I have configured the readout of 4 PDM microphones through the SAI interface. I am using 1 slot of 32 bits per frame. I have enabled DMA.Unfortunately, when reading PDM data, the first 6 and last 2 values of the array are filled with zeros. This happ...
Hi,I am working on SPI bus communication between IMX6dl MPU and STM32L476 MCU.MPU work as a master device and MCU work as a slave device.Configuration of MPU is:pinctrl_ecspi3: ecspi3grp { fsl,pins = < MX6QDL_PAD_D...

Hello everyone, I'm trying to develop a simple DAQ, most of the code is generated by stm32cubemx then I just added two callback (HAL_ADC_ConvHalfCpltCallback and HAL_ADC_ConvCpltCallback) to send the half buffer data by the USB virtual com, pretty s...
I want to be able to program a STM32H7 device with something like a device ID, for example, this device is #10, and that devices is #55. This would affect the behavior of the device, so it must be possible to read that number through the firmware, so...
Hello Community!,I am working on STM32F745IG, where i am interfacing 24 SPI slaves to STM32F745IG MCU. Please let me know how many slaves can be connected to single SPI interface in STM32F745IG?. I looked into datasheet, I couldn't able to find. Than...
Hi, I have STM32F407VET6 which has such memory layout.As I understand CCM data RAM is unused by default and just waits to be used? So can I move STACK and HEAP to it? How do I move it? (I did not find defined STACK address anywhere in KEIL project)Is...
Hi, We are developing a baseboard for the NUCLEO-F767ZI and use the ZIO connectors. Right beneath CN9, CN8, CN10 and CN7, there are mounting holes , that we want to use to make a robust mounting for industrial use. But the holes are very near and nor...
This MCU is having 3 RAM sections: RAM : 640KB,RAM2: 64KB,RAM3: 384KBI have modified my linker script(attached here) but don't know why the framebuffer is stored in RAM as well RAM3 section as per below snap? Linker script: STM32L4R9AIIX_FLASH.zipFol...
Hello,i am having problems to read data from the QSPI nor-flash if the address changes from 0x90FFFFFF to 0x91000000Everything is fine from 0x90000000 to 0x90FFFFFF but beginning from 0x91000000 there is no data.Example, i have an array stored at the...
