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...
早上好！ 在装机生产中STM32F103RCT6芯片能正常工作，成品机器交付客户使用后出现STM32F103RCT6芯片烧毁损坏的情况。成品机器与客户端通讯接口内信号线是直接连接芯片I/O口，客户端与成品机器联合使用，当成品机器出线异常（后排查为STM32F103RCT6芯片烧毁），客户端未出现芯片烧毁的情况。相关直连引脚为【PB3】&【PB4】，PB3做输出I/O量，PB4做输入I/O量。 请问该芯片烧毁的原因可能是哪些？
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 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...
