Globale Variablen:

int pos[8] = {0,0,0,0,0,0,0,0};
int lng[8] = {1,1,1,1,1,1,1,1};

Pattern code:

case 4:
    {
        CHSV c_bg(113,100,0); 
        CHSV c_t(113,100,200);
        CHSV c_p(113,100,230);
        
        for(uint8_t x=0; x<8; x++) {
           int h=pos[x];   
           for(uint8_t y=0; y<8; y++) {  
             if(h == y) {
               hsvbuf1[x*8+y] = c_p;
             } else
             if(h < y) {       
               hsvbuf1[x*8+y] = c_t;            
             } else {

           }
 
           if(lng[x] > -pos[x]) {
             pos[x]--;
           } else {
