专用于UM2的3D打印机的固件，最近为研发稳定性更高、智能性更好的桌面级3D打印机而再次修改源代码，完全开源，欢迎大家下载一起研究。

四轴飞行器STM32源码,飞控信号SBUS信号解析为PWM信号输出  1.修改STM32时钟频率SBUS协议：使用的是串口的通讯，直接可以用串口发出，但有几点仍需要注意： 1.串口配置：100k波特率，8位数据位（在stm32中要选择9位），偶校验（EVEN),2位停止位，无控流，25个字节， 2.协议格式：（8字节） [startbyte] [data1][data2]……[data22][flags][endbyte] startbyte=0x0f; endbyte=0x00; flags标志位我没有用到； data1…data22:对应16个通道（ch1-ch16），每个通道11bit（22*8=16*11=176）; 数据范围在0-2047之间，基本上是1102~1927，中值为1500；

用三元组建立两个矩阵a，b，将a矩阵转置，，然后将转置后的a矩阵与b矩阵相乘，存储到c三元组中，，输出a，b，c矩阵(Create a matrix with two triplets, b, to a matrix transpose, and the transposed matrix of a matrix multiplication with b, c triples stored in the output a, b, c matrix)

这个函数分配一个数据缓冲区与多个颜色指定系统上的乐队。这种类型的缓冲区允许表示彩色图像(例如,RGB)。 这个函数为每个指定分配缓冲区,一个二维表面颜色乐队。您可以使用MbufAlloc1d()和MbufAlloc2d()来创建单独的乐队一或二维 数据缓冲区,分别。 分配一个缓冲区后,我们建议您检查是否操作成功,使用MappGetError(),或通过验证,不是M_NULL返回的缓冲区的标识符。(This function allocates a data buffer with multiple color bands on the specified system. This type of buffer allows for the representation of color images (for example, RGB). This function allocates buffers that have a two-dimensional surface for each specified color band. You can use MbufAlloc1d() and MbufAlloc2d() to create single band one- or two-dimensional data buffers, respectively. After allocating a buffer, we recommend that you check if the operation was successful, using MappGetError(), or by verifying that the buffer identifier returned is not M_NULL.)
