MDF and ADF: input data from RAM

Is it possible to use the awesome MDF and/or ADF on STM32U5 with input data from RAM? I have not found any configuration for BSMX for this. One use case is an high performance external delta-sigma-demodulator (ADC) on SPI with proprietary data format...

Resolved! How is SCLH and SCLL calculated in I2C_TIMINGR?

I have read the document RM0433 and AN4235, but the calculation is still a puzzle. For example, if my I2C frequency = 1MHz, I2C clock source frequency = 170MHz, AF=on, DF=off, rise time = 80ns, fail time = 10ns, how do you get the SCLH = 0x10 and SCL...

NUCLEO-H723ZG BOARD ADC NOISE

Hi, I am planning on using STM32H723ZGT6 chip on one of my boards. I got the NUCLEO-H723ZG to measure the 12-bit ADC noise. From the datasheet for STM32H723ZGT6, the max ADC noise should be 5 times the LSB or 4.02mV. (1 LSB = 3.3/4096) I am getting 2...
