Hi, I need to perform a noise reduction and echo cancellation on an audio signal coming from an analog microphone and going out on a loudspeaker in order to make VOIP between 2 boards. I have an STM32F769I-DISCO board containing an STM32F769, a WM899...
Hello everyone,I am trying to connect the Quad-SPI Flash "SST26VF064B" to my MCU STM32H733ZGT6. I followed the tutorial provided by ST on YouTube (The Video calls "MOOC - External QSPI loader how to"). When I use the function HAL_OSPI_AutoPolling(), ...
Hi,I try to use your OV5640 board with your OV5640 driver in STM32H747 BSP in JPEG mode.The problem is that the FPS drop to 1 or 2 even at low resolution QVGA.Can you show me what registers needed to be modified to make it work correct since your dri...
We have designed, build and assemble a board with a STM32U575OGY6QTR. The first tests went well with the ST-LINK/V2 programmer connected to the board (driving the NRST). Now we have removed the programmer, and under some circumstances the MCU does no...
Hi,there are a lot of examples and tutorials available that describe how to use a FIR-filter (via function arm_fir_f32()). Unfortunately all these examples are either simple low-, high-, or bandpass-filters. Now what I'm looking for, is a possibility...
Hello Team,We are planning to use the MCU STM32L496QGI6 for one of our new projects.The MCU will be powered from a 1.8V source (since all external peripherals are working in 1.8V only).One of the SPI slaves is working in 3.3V, so we are planning to u...
I am working with the STM32F769 microcontroller and I can see that a lot of DMA buffers are placed in DTCM in the source code I'm working with. Looking at the data sheet ( https://www.st.com/resource/en/datasheet/stm32f765bi.pdf ) page 20 I don't see...
Can I measure low pulse duration(>10ns) using the STM32H Hrtim?Hi all,I'm new to STM32H7 development. So I'm hoping to get some help to start.I need to measure pulse duration in 5- nanoseconds resolution or less. I then need to transfer the measured ...
I am working with the STM32F769 microcontroller and very rarely I experience some strange issues with an SPI slave and I suspect it's related to congestion on the bus matrix (other, primarily DMA, transfers ongoing at the same time). Is it possible t...
Hello,I get an issue with the USB HOST configured on my STM32F2This USB HOST driver works well in my case, but it appears that the interrupt OTG_HS_IRQHandler is called too frequently (when I plug a device on the USB HOST post) and it's flooding my C...
