HI STM Team,I am new to STM32 Board. I am using NUCLEO-F439ZI Board. When I was connecting my USB-OTG side to my PC, I will suffer from the "Unknow USB Device" Error, The error screenshot was attached below for your reference . Please Guide me to rec...
Hi, I am trying to do an application where I am using 2 PDM output digital MEMS microphones to get a stereo sound from them and then play it. My question is when I select I2S as Full-Duplex Master for STM32F407VG it only has 1 SD pin. Should connect ...
Dear all,I've been wrestling with a communication glitch that's been causing me some serious headaches. Here's the lowdown: I've got this control board hooked up to a pump, and I've been trying to send commands to it via USART1 on my own STM32H735G-D...
Sorry, I have another question to ask everyone. I'm currently using the Nucleo F429ZI with SPI interface to receive 12-bit encoded data from another ADC. The Vdrive of that ADC can provide 3.3V or 5V for driving. However, the high level of the STM32F...
Hello Guys,I am new to STM and USB HS but have some experience with PICs and other AVRs. I've designed my own custom board (for a keyboard). So after I generated the USB HID code with STM32cube IDE, I successfully downloaded it to the STM, however, n...
Not a question: just to share with you my experience and "tricks" to connect a QSPI PSRAM on STM32U5A5/STM32U575 and potentially other MCUs (from a FW point of view, not HW).BackgroundI want to extend my own PCB, STM32U5A5 (LQFP64) with an external R...
Hi all, I'm working on the NOR Flash via OSPI(using as QSPI) with the STM32U585 board. implementing this via filex and levelx, i have done all the configuration referring to the example provided by ST with the minor changes. I'm getting error in the ...
This morning I got an email from ST which included a section on using VS Code to target STM32 CubeMX projects.This appeals to me since the STM32CubeIDE is seriously lacking in focus from ST. It has looooooong standing bugs which no-one cares about, b...
Hello,I need very simple communication of my STM32F722RET6 via USB (Full Speed) - I need to send every 10 ms only data of 20 bytes to some program made by C# in Visual Studio. I found some samples of USB communication on GitHub but I was not able to ...
Hi,I have timer with period 1 sec (80 MHz clock): htim2.Init.Prescaler = 80-1; htim2.Init.CounterMode = TIM_COUNTERMODE_UP; htim2.Init.Period = 1000000-1; Global var (volatile uint32_t) increased every time counter wraps around void HAL_TIM_PeriodE...
