这是一个参数初始化的函数调用,其中 len(x_train[0]) 是输入数据的特征数,2 是隐藏层的神经元数,1 是输出层的神经元数。函数会返回四个参数:weight1, weight2, value1, value2,分别代表第一层和第二层的权重矩阵,以及第一层和第二层的偏置向量。

SPI2_Handler.Init.CLKPolarity = SPI_POLARITY_HIGH;
This line of code sets the clock polarity for SPI2 to be high. In SPI communication, the clock signal synchronizes the data transfer between the master and slave devices. The clock polarity determines the idle state of the clock signal when it is not actively transmitting data. A high polarity means that the clock signal is idle at a high voltage level. The SPI_POLARITY_HIGH is defined as a constant value in the SPI library and is used to set the clock polarity parameter for the SPI initialization structure.
fprintf(fid1,'memory_initialization_radix=10;\n');
This line of code is used to set the format of the memory initialization file that will be written to the file with file identifier `fid1`. In this case, the radix (base) is set to 10, which means that the values in the memory initialization file will be represented in decimal format. The purpose of this line is to ensure that the memory initialization file is written in the correct format so that it can be properly read by the device or system that will be using it.
