm using DMA in circular mode to generate the yellow signal. However, I'm struggling to comm...

Hi Peter,Thanks for the insights. I came from the TI MSP430 uC, where the DAC supports both straight-binary and twos-complement data formats. In twos-complement data format, the range is shifted so that a DAC value of 0x0800 results in a zero output ...

Hi Mbrossett,Thanks for the reply. I temporary solved the problem by disabling the DMA at the end of the wave generation function. Then re-load the DMA counter with the new value to start the DMA counter again and that does the trick.
