The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello,I'm facing a strange issue with the quadspi peripheral.I'm using it to interface with a W25q256jveiq, a quad spi enabled flash chip from Winbond.As long as I use one line SPI or dual I/O mode all works fine.I can access the flash chip with no i...
Hello,I have an STM32F373 and have successfully enabled a USB virtual com port.I currently send data packets from a PC host to the slave device and include a 'deviceId' in the packet data header.I would like to support the single PC host communicati...
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....
I am currently ramping up a new project which has a HyperRAM installed (S70KL1282 - like in the example project of STM32H735G). With the help of this sample project code I can successfully write and read with memory mapped mode from the 16 MB RAM - b...
Hi All,Today I received two NUCLEO-H503RB boards, but when trying to get the ADC calibration values the processor HardFaults. According to the datasheet it's the correct address: Also when trying to access it with the debugger it failsAlso the temper...
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...
