USB DFU on STM32L496

Hello,I am trying to enable USB DFU functionality on a custom board with STM32L496 MCU.Only D+ and D- pins are routed from the USB connector to the MCU, ID is not routed at all and VBUS is only to power the board. I added a code in my firmware that j...

GPIO clock management. What are __HAL_RCC_GPIO_CLK_ENABLE/DISABLE exactly used for?

Hi everyone.I'm desiging a low power application and clearly the most intuitive wayto reduce power consumption is just to turn off what we don't need.And here a doubt about the GPIO clock management raised.AFAICT, __HAL_RCC_GPIO_CLK_ENABLE should be ...

STM32f722 USB_OTG_HS doesn't work in FS mode

Trying to connect two FS devices to an STM32F722RET. Datasheets are a little vague, but seems it should be OK as long as I don't do HS.Using cubeMX, and for the FS port (PA11/PA12) - things work great. For the HS port (configured to be host_only, F...

Resolved! Are HAL_ppp_MspInit functions the only place to initialize low level resources?

Hi everybody.I'm met several scenarios in which the use of HAL_PPP_MspInitwould be too constraining.A typical example is when I'm making a reusable library that needssome peripheral. If I initialize the low level resources for the peripheralsused by ...

Bootloader STM32F4 pin unused default status

Hello,I have a working board with a STM32F429ZIT6, 144 pin MCU, which is fine.I also can update in the field, this MCU using the internal bootloader ( AN2606). However, I ve noticed something odd.During the bootloader (using stm32flash utility UART1 ...

How can I invoke UART_Receive_IT() automatically when I receive a data?

I am new to STM32 and CubeMX. I need to write a program to send and receive data from a module via UART port. I have to send(Transmit) a data to that module(for eg. M66). Then I would return to do some other tasks. once the M66 send a response to tha...
