I could not find yet a specific information regarding IDAU configuration of H5. Is it same as U5 as described in AN5347 ?Edit: I think it is the one in the reference manual (RM0481), I realized colors (Figure 2) indicate the IDAU mapping.
Hi everyone,I have a hardware problem with STM32G474RE on startup. If I try to supply this MCU directly from the lab power supply, it runs correctly, but when I have dips or drops or fast switching on the supply, I notice that the MCU doesn't start. ...
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 ...
