    In order to use DAC in STM32L4 I have some problems to obtain a good converted signal with ramps between output samples which produce dirty output when amplified by any audio amplifier.
    Any suggestion about correct configuration?
    I have seen in your code a triangle amplitude of 2047 and enabled output buffer, I dont understand becouse a triangle parameter?
    Thanks in advance.

    Good code and reference. Get me started with STM32 firmware.
    Curious. Why mem to mem is not supported by DMA circular and double buffer modes? Under what condition to use circular and double buffer modes?
