STM32 MCUs Products

I have a design with STM32F427IIT6 and I would like to upgrade the MCU. I need one MCU that is fully pin compatible. What is my best choice at this moment in the F7 and H7 series?

STM32F105 USB HID host

I'm developing HID Host for working with standard PC keyboards.I face with problems in function USBH_HID_GetReport from cubemx, it never returns USBH_OK. Absolutly same problem explained here http://forum.easyelectronics.ru/viewtopic.php?f=35&t=23447...

CAN I use USB OTG_HS with internal FS PHY and get RX DMA?

In the FS mode the reference manual state that  USB RX DMA is only available in HS mode. In MXCube it seems that I can set USB OTG HS and set internal Phy to "device only". Does this activate the RX DMA? ​It also seems to change the pins assignment o...

Is USB mass storage available at STM32L152-EVAL?

I'm considering to use a STM32l1's family microcontroller at my project, so, as I will need to plug a flash drive at my device, I would like to validate my concept with a evaluation board that can do this. Does my MCU's choice seem right?Does this ev...

HAL SPI transmit/receive issues

I'm trying to use the HAL SPI driver to do a basic loopback test. I fill a buffer with incrementing values, and send that out while receiving into another buffer using HAL_SPI_TransmitReceive. I have 2 separate conditions both of which show odd behav...
