Wenn du etwas sparen möchtest und etwas Geduld mitbringst, lohnt sich ein Blick auf AliExpress.com – dort ist das Board bereits ab rund 6 € zzgl. Versand erhältlich. Hinweis von mir: Die mit einem Sternchen (*) markierten Links sind Affiliate-Links. Wenn du über diese Links einkaufst, erhalte ich eine kleine Provision, die dazu beiträgt, diesen Blog zu unterstützen. Der Preis für dich bleibt dabei unverändert. Vielen Dank für deine Unterstützung! Lieferumfang Der Mikrocontroller wird in einer kleinen antistatischen Tüte geliefert ohne Pinleisten. Du musst dir somit noch zusätzlich eine 2,54mm Stiftleisten* besorgen. Diese Stiftleisten gibt es ebenso recht günstig auf Aliexpress oder ebay.de.

Pinout & Aufbau des Mikrocontrollers

Nachfolgend siehst du das Pinout des Mikrocontrollers. Besonders positiv fällt auf, dass es einen deutlich gekennzeichneten 5V-Pin gibt – das ist bei Mikrocontrollern der ESP32-Familie eher selten.

Pinout - ESP32-S3 Matrix Abgesehen davon sind nahezu alle GPIOs vielseitig nutzbar: Sie unterstützen UART, PWM, I2S, ADC, I2C und SPI-Kommunikation. Zusätzlich ermöglichen die beiden Pins unten rechts, TX und RX, die serielle Kommunikation mit anderen Geräten – etwa für Debugging-Zwecke oder die Anbindung externer Module. Aufbau der RGB LED Matrix Die RGB-LED-Matrix auf dem ESP32-S3-Matrix Board ist fest verlötet und folgt einem 8x8-Raster, also 64 einzeln adressierbaren LEDs. Standardmäßig ist die Matrix intern mit GPIO 14 des Mikrocontrollers verbunden – diesen Pin müssen wir auch in unserem Sketch angeben, um die LEDs korrekt anzusteuern. Die erste LED (Index 0) befindet sich dabei oben links, direkt neben dem USB-Anschluss, in der ersten Zeile. Von dort aus verläuft die Adressierung zeilenweise nach rechts, also in sogenannter „serienmäßiger Reihenfolge“ (row-major order). Das ist wichtig zu wissen, wenn man später eigene Muster oder Animationen umsetzen möchte.

Programmierung des Boards ESP32-S3-Matrix

In der offiziellen englischen Dokumentation zum Board von Waveshare wird dir erläutert wie du dieses Board in der Arduino IDE, Visual Studio Code, Espressif IDF sowie MicroPython programmierst. Ich möchte dir nachfolgend meinen Weg aufzeigen wie ich diesen in der Arduino IDE zum laufen gebracht und programmiert habe. Achtung: Helligkeit nicht zu hoch einstellen Ein wichtiger, aber leicht zu übersehender Hinweis findet sich in einem der Beispielsketches von Waveshare: Die Helligkeit der RGB-LED-Matrix sollte nicht zu hoch eingestellt werden, da sich das Board sonst stark erwärmen kann. Durch die kompakte Bauweise und die hohe Leistungsaufnahme der LEDs besteht die Gefahr, dass sich die Temperatur schnell erhöht – was auf Dauer zu einer Beschädigung der Platine führen kann. Programmieren in der Arduino IDE Die Entwicklungsumgebung Arduino IDE ist für die Mikrocontroller der Arduino-Familie (wie der Name es erahnen lässt) ausgelegt. Damit wir den Mikrocontroller mit dem ESP32-S3 Chip programmieren können, müssen wir zunächst den Boardtreiber installieren. Installieren des Boardtreibers für Espressif Chips Im ersten Schritt öffnen wir die Einstellungen – entweder über das Hauptmenü Datei > Einstellungen oder mit der Tastenkombination Strg + , (Komma).

In den Einstellungen klicken wir auf die in der zweiten Grafik markierte Schaltfläche (2), um den Dialog „Zusätzliche Boardverwalter-URLs“ zu öffnen. Dort fügen wir die folgende URL ein und bestätigen mit OK: https://espressif.github.io/arduino-esp32/package_esp32_index.json Sobald dieser Schritt abgeschlossen ist, kannst du den Boardverwalter über das linke Menü (6) öffnen und dort nach „esp32“ suchen (7). In der Ergebnisliste sollte der Eintrag „esp32 von Espressif Systems“ erscheinen. Wähle dort die Schaltfläche „INSTALLIEREN“ (8), um die Boarddefinitionen zu installieren.

Die Installation kann etwas Zeit in Anspruch nehmen, da es zahlreiche Varianten des ESP32 gibt und alle benötigten Treiber von einem eher langsamen Server heruntergeladen werden. Bei mir hat der Vorgang rund 5 Minuten gedauert. Den Fortschritt der Installation kannst du im Fenster „Ausgabe“ mitverfolgen. Damit sind die benötigten Boardtreiber installiert. Du findest nun unter Werkzeuge > Board > esp32 eine große Auswahl an ESP32-Boards. Für das hier verwendete Board wählen wir den Eintrag „ESP32-S3 Dev Module“ aus.

Programmieren der 8x8 RGB Matrix mit der Adafruit NeoPixel Bibliothek Wie man eine RGB-LED vom Typ WS2812B am Mikrocontroller ansteuert, habe ich bereits in mehreren Beiträgen gezeigt. Besonders einfach gelingt das mit der Adafruit NeoPixel Bibliothek, die ich auch in diesem Beispiel wiederverwende. - RGB Beleuchtung einfach steuern: NeoPixel Ring mit Arduino - Arduino Lektion 31: 12bit RGB NeoPixel Ring - LED-Würfel: Zufallszahlen auf der Pixelmatrix darstellen Du kannst die Bibliothek ganz bequem über den Bibliotheksverwalter der Arduino IDE installieren – inklusive aller nötigen Abhängigkeiten (engl. dependencies). Suche dazu einfach nach „Adafruit NeoPixel“ und klicke auf Installieren. Hilfsfunktion zum ansteuern einer LED via X & Y Koordinate Um eine einzelne LED auf der Pixelmatrix anzusteuern, benötigen wir ihren Index im Array. Dieser beginnt oben links bei 0 und endet unten rechts bei 63. Das direkte Arbeiten mit diesen eindimensionalen Indizes kann beim Zeichnen von Figuren jedoch schnell unübersichtlich und fehleranfällig werden. Deshalb habe ich mir eine kleine Hilfsfunktion erstellt, mit der man stattdessen über X- und Y-Koordinaten arbeiten kann. Dabei steht X für die Spalte und Y für die Zeile, was dem gewohnten Koordinatensystem entspricht. So lässt sich die Positionierung einzelner Pixel deutlich klarer und intuitiver gestalten, besonders beim Aufbau grafischer Muster in einem zweidimensionalen Array. // Gerade Verdrahtung: Zeile für Zeile von links nach rechts uint16_t xy(uint8_t x, uint8_t y) { // Die LED-Matrix ist 8 Spalten (x) breit und 8 Zeilen (y) hoch. // Die LEDs sind zeilenweise verdrahtet – also: // erste Zeile von links nach rechts (x = 0 bis 7), // dann zweite Zeile direkt danach, usw. // Um die Position (x, y) auf den eindimensionalen LED-Array-Index (0–63) zu berechnen, // multiplizieren wir die Zeilennummer mit 8 (Anzahl Spalten), um den Zeilen-Offset zu bekommen: // y * 8 = Startposition dieser Zeile im Array // Dann addieren wir die Spaltennummer x hinzu: // So ergibt sich die konkrete LED-Nummer in der 1D-LED-Liste return y * 8 + x; // Beispiel: // x = 3, y = 2 → 2. Zeile = Offset 16 → Index = 16 + 3 = 19 // Das bedeutet: Pixel an Spalte 3, Zeile 2 → LED Nr. Read the full article

Wenn du deinen ESP32 nach dem Flashen mit einer dieser Firmwares wieder in der Arduino IDE programmieren möchtest, zeige ich dir hier, wie du in wenigen Schritten den gesamten Speicher überschreibst und so den Wechsel einfach machst. https://youtu.be/wlYsI5ma7Qo In diesem Beitrag verwende ich einen ESP32-WROOM-32, der standardmäßig bereits für die Programmierung in der Arduino IDE vorbereitet ist. Für ein kleines Projekt habe ich ihn zunächst mit der aktuellen MicroPython-Firmware geflasht. Jetzt möchte ich wieder zur Arduino IDE wechseln – und das geht erfreulich einfach.

Mikrocontroller - ESP32 WROOM 32 Für diesen Wechsel benötigst du lediglich die Arduino IDE – entweder die klassische Version oder die neue 2.x-Version. Zuerst installieren wir den passenden Boardtreiber und wählen dann unter Werkzeuge > Board > ESP32 das richtige Modell aus. Danach legen wir den Port fest und können direkt das angezeigte leere Programm auf den ESP32 hochladen. Zusätzliche Bordverwalter URL für den Boardtreiber: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json Alternativ kannst du auch dieses einfache Programm verwenden: Es lässt die interne LED des ESP32 alle 0,5 Sekunden blinken und gibt gleichzeitig die Nachricht „Hallo, aus der Arduino IDE“ auf der seriellen Schnittstelle aus. // interne LED des ESP32 mit dem GPIO02 verbunden #define led 2 void setup() { //beginn der seriellen Kommunikation mit 115200 baud Serial.begin(115200); //Pin der LED als Ausgang definieren pinMode(led, OUTPUT); //Ausgabe des Textes auf der seriellen Schnittstelle Serial.println("Hallo, aus der Arduino IDE"); } void loop() { //aktivieren der LED digitalWrite(led, HIGH); //eine kleine Pause von 0,5 Sekunden delay(500); //deaktivieren der LED digitalWrite(led, LOW); //eine kleine Pause von 0,5 Sekunden delay(500); } Die Ausgabe auf der seriellen Schnittstelle sollte wie folgt sein: Hallo, aus der Arduino IDE Wenn du den Mikrocontroller über die RESET- oder BOOT-Taste neu startest, kann es vorkommen, dass zusätzliche Ausgaben erscheinen – diese stammen vom Mikrocontroller selbst. Um dies zu vermeiden, kannst du die Baudrate in der seriellen Konsole beispielsweise auf 9600 setzen; so sollte diese Meldung nicht mehr angezeigt werden. ets Jul 29 2019 12:21:46 rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:4832 load:0x40078000,len:16460 load:0x40080400,len:4 load:0x40080404,len:3504 entry 0x400805cc

Fazit - von MicroPython zur Arduino IDE am ESP32

Mit wenigen, einfachen Schritten lässt sich der ESP32 von MicroPython zurück auf die Arduino IDE umstellen.
