I have instrumented my code as per the documentation: added dataacq.c and dataacq.h, called DumpTrace(). I do not receive any errors in STM32CubeMonitor however msg.payload.data contains only x values when I use snapshot mode. When I use direct mode ...

I am receiving 32bit samples from an external ADC via SPI (DMA) on the STM32U5 (NUCLEO board) at a rate of 51200 samples/sec. Does the ST-Link v3e provide an interface that should allow me to reliably stream these to my PC for further anlayis/validat...

I have a MEMS microphone (IM72D128V01, using this eval kit) with PDM output connected to a STM32U5 NUCLEO board.It's connected to the ADF/Audo Digital Filter peripheral which I have configured to provide a 5th order CIC filter with a 32x decimation f...

I'm working with a 24-bit external ADC (LTC2512-24) and stm32u5 (NUCLEO). With the MCU as master, after Data Ready Line (DRL) falling edge from the ADC I need to read 24bits via SPI within 740ns and then have SCK remain quiet until the next DRL falli...

By disabled you mean when I use direct mode instead of snapshot mode? Yes I get y values in direct mode

Turned out the issue was on the sensor side, the LR pin was accidentally floating and this controls dc bias

Ended up using the RDY method I described above and seems to work ok.
