Hi all,we are developing a board based on STM32F429 chip.In particular I'm developing a composite USB device on USB OTG port, showing a custom device + a CDC device [ep 0x85, 0x06, 0x83] using USB_Device_Library code.Windows correctly shows 3 items: ...
I would like to use the WKUP 6 (RTC_WUT_S) to wake up from Standby mode. I am already using WKUP 7 with a pin so I need the RTC to be in safe mode.What would be the best way?
During simple task I need to measure Vrefint and Vbat, so, I open CubeMX and configure ADC to read Vrefint and VbatThan I setup a DMA to read values...I write a really simple program:/* USER CODE BEGIN PD */ #define ADC_BUF_SIZE 20 /* USER CODE END P...
HiOn STM32L4xx Ref Man Programmable voltage detector (PVD) supports external input PVD_IN.How to configure the GPIO for PVD_IN (ex STM32L4 PB7)?How to configure VREFINT?Is there any example?
Hello, I'm trying to debug an issue I'm having with the GPDMA on an STMu5. I believe I'm mostly there but for some reasons I'm missing only some DMA triggers. So the situation is as follows: I'm trying to read the IDR register of a GPIO port into mem...
Dear Team, We have selected STM32H733VGT6 (LQFP100) for our Project and trying to configure and design an ETHERNET (MII Mode) interface.While configuring it using CUBEMX,1) ETH_TXD2 is showing up on PC2_C Pin (No Alternative Pins Available).2)ETH_TX_...
Hello,I am wondering/unsure about the XSPIM in H/RS MCUs.I want to connect a quad-SPI NOR flash to an XSPI. Is the XSPIM needed at all?Let's say the XSPIM is in default configuration, i.e. EN bit in XSPIM_CR is 0.Does that mean that I can configure t...
Hello everyone,I am looking for middleware to control NAND flash using the STM32U535CE.The target device is the Macronix MX35LF4G24AD.I would like to perform page program/read, bad block management, and 8-bit ECC processing per 524 bytes. However, I ...
Hi all.I'm working on STM32F427VI + Hal Library generated by CubeMX6.2. I use DMA and set the clock frequency of the SDMMC controller to 24MHz.If an SD error occurs through the run of the program, I remount SD Card by the following functions: 1 - MX_...
in the ili9341.c file located in the "stm32cube_FW_F4_Vxx/drivers/BSP/Components/ili9341.c" in this file there is a function called LCD_IO_Init(); what file is this function at i noticed that in the ili9341.h file the function prototype for LCD_IO_I...
