I ported an application from STM32L496RG to L4Q5. Most of application is working except the ADC acquisition because of DMA and the new DMAMUX1. I used the LL ST library unfortunately I didn't find any LL example of ADC + DMAMUX. Could you give examples?

ADC in dual mode with sampling frequency of 10.66 MS/s (5.33 per ADC).The System clock is set to 120 MHzThe ADC clock is set to 80MHzThe ADC1 IN8 ext3 is trigged by TIM2 CC2.The ADC data transfet is done though DMA2 CH3

I have the STM32446e board. I've been trying to get any sort of analog mic input working through the onboard WM8994 codec. None of the provided examples support this. Hardware background, so I'm confused by all the drivers. Any easy way to do this?

The examples only support the digital MEMS microphones on the board. I'm uncertain whether the BSP actually supports using analog in. The wm8994.c driver supports analog in, but I'm not certain this function is actually being called by the higher abs...
