My STM32H747 (Portenta H7), with latest CubeHAL H7 drivers, fails on USB streaming, as USB audio from MCU to host (USB Digital Microphone).It enters in USB FS IRQ handler all the time the branch with the "Incomplete ISO OUT". Nothing comes out to PC....
Hi All I'm new to STM32 and I'm exploring it a little bit. I think I've found an issue in the HAL in configuration Line is referred to the external interrupt line to be connected. it is configured in the BSP with (void)HAL_EXTI_GetHandle(&hpb_e...
I think, using SAI for SPDIF Tx, can go wrong (in terms of clock config, the MCLKDIV setting):The CubeMX tool, used to configure SAI as SPDIF Tx, generates completely wrong PLL setting and codethe HAL driver, doing the config, in file "stm32xxx_hal_s...
Hi folks,I use MX to generate a code for STM32L4. I noticed, when I configure timer in one pulse mode, I cannot set OC CH1 in PWM mode with CubeMX. I could set it manually after code was generated, but it would be overwritten if I run MX one more tim...
NVIC_Type members are different for CMSIS 5.90 to CMSIS 6.0.0. Member IP renamed to IPR.STM32F1 SPL needs to be modified to be compatible with CMSIS 6.0.0.
Hi all, I am running into an issue related to writing backup registers on the STM32U535xx MCU. When I compile my code with -Oz, the write fails, whereas with -Os, it succeeds. The relevant C code is pretty straightforward:LL_PWR_EnableBkUpAccess();LL...
Hi ST Community members,I recently encountered a problem with the ISM43341-M4G-L44-SPI WiFi module mounted on the STM32H7BI3-DK development board. Here are the details of the issue:Context:I updated my Cube Programmer, CubeIDE, and stlink firmware.Wi...
I have a project which uses both OPAMPs. For both OA I use dedicated VINM pin.OPAMP1 works correctly.OPAMP2 behaves like the dedicated pin (M2 ball) is not connected to the input multiplexer.I 've tried - mode FOLLOWER: OK - mode STANDALONE, reconnec...
I want to send audio samples (received via SAI1 from PDM MIC) to SAI2_SD_B as SPDIF out.It does not work, because: the DMA does not seem to write the DR in SAI2:the memory is filled with audio samplesthe DMA seems to run (I get the HAL_SAI_TxCpltCall...
When using RTC, the GPIO pin state of PA4 may be corrupted. RM0454, section 23.3.3 says: "In addition, it is possible to output RTC_OUT2 on PA4 pin thanks to OUT2EN bit. Thisoutput is not available in VBAT mode. The different functions are mapped on ...
