STM32 Cryptographic Library Introduction This manual describes the API of the STM32 cryptographic library (STM32-CRYP-LIB) that supports the following cryptographic algorithms:  AES-128, AES-192, AES-256 bits. Supported modes are: – ECB (Electronic Codebook Mode) – CBC (Cipher-Block Chaining) with support for ciphertext stealing – CTR (CounTer Mode) – CCM (Counter with CBC-MAC) – GCM (Galois Counter Mode) – CMAC – KEY WRAP  ARC4  DES, TripleDES. Supported modes are: – ECB (Electronic Codebook Mode) – CBC (Cipher-Block Chaining)  HASH functions with HMAC support: – MD5 – SHA-1 – SHA-224 – SHA-256  Random engine based on DRBG-AES-128  RSA signature functions with PKCS#1v1.5  ECC (Elliptic Curve Cryptography): – Key generation – Scalar multiplication (the base for ECDH) – ECDSA These cryptographic algorithms can run in the series STM32F1, STM32 L1, STM32F2, STM32F4, STM32F0 and STM32F3 with hardware enhancement accelerators.

ov9653寄存器配置，包括SXGA，VGA，QVGA，已经经过验证。-ov9653 register, including SXGA, VGA, QVGA, has been verified.

关于中心画圆算法，通过计算x = 0到 y = 0 的1/4椭圆的范围，然后通过对称原理得到其他3/4个点的信息。(R2表示椭圆厂轴的半径） -Center Circle on the algorithm, by calculating the x = 0 to y = 0 1/4 of the scope of an oval, and then adopted the principle of symmetry other 3/4 point information. (R2 that elliptical plant axis radius)

这是一个使用VC++编写的“基于BP网络的数字0-9识别”的程序，还是比较经典实用的。-It is a preparation of the VC, "based on BP"s figures 0-9 network identification" procedures, or more classic practical.
