souci pour défiler du texte sur une matrice 16x16
Bonjour,
J'ai pour projet de réaliser une matrice led 16x16 qui affichera du texte et autres motifs.
Étant débutant avec l'arduino, j'ai essayé par moi même de créer un code pour mon projet,
mais devant la complexité du code (ou je suis pas doué), je me suis retranché sur le net, et j'ai trouve un code fonctionnant avec deux registres à décalage 74hc595 et une matrice 8x8.
Je souhaiterai donc modifier ce montage et ce code pour faire une matrice 16x16.
Après quelques bidouillages sur le code je n'arrive pas à mes fins
Je viens donc vous demandez votre aide
Code:const int clockPin = 13; const int dataPin = 11; const int latchPin = 10; byte arrow[8]={0x18,0x3C,0x66,0xDB,0x18,0x18,0x18,0x18}; byte displayBuffer[8]= {0}; int fontDefinitions[480] = { 0x00,0x00,0x00,0x00,0x00,/*space*/ // is 32 in ASCII 0x00,0xF6,0xF6,0x00,0x00,/*!*/ 0x00,0xE0,0x00,0xE0,0x00,/*"*/ 0x28,0xFE,0x28,0xFE,0x28,/*#*/ 0x00,0x64,0xD6,0x54,0x08,/*$*/ 0xC2,0xCC,0x10,0x26,0xC6,/*%*/ 0x4C,0xB2,0x92,0x6C,0x0A,/*&*/ 0x00,0x00,0xE0,0x00,0x00,/*'*/ 0x00,0x38,0x44,0x82,0x00,/*(*/ 0x00,0x82,0x44,0x38,0x00,/*)*/ 0x88,0x50,0xF8,0x50,0x88,/***/ 0x08,0x08,0x3E,0x08,0x08,/*+*/ 0x00,0x00,0x05,0x06,0x00,/*,*/ 0x08,0x08,0x08,0x08,0x08,/*-*/ 0x00,0x00,0x06,0x06,0x00,/*.*/ 0x02,0x0C,0x10,0x60,0x80,/*/*/ 0x7C,0x8A,0x92,0xA2,0x7C,/*0*/ 0x00,0x42,0xFE,0x02,0x00,/*1*/ 0x42,0x86,0x8A,0x92,0x62,/*2*/ 0x44,0x82,0x92,0x92,0x6C,/*3*/ 0x10,0x30,0x50,0xFE,0x10,/*4*/ 0xE4,0xA2,0xA2,0xA2,0x9C,/*5*/ 0x3C,0x52,0x92,0x92,0x0C,/*6*/ 0x80,0x86,0x98,0xE0,0x80,/*7*/ 0x6C,0x92,0x92,0x92,0x6C,/*8*/ 0x60,0x92,0x92,0x94,0x78,/*9*/ 0x00,0x00,0x36,0x36,0x00,/*:*/ 0x00,0x00,0x35,0x36,0x00,/*;*/ 0x10,0x28,0x44,0x82,0x00,/*<*/ 0x28,0x28,0x28,0x28,0x28,/*=*/ 0x00,0x82,0x44,0x28,0x10,/*>*/ 0x40,0x80,0x8A,0x90,0x60,/*?*/ 0x7C,0x82,0xBA,0xBA,0x62,/*@*/ 0x3E,0x48,0x88,0x48,0x3E,/*A*/ 0xFE,0x92,0x92,0x92,0x6C,/*B*/ 0x7C,0x82,0x82,0x82,0x44,/*C*/ 0xFE,0x82,0x82,0x82,0x7C,/*D*/ 0xFE,0x92,0x92,0x92,0x82,/*E*/ 0xFE,0x90,0x90,0x90,0x80,/*F*/ 0x7C,0x82,0x82,0x8A,0x4E,/*G*/ 0xFE,0x10,0x10,0x10,0xFE,/*H*/ 0x82,0x82,0xFE,0x82,0x82,/*I*/ 0x84,0x82,0xFC,0x80,0x80,/*J*/ 0xFE,0x10,0x28,0x44,0x82,/*K*/ 0xFE,0x02,0x02,0x02,0x02,/*L*/ 0xFE,0x40,0x20,0x40,0xFE,/*M*/ 0xFE,0x60,0x10,0x0C,0xFE,/*N*/ 0x7C,0x82,0x82,0x82,0x7C,/*O*/ 0xFE,0x90,0x90,0x90,0x60,/*P*/ 0x7C,0x82,0x82,0x86,0x7E,/*Q*/ 0xFE,0x90,0x98,0x94,0x62,/*R*/ 0x64,0x92,0x92,0x92,0x4C,/*S*/ 0x80,0x80,0xFE,0x80,0x80,/*T*/ 0xFC,0x02,0x02,0x02,0xFC,/*U*/ 0xF8,0x04,0x02,0x04,0xF8,/*V*/ 0xFC,0x02,0x0C,0x02,0xFC,/*W*/ 0xC6,0x28,0x10,0x28,0xC6,/*X*/ 0xC0,0x20,0x1E,0x20,0xC0,/*Y*/ 0x86,0x8A,0x92,0xA2,0xC2,/*Z*/ 0x00,0x00,0xFE,0x82,0x00,/*[*/ 0x00,0x00,0x00,0x00,0x00,/*this should be / */ 0x80,0x60,0x10,0x0C,0x02,/*]*/ 0x20,0x40,0x80,0x40,0x20,/*^*/ 0x01,0x01,0x01,0x01,0x01,/*_*/ 0x80,0x40,0x20,0x00,0x00,/*`*/ 0x04,0x2A,0x2A,0x2A,0x1E,/*a*/ 0xFE,0x12,0x22,0x22,0x1C,/*b*/ 0x1C,0x22,0x22,0x22,0x14,/*c*/ 0x1C,0x22,0x22,0x12,0xFE,/*d*/ 0x1C,0x2A,0x2A,0x2A,0x18,/*e*/ 0x10,0x7E,0x90,0x80,0x40,/*f*/ 0x18,0x25,0x25,0x25,0x1E,/*g*/ 0xFE,0x10,0x10,0x10,0x0E,/*h*/ 0x00,0x12,0x5E,0x02,0x00,/*i*/ 0x02,0x01,0x01,0x11,0x5E,/*j*/ 0xFE,0x08,0x08,0x14,0x22,/*k*/ 0x00,0x82,0xFE,0x02,0x00,/*l*/ 0x3E,0x20,0x1C,0x20,0x1E,/*m*/ 0x3E,0x20,0x20,0x20,0x1E,/*n*/ 0x1C,0x22,0x22,0x22,0x1C,/*o*/ 0x3F,0x24,0x24,0x24,0x18,/*p*/ 0x18,0x24,0x24,0x3F,0x01,/*q*/ 0x3E,0x10,0x20,0x20,0x10,/*r*/ 0x12,0x2A,0x2A,0x2A,0x04,/*s*/ 0x00,0x10,0x3C,0x12,0x04,/*t*/ 0x3C,0x02,0x02,0x02,0x3E,/*u*/ 0x30,0x0C,0x02,0x0C,0x30,/*v*/ 0x38,0x06,0x18,0x06,0x38,/*w*/ 0x22,0x14,0x08,0x14,0x22,/*x*/ 0x38,0x05,0x05,0x05,0x3E,/*y*/ 0x22,0x26,0x2A,0x32,0x22,/*z*/ 0x00,0x10,0x6C,0x82,0x82,/*{*/ 0x00,0x00,0xFF,0x00,0x00,/*|*/ 0x04,0x02,0xFF,0x02,0x04,/*|, arrow*/ 0x82,0x82,0x6C,0x10,0x00,/*}*/ 0x08,0x10,0x18,0x08,0x10/*~*/ }; void setup() { pinMode(clockPin, OUTPUT); pinMode(dataPin, OUTPUT); pinMode(latchPin, OUTPUT); } void loop() { displayString("Salut Darvock !! ceci est un test de la matrice led", 52); } void scrollBufferLeft() { for(int i=7; i>=0; i--) { displayBuffer[i+1] = displayBuffer[i]; } } void addCharSliceToBuffer(char c, byte pos) { displayBuffer[0] = fontDefinitions[((c - 32) * 5) + pos]; } void displayString(char * stringToDisplay, byte stringLength) { for(int k = 0; k < stringLength; k++) { for(int j = 0; j < 5; j++) { addCharSliceToBuffer(stringToDisplay[k], j); for(int i=0; i<20; i++) drawImage(displayBuffer); scrollBufferLeft(); } addCharSliceToBuffer(' ', 0); for(int i=0; i<20; i++) drawImage(displayBuffer); scrollBufferLeft(); } } void drawImage(byte * matrix) { for(int i=0; i<8; i++) { for(int j=0; j<8; j++) { digitalWrite(clockPin, LOW); digitalWrite(dataPin, (matrix[i]) & (1<<j) ); digitalWrite(clockPin, HIGH); } for(int j=7; j>=0; j--) { digitalWrite(clockPin, LOW); digitalWrite(dataPin, (~(1<<i)) & (1<<j) ); digitalWrite(clockPin, HIGH); } digitalWrite(latchPin,LOW); digitalWrite(latchPin,HIGH); } }
