Create a Code a simple saw wave synthesizer in micro python

Sure, here's an example code for a simple saw wave synthesizer in MicroPython:
python
Copy code
import math
import pyb
# Define the pin for the speaker output
SPEAKER_PIN = pyb.Pin("X1", pyb.Pin.OUT_PP)
# Define the frequency and duration of the saw wave
FREQUENCY = 440 # Hz
DURATION = 1000 # ms
# Calculate the number of samples to generate
SAMPLE_RATE = 8000 # Hz
NUM_SAMPLES = int(SAMPLE_RATE * DURATION / 1000)
# Generate the saw wave samples
samples = []
for i in range(NUM_SAMPLES):
sample = int(255 * (i % (SAMPLE_RATE / FREQUENCY)) / (SAMPLE_RATE / FREQUENCY))
samples.append(sample)
# Play the saw wave samples through the speaker
for sample in samples:
SPEAKER_PIN.high()
pyb.udelay(sample)
SPEAKER_PIN.low()
pyb.udelay(int((1 - sample / 255) * (1 / FREQUENCY - sample / SAMPLE_RATE) * 1000000))
This code uses the math and pyb modules, which provide functions for calculating the saw wave samples and outputting them to a speaker, respectively. The code defines the pin for the speaker output, as well as the frequency and duration of the saw wave. It then calculates the number of samples to generate based on the sample rate and duration, and generates the saw wave samples using a simple formula. Finally, it plays the saw wave samples through the speaker by toggling the speaker pin high and low with a delay between each sample to control the frequency. Note that the udelay() function is used to introduce a delay in microseconds, and the calculation of this delay takes into account the current sample value to ensure the correct frequency and waveform shape.

What can I say... just amazing...
