Hello,I would like to design a microphone array with up to 16 microphones. I want to use the stm32h7a3zi board which has a lot of peripherals.I was looking at the DFSDM interface, but with only 8 channels / 8 filters up to 8 pdm microphones can be ha...
Hello,Im working on a program which sends data from the ADC to the computer. My problem is that the data from my STM32H563ZIT6 is bad. I first noticed this from looking at the data sent from the computer and confirmed this by outputting the ADC data ...
I found an application note which goes in depth on DMA transfer speeds and clocking for F7 chips, but haven't been able to find anything similar for H7 chips. I have a few questions:How are each of the DMA controllers clocked on an H7xx chip? My assu...
Hello, We use STM32H755 with a 25MHz crystal oscillator connected to OSC32_IN and OSC32_OUT OSC_IN and OSC_OUT pins. Probed on the bench, I see a sine wave with a DC offset and low amplitude. Can you comment if the attached waveform looks okay? My ex...
Hi,I´ve a application (with RTOS) where I do a FW update via the internal UART bootloader (BOOT0 pin method).After flashing is finished I set the Boot0 to GND and toggle the reset pin. The application starts, but I don´t get USART interrupts any more...
Dear Community, i got two interconnected questions, as i want to build a measurement system that measures and generates sine signals and multi-sine signals with frequencies of up to 1 MHz. For this task i would like to have 10MSPS DAC and ADC acquisi...
LTDC prevents CPU (of my MCU) from going into sleep mode. When i deactivate the LTDC clock, the CPU goes to sleep mode. LTDC interrupt is enabled trough IOC, without enabling of LTDC interrupt, screen remains black. I use the following MCU: STM32L4P5...
Hi,We have a customized board with STM32F103, it measures water level and sends the data to a server, and then enters into Standby mode for 1 minute after setting up a RTC alarm for wakeup. Occasionally, we see wakeup failures. This happens randomly,...
Hi I am working on a project with STM32H730IBK6Q and STM32Cube IDE 1.16I am trying to use PA0_C as a GPIO, but the GPIO function is not connecting properly. PA0 is used an ADC, not as a GPIO, so from how I understand muxing there should be no conflic...
Hi ST Community, I’m working on a secure boot implementation for the STM32U3 series and need to replace the factory ROM bootloader with my custom secure bootloader. Here’s what I’d like to clarify: Can We Fully Remove the Factory Bootloader?The STM32...
