Function Documentation
◆ handleUDP()
| void handleUDP | ( | ) |
Handles incoming UDP packets.
This function processes UDP packets, checks for configuration messages, and updates the LED strip accordingly.
- Parameters
-
None
- Returns
- None
- Precondition
- UDP connection is established and packets are being received.
- Postcondition
- LED strip is updated with new colors and settings.
- Note
- This function is called repeatedly to handle incoming UDP packets.
- Uses global variables such as currentMillis2, previousMillis2, interval, checkit, and packetBuffer.
- Calls other functions such as Udp.read(), EEPROM.write(), and FastLED.showColor().
18 {
19 if (currentMillis2 - previousMillis2 > interval * 2) { //message received after long wait, may be config message? check it
20 // save the last time you checked the time
22 //check the UDP packet for correct config message values later:
24 }
27
28 // read the packet into packetBufffer
