Hello,I took over working code that I have for a DSP project from an STM32F439 to an STM32H743. On the F4 I had the external audio codec connected to the I2S peripheral but switched over to the SAI on the H7. Now I am experiencing excessive noise whe...
The CC1125 is a TI sub-GHz transceiver: https://www.ti.com/product/CC1125The User's Guide - https://www.ti.com/lit/pdf/swru295 - says that, after asserting CS, the SPI Master must wait for the CC1125 to pull MISO low before starting the transfer:I th...
Hello , I have a Nucleo H745ZI_Q board here Ethernet configuration and ping test done . Ping Test successfully ping's .Next i want send data from PC to Board or receive data How and where should i process(in code - function )the data and how sho...
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...
