TFT_eSprite tftSprite = TFT_eSprite(&M5.Lcd);
tftSprite.createSprite(320, 120);
while (true)
{
if(SoundWave::suspend) {
TaskHandle_t hTask = xTaskGetCurrentTaskHandle();
vTaskSuspend(hTask);
}
uint32_t ulNotificationValue = ulTaskNotifyTake(pdTRUE, xMaxBlockTime);
if (ulNotificationValue > 0)
{
tftSprite.fillSprite(TFT_BLACK);
tftSprite.drawString("hello",10,20,TFT_WHITE);
