Clock tree frequency values duplication in code

Hello,It seems that most examples (stm32cubeh7) are independent in clock tree values, which is exactly the correct way to do it, yet some of the examples are using hardcoded values duplicated from clock tree (duplication) which seems like a bad idea ...

HAL_RCCEx_GetPeriphCLKFreq supports only SAI and SPI ?

Hello,Is there any reason why only small part of peripherals is supported in HAL function HAL_RCCEx_GetPeriphCLKFreq , ( SAI and SPI ) ? What about all other peripherals ?/** * @brief Return the peripheral clock frequency for a given peripheral(SA...

I would like to create a USB Host using a STM32F437IIT6, I am using STM32CubeMX version 4.1.0.0 but there is no choice for a USBTMC class host. Is it possible to use the existing libraries installed to implement a USBTMC Host. Thank You, William Leippe

identifier"I2C handler TypeDef" is undefined.

I am merging two projects .One project is wrote in stm32f401RE and another one is stm32f429i-discovery board.I have already included all path and build the project.It shows error like identifier is undefined.only one file path is not included.But i g...

In some cases HAL_UART_DeInit is used before using HAL_UART_Init, why is that?

USB HOST IAP with The same project of "STM32F105_107_AN3354_FW_V1.0.0" and exactly the same peripheral circuit(25MHz oscillator), it succeeded by using STM32F107VCT6, but failed by using STM32F107RCT6. Please tell my why, it makes me crazy�?

EEPROM EMULATION STM32f103

How can I store characters in flash memory of STM32F103 using HAL C coding?? I am able to store hex values in flash but no idea on how to save char values.
