I am using CubeMxIDE v1.0.2 with STM32f031F6Tring to read internal batt and temperature. But can not successfull.. I found that SMT32F031x6.h library file and corrected the following lines#define ADC_CCR_VREFEN_Pos       (22U)                        ...

Rant: Why do G4 headers still use uint32_t in #define?

Hello,I have reported several time about the miss-use of uint32_t in #define. With G4, STM coders had the chance to get things right from the start. However they did not use the chance. Must every device group at STM make its own errors and does not...

SPI not working with STM32L4R5ZI, unable to find RCC_PERIPHCLK_SPI1 for enabling SPI1.

There is no peripheral clock available in specific for SPI in stm32l4xx_hal_rcc_ex.h, Could some one help which clock needs to be enabled for SPI1 communication​ 

USB_OTG_FS registers similar to USB_OTG_HS ?

hi, I want to use USB-FS. For initialisation I used the tool integrated in the cube IDE. The RM contains the HS-registers but not the FS-registers. Since the tool changes bits that are not supposed to be changed (namely: GOTGCTL) I assume the registe...

in STM32F446Ve，use STM32Cube General code，nitialize fmpi2c to slave mode, OA1 = 0x29, oa2 = 0x21, nomack = 0x07, interrupt enable, master MCU sends data to bus, but fmpi2c cannot generate interrupt，why？
