Hi!I am experiencing some confusing behaviour on an STM32H743 series chip:I am running an injected ADC channel on ADC2, with trigger from the HRTIM. The HRTIM is triggering at 8000 Hz (200 MHz clock, prescaler div-2 and period = 12500). The ADC gener...
Hello We are working on a new project with STM32H723ZGT6. I want to control S70KL1283DPBHI020 DRAM with HYPERBUS communication using OSPI1. If you access 0X900000 memory to write and read data during the current operation, the data will not be read a...
Hello,In our application there is a STM32L073CZT3 component, we use timers and DMA to generate PWM that simulates a sine wave to start a motor.We encounter a problem with the microcontroller at high temperatures (about 80 degrees Celsius and above).T...
Hello. I'm having a problem with an STM32H503. I need to use the RTC, which is running on the internal 32kHz LSI clock. The clock configuration was created with CubeMX. When I check the RTC, I see that it has only advanced by 21 seconds in 60...
It's across 'U5, 'H5, 'H7 RMs, maybe more.How did I spot that? I was text-searching for 'NMI' ... :)JW
Hello ,I want to Access QSPI drivers in STM32H7A3VIH6. However in Cubemx there is only option of OCTOSPI1 and OCTASPI. My question is there way to use QSPI api directly like HAL_QSPI_Init instead of OSPi init?Or we have use OSPI only?Secondly i am us...
Same issue reported in 2020: https://community.st.com/t5/stm32-mcus-products/stm32g473-fdcan-pinout-contradicting/td-p/224770.As of DS12712 Rev 5, Table 13 Alternate Functions has PB10 and PB11 mis-labeled as FDCAN3_RX and FDCAN3_TX respectively.Unde...
Hello ST community,I am working on an application on STM32N6570-DK using the camera to detect humans with an AI model (X-CUBE-AI + NPU) and draw bounding boxes on the LCD using LTDC.I am facing a display corruption / glitch issue that only appears un...
In the FD_CAN register, there is a CEL[7:0]:, REC[6:0]: and TEC[7:0]:,The CEL register is not being reset on read and goes into the Bus-Off mode.Do I need to also reset the REC and TEC register?I am currently using the HAL_GetErrorCounter() function ...
Hello all,I have a custom board using an stm32h747bit6. I am able to flash it and it works exactly as intended, but if I power cycle it then it stops working? If I flash it and then reset the chip it still works fine.I tried some debugging, I config...
