Input = dlmread('input.csv') Run Executable program on Raspberry Pi The input.csv file contains a sample ECG signal that is used to test the deployed code. To copy files required to run the executable program, use putFile, which is available with the MATLAB Support Package for Raspberry Pi Hardware. TargetDirPath = applicationDirPaths.directory Copy Input Files to the Raspberry Pi ('applicationName','waveformSegmentation') Assuming that the binary is found in only one directory, enter: This function lists the directories of the binary files that are generated by using the codegen function. You can find the directory manually or by using the API. As a first step, copy the input ECG signal to the generated code directory. Once the code generation is complete, you can test the generated code on the Raspberry Pi. Click Next to go to the Finish Workflow page. Close the Settings window and generate code.Ĥ. The genClassifiedResults function passes the preprocessed signal to the network for prediction and displays the classification results.ģ. The performPreprocessing function preprocesses the raw signal and applies the short-time Fourier transform. It takes an ECG signal as an input and passes it to the trained BiLSTM network for prediction. In this example, waveformSegmentation is the entry-point function. All functions within the entry-point function must support code generation. You must define an entry-point function that calls code-generation-enabled functions and generates C/C++ code from the entry-point function. Generates an output file with the labels.Īn entry-point function, also known as the top-level or primary function, is a function you define for code generation. Labels regions of the signal using the pretrained BiLSTM network. Uses 15,000 samples of single-precision ECG data as input.Ĭomputes the short-time Fourier transform of the signal. ![]()
