In Freertos Timer use show(), the Timer will not working. #449
Description
Chip type: ESP32-C3
ESP-IDF version: V5.3.4
Arduino version: v3.1.4
I created a timer for RGB blinking.
void LED_Blink_Timer_Callback(TimerHandle_t xTimer)
{
Serial.println("LED_Blink_Timer_Callback 0");
if (!is_led_blinking)
return;
if (ledState) // Check if LED blinking is enabled
strip.setPixelColor(0, strip.Color(0, 0, 0)); // Turn off the NeoPixel
else
strip.setPixelColor(0, led_blink_color);
Serial.println("LED_Blink_Timer_Callback 1");
strip.show();
Serial.println("LED_Blink_Timer_Callback 2");
ledState = !ledState; // Toggle the LED state
}
void LED_Init(void)
{
// Initialize NeoPixel strip
strip.begin(); // Set up the NeoPixel strip
strip.setBrightness(255); // Set initial brightness (0-255)
strip.show(); // Initialize the NeoPixel strip
led_blink_timer = xTimerCreate("LED_Blink_Timer", pdMS_TO_TICKS(500), pdTRUE, NULL, LED_Blink_Timer_Callback); // Create a timer for blinking
xTimerStart(led_blink_timer, 0);
}
When the code runs to strip.show(), the timer can't keep working.
But I try to use the task to run, that's not problem.
