I am using STM32H5 nucleo board and it is connected with MIC which gives PDM output based on analog input. I am reading the mic data using I2S protocol. To verify the received I2S PDM data, I am giving this data directly to DAC to get original signal...

I am trying to use second half of OCTOSPI pins in single memory mode by setting MSEL bit for QUAD SPI communication with Flash memory. Even though i set the MSEL bit to send the data through 7 to 4 pins, still data is going through the 3 to 0 pin onl...

I am using NUCLEO-H563ZI evaluation board and i want to create external flash loader for IS25LP128 QSPI flash memory. I used external loader files from GIT HUB and .stldr file in STCUBE programmer external loader folder location. when i try to read f...

Thanks for your information. I just want to know one more information like how the memory mapped mode is used. I want both flash and RAM memories should be considered as internal memory. Is it having two different addresses for memory mapping?

Our real purpose of external ram and flash is if we dont have enough space from internal ram or flash, we will have to extend some part of code storage to flash similarly data for ram using linker script. We dont think this solution will work out for...

@KDJEM.1 @Tesla DeLorean I am able to switch the NCS functionality to other pins from PE11(NCS1) to PB10(NCS2) with manual coding but even though i choose ioselect as 0 to 3 or 4 to 7, the data is reflecting in other half. I chose single memory confi...

I am not clear how its working now after changing the pin frequency configuration from Very high to Low. I changed like below and its started working.GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;I configured OCTOSPI clock as a 1MHz. Is it really consi...

Are you able to send data through the 3 to 0 pins only?Yes, Even though i chose IOSELECT 7 to 4 pins, data is going through the 3 to 0 pins. Is the MSEL bit set correctly in debug?This is the only place i am selecting the 7 to 4 pins.sCommand.IOSelec...
