Projet ESP32-S3 Matrice LED RVB 2 - Texte défilant

 // Pin oyoza na matrice ya 8×8 RGB 
const int MATRIX_PIN = 14; // esengeli kozala 14 na module oyo // Bola ya matrice (largeur na hauteur)
 const int MATRIX_WIDTH = 8; 
const int MATRIX_HEIGHT = 8; 

// Bongó ya motindo ya matrice mobimba (0–255)
uint8_t matrixBrightness = 40; // bongó ya motindo ya kati oyo esengeli mpo na lopango ya ndako // Na 
setup():
matrix.setBrightness(matrixBrightness);

Soki olobeli panneau na esika ya polele to mpo na ntango mokuse, okoki komatisa motuya oyo, kasi keba ete okota te na likolo mingi soki ozali pene ya display.

Mokanda ya Kotambwisa

Liloba ya solo ebombami lokola string. Na vidéo, mokanda ya ndakisa ezali Robojax. Okoki kobongola yango na etiketi to sikawa ya mokuse nyonso oyo olingi:

 // Mokanda ya kotambwisa na matrice ya 8×8 const char scrollText[] = "Robojax";
 // bongola oyo na sikawa na yo

Kanisa ete oyo ezali kaka matrice ya 8×8, yango wana sikawa milayi mingi ekotambwisa ntango molayi mpe ekoki kokoma makasi mpo na kotanga.

Langi ya Mokanda (Bipai ya RGB)

Langi ya mokanda ya kotambwisa esalemi na bipai ya motane, ya vert, mpe ya bleu (0–255). Na ndakisa, motane ya pete ezali (255, 0, 0), vert ya pete ezali (0, 255, 0), mpe bleu ya pete ezali (0, 0, 255). Na sketch okomona eloko lokola:

 // Langi ya mokanda (R, G, B) uint8_t textRed = 255; // bipai ya motane uint8_t textGreen = 0; // bipai ya vert uint8_t textBlue = 0; // bipai ya bleu

Mpo na kobongola langi:

• Jaune: textRed = 255; textGreen = 255; textBlue = 0;
• Cyan: textRed = 0; textGreen = 255; textBlue = 255;
• Pembe: textRed = 255; textGreen = 255; textBlue = 255;

Vidéo emoniseli mpe kosalela picker ya langi na internet mpo na koluka bipai ya RGB mpe kokoma yango na code.:contentReference[oaicite:1]{index=1}

Mpwaka ya Kotambwisa (Bozongisi kati na Frames)

Mpwaka ya kotambwisa ezwami na motuya ya bozongisi na millisecond kati na etape nyonso ya mise à jour. Motuya moke esalaka ete mokanda etambola mbangu; motuya monene ekitisaka yango. Na sketch, osengeli koluka variable lokola:

// Bozongisi kati na etape ya kotambwisa (na millisecond) int scrollDelayMs = 50;
// moke = mbangu, monene = malembe

Ndakisa:

• scrollDelayMs = 20; → kotambwisa ya mbangu.
• scrollDelayMs = 50; → mpwaka ya kati (lokola na vidéo).
• scrollDelayMs = 100; to koleka → kotambwisa ya malembe, oyo ezali pete mpo na kotanga.

Na kati ya loop(), motuya oyo esalelami na delay(scrollDelayMs); nsima ya kopesa lisusu loposo ya mokanda na esika na yango.

Etaleli ya Kotambwisa (Oponeli)

Na projet ya “kotambwisa ya mokanda ya liboso” tosalelaka mingi kotambwisa na loboko ya gauche, kasi ezali malamu kosala variable ya etaleli mpo okoki komeka etaleli mosusu na nsima (gauche, droite, likolo, na nse).

Mokemoke moko ya momesano ezali:

 // Etaleli ya kotambwisa // 0 = gauche, 1 = droite, 2 = likolo, 3 = na nse
int scrollDirection = 0; // ya liboso: kotambwisa na loboko ya gauche

Loop ya liboso etalaka scrollDirection mpe etambwisaka mokanda na etaleli oyo oponi. Mpo na Projet 2 okoki kotika yango na 0 (gauche), kasi soki okokisa sketch na nsima okoki kobakisa mikakatano lokola:

 if (scrollDirection == 0) {
// tambwisa mokanda na gauche
} else if (scrollDirection == 1) {
// tambwisa mokanda na droite
} else if (scrollDirection == 2) {
// tambwisa mokanda na likolo
} else if (scrollDirection == 3) {
// tambwisa mokanda na nse
}

Mpo na lisolo oyo tokomi kaka configuration. Mise en œuvre ya mobimba ezali eteni ya code oyo ekomami na nse ya lisolo.

Lisele

Projet 2 ebongolaka ESP32-S3 RGB LED Matrix na yo na display ya mokanda ya pete kasi oyo ezali kokamata miso. Na kobongola kaka variables moke na likolo ya code, okoki mbala moko kobongola:

• Sikawa oyo emonisami (scrollText).
• Langi ya mokanda (textRed, textGreen, textBlue).
• Bongó ya motindo ya matrice (matrixBrightness).
• Mpwaka ya kotambwisa (scrollDelayMs).
• Etaleli ya kotambwisa (scrollDirection, soki oponi kosalela yango).

Sketch ya mobimba mpo na projet oyo ezali na nse ya lisolo oyo (ezali kokotama na website automatiquement). Mpo na configuration ya etape na etape mpe ndakisa ya bomoi ya mokanda ya kotambwisa na mosala, tala eteni oyo elandi na vidéo. Soki olingi projet oyo mpe olingi kosala yango moko, okoki mpe kosomba module ya ESP32-S3 RGB LED Matrix na ba liens affiliés oyo ezali na nse ya code.
