In this article, we cover the steps needed to use the Register callback's feature in STM32. TheNUCLEO-H503RB(with anSTM32H503RBT6microcontroller) board is used, but the steps can be easily tailored to another MCU. All the implementation was done over theSTM32CubeIDEv1.13.1but can be ...

If you want to use VirtualAlloc to set aside memory and retrieve it by pages, your first call should only do a MEM_RESERVE on the maximum size of memory you plan to use. Then when you need more, you will make another call using MEM_COMMIT to get access to the page....

Hi, I try to read value of timer of STM32L152VD and convert it to float type. The way I use is first define the below union: typedef union { uint32_t timercount;

If the device GUIDs do not match, the EVR fails to initialize.The standard mixer and presenter both use Direct3D 9, with the device GUID equal to IID_IDirect3DDevice9. If you intend to use your custom presenter with the standard mixer, the presenter's device GUID must be IID_IDirect...
