findThreshold(ctx, threshold, buffer, len)[source]¶

int findThreshold(thresholdContext *ctx, unsigned int threshold, uint16_t *buffer, int len)

Given the sampled buffer, this method returns TRUE/FALSE if threshold is reached

ctx: Threshold context

threshold: Sample threshold

buffer: Buffer with samples

len: Buffer length

getSampledWindow(freqMS, numberOfSamples, buffer)[source]¶

int getSampledWindow(unsigned int freqMS, int numberOfSamples, uint16_t *buffer)

Gets samples from the microphone according to the provided window and number of samples

freqMS: Time between each sample (in microseconds)

numberOfSamples: Number of sample to sample for this window

buffer: Buffer with sampled data

printGraph(ctx)[source]¶

void printGraph(thresholdContext *ctx)

Prints a running average of the threshold context

ctx: Threshold context
