I need to have the four I2S inputs on the H7B0 device synchronised so that they all sample the ADCs at exactly the same time. One method is to run the I2S modules in slave mode and input an external FS and CK to all four I2S and to the ADCs, but it w...
There used to be a flowchart showing all the ways of programming the STM32H7 series through various ports including SPI, UART, etc, showing the order they are checked. But I can't seem to find it anymore. Can anybody point me at it please ?
Obviously Read Protection Level 2 is the most secure in protecting IP on the G series MCUs, but in the worst case scenario it could involve unsoldering and replacing the IC. Do you use Level 2 or is Level 1 secure enough for most scenarios ?
I need to divide a 24.576 MHz signal down to 12.288 MHz for a low power ADC so thought a timer would do this easily. But either I'm missing something or I have to put a value of 1 in the compare register and reload the counter all the time which see...
I'm using the latest CubeIDE to configure the H750 MCU. From the datasheet it says 96kHz sampling (at 32 bits in my case) needs a 67.6 MHz clock from the clock tree which I provide. However on the Pinout & Configuration page for the SPDIFRX modu...
Because I need SAI#1 to transmit the eight channels of processed data out into a multichannel mixing ring (4 channels per block). So SAI#2 will be the master on the ADC side and the three I2S interfaces slave to it.I agree it would be nice if they j...
> just look at SDI/SDO swap in slave mode vs master mode.Hadn't noticed that thanks. But datasheet must be wrong in one place or another55.9.2 :• SDO: Serial Data Output (mapped on the MOSI pin) to transmit the audio samples inmaster, and to receive...
