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...

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.

STM32F4 USB CDC and MSC class to be used for both Device-to-Host communication and Device microSD reading ? Or only CDC ?

This question is related to the code design in such a scenario when host and device communicate over USB for two purposes: two-way communication (CDC) and also host is reading the content of the Device' microSD card. The CDC mode is required in this ...
