Define the program entry address:
#define SBL_SLV_FIRMWARE_START (0x38000)user_entry = (USER_ENTRY_PFN) *((uint32_t*)(SBL_SLV_FIRMWARE_START + 4));
Achieve redirection:

In the process of developing Android programs, it is important to identify which image format classes (ImageFormat, PixelFormat, bitmapconfig, etc.) and the image (JPG, PNG, BMP, etc.) are converted. Will play a very important role in the future development of the process. In a project development process of a software development and image processing has a close relationship, especially in mobile applications, in terms of visual effects play a crucial role, because this is related to the user e

and storage management, the APB is mainly distributed to my peripherals.The following diagram makes it easier to see the role of AHB and APB: The AHB link is the system bus, RAM, etc. APB links are commonly used peripherals: GPIO, UART, etc. the bus structure on the STM32 First look at the bus structure of the F103 series of chips It is important to note that there aretwo APB, their linked peripherals are not the same, so there are definitions of APB1 and APB2 in the STM32 library file:

Linux Kernel cardinality Tree application analysis--lvyilong316The cardinality tree (Radix trees) can be seen as a trie tree with the bits string as the keyword, a multi-fork tree structure, and similar to a multi-level index table, each intermediate node contains an array of pointers to multiple nodes, and the leaf nodes contain pointers to the actual objects ( Because the object does not have a tree node structure, it considers its parent node as a leaf node.Figure 1 is a cardinality tree samp

3. Add Dlgresize_init () in OnInitDialog (), OK
In the atlframe.h you can find the definition of dlgresize_init (), and some people used MFC to write similar code, if you are interested to compare.
Finally, do not forget to add the corresponding header file in the stdafx.h, see the source file specifically.
