<![CDATA[M5StickC-Plus Buzzer not working]]>I have several M5StickC-Plus's but I cannot seem to get the buzzer to work. The factory test has code in it to use the buzzer on button press but it does not seem to work. Can someone point me to code to make this buzzer work?
Thanks.

for inspiration, we can upload this program:

#include <M5StickCPlus.h>

void setup() {
M5.begin();
M5.Lcd.setTextSize(3);
M5.Lcd.setRotation(3);
M5.Lcd.setTextColor(TFT_ORANGE);
}

void loop() {
M5.update();
soundTest();
}

void soundTest() {
for (int tone=100; tone < 4000; tone=tone+50) {
M5.Lcd.fillScreen(BLACK);
M5.Lcd.setCursor(80, 50);
M5.Lcd.printf("%d", tone);
M5.Beep.tone(tone);
M5.Beep.update();
delay(200);
}
}

According to my ears there is a definite peak about 2500 Hz, with frequencies under 250 Hz and over 3000 not audible. Your ears may vary .....

There is a way to set up PWM on a pin at a desired frequency. Also, sometimes these speakers are resonant, so much louder at a particular frequency.

Example using the API, below:

I was unable to get uiflow working on my windows 10 system.
Please provide an arduino C example.
