Hello, Friends, I am using ADC(16 bit) to measure the STM32H747 Internal Temperature and VrefInt based on external reference voltage (VDDA 3.3V, Vref+ 2.5V). The VrefInt result is 1.221V, which looks good. However, the temperature result is 150C, whi...
Hello,I acquired the STM32H750B-DK development board. Initially, when I connected it to my PC, it would power on with a display and interface. However, for the past month, it no longer turns on at all. When I connect it to my PC, a folder opens with ...
Hello, I'm new to STM32, I bought a Nucleo board with a STM32F334R8T6I want to generate a PWM of 10kHz and read some data in ADC channel, unfortunetely, there some conflicts between this two and I can not generate a PWM with more than 5kHz.I need som...
I am currently working on a H723 based HS USB device with external USB PHY (USB3320,USB3340,USB3300 tested).While testing i have noticed that seemingly randomly between debug/flash cycles HS USB stops working with usually no activity on the bus but t...
Hello,I'm looking for some troubleshooting advice. I saw a few tickets regarding this kind of problem and confirmed that __HAL_RCC_PWR_CLK_ENABLE() is called before setting the initial voltage scaling. This test code is completely auto-generated from...
I have recently purchased an STM32H753ZI board and want to configure the differential ADC to read signals directly from a function generator. I have configured it based on the following setup, but I am facing several issues with the output.Issue 1: I...
Hi there, I am writing a custom video decoding app that process custom stream JPEG frames from USB, without any standard on a STM32H747.So far, (more or less) so good, I use CM4 for USB operations, and CM7 for JPEG decoding and DMA2D pixel conversion...
I couldn't understand the pinout of the nucleo boardHere in CN8 the blue side pins is mentioned with both D43 and PC8. same in CN7 pin number 1 is mentioned with both PC6 and D16. But which of pin is actually connected to this specific header.
Hi, I'm developing a STM32H750VBT6 board that need SDRAM, the datasheet said that only LQFP144 package does not support SDRAM, but I cannot find SDRAM option in FMC configuration. Can someone please help me.
Hello Friends,I use STM32F373 for 16-bit SADC.I have single-ended input 0V to 3.3V. VREFSD+=3.3V and VREFSD- =0VWhen input Voltage change from 0V to 3.3V I get values 0 to 32767. Is it not possible to get 16-bit (65535) data?Always signed?my configur...
