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...

Resolved! DBANK Option Byte default STM32G4

What is the default value of the DBANK bit in STM32G4 MCUs. According to the reference manual, flash memory address 0x1FFF 7800 has that option bit, and the ST production value is 0xFFEF F8AA, which would make DBANK default to 1. Does this mean STM32...
