Hi I am using the USB CDC on a STM32L433 with the command MX_USB_DEVICE_Init(); to communicate through the USB. In my app, I go into standby mode (by using the HAL_PWR_EnterSTANDBYMode()) command. How do I disable the USB before entering standby? I ...
Hello,I've enabled a USB virtual com port on an STM32F373 successfully. The CDC_Receive_FS function in usbd_cdc_if.c gets called when data is received. I never expect to never receive a 'packet' greater than 64 bytes and have created my USB buffer[...
STM32F051C8T6产品，想用来和多摩川的编码器产品通讯，发送数据0x02，多摩川编码器发送6个字节返回。但用6个字节的中断得不到数据，用6个字节读取也无法得到数据。中断只能收到一个字节，02。有指导问题出在哪里了？
using stm32ide and a stm32f407 I would like to change the boot address to 0x8000000 to leave the first 4 sectors free from 0x4000 to position the boot at 0x8010000 I made a series of settings (not sufficient). in flash.ld file change1) FLASH (rx) : ...
Hello, by connecting an mcp2515 to Stm32, I enabled it to communicate properly with other cards via the Can network. However, when a message arrives, I couldn't understand how to receive it with the INT pin and I couldn't do it. I tried connecting th...

HelloFor future blower motors in our products, we are currently using the STSPIN32F0602. Unfortunately, memory space is very limited and we would like to use the STSPIN32G4 in order to introduce new products that are as future-proof as possible. Howe...
Hi all,For the last couple of weeks I've been trying to deal with receiving an ETH frame from PHY on my own PCB design with STM32H730VBT.To make sure the firmware is OK I took a Nucleo-H723ZI (CPU from the same family) and configured it to work with ...
I want to use two STM32F401xx MCU in proteus. One of them is to be a master and the other is to be a slave. This is my code for the master: #include <stdint.h> #include <stdio.h> uint8_t temp=0; void begin(); void end(void); void Write (uin...
Hello,I have been trying to make a driver for the Winbond(W25N01GV) NAND flash over QSPI but I've been failing so far. Can somebody give me some ideas about what I am doing wrong? #define UNPACK_UINT16_TO_2_BYTES(num) {(uint8_t) (((num) & 0x...
