Zdravím všechny bastlíře a chtěl bych poprosit o radu. Stáhl jsem si knihovnu (viz. níže) na rolovací text a potřeboval bych poradit, jak přidat česká písmena a za druhé změnit směr rolovaní. Nyní se text roluje z hora dolů a potřeboval bych, aby se roloval zprava doleva. Mám tento modul a plánuji použít více modulů vedle sebe což by při současném směru rolovaní nešlo.
Předem díky za všechny rady.

Vím že ten příspěvek už je hodně starý ale možná to pomůže 😉
České charaktery si musíte dopsat sám ->
{
B00000000,
B00000000,
B00000000,
B00000000,
B00000000,
B00000000,
B00000000,
6,

V tomto poli je 7 bytů a v každém 8 bitů, každý bit reprezentuje jednu led na display a vy si musíte své charaktery „nakreslit“ do těchto bitů. Ty poté zobrazíte na display.

Pro rotování bych zkusil vypustit tuto funkci a odkazy na ní, očividně má co dělat s rotováním charakterů.

// Rotate the buffer
void rotateBufferLong(){
for (int a=0;a<7;a++){ // Loop 7 times for a 5×7 font
unsigned long x = bufferLong [a*2]; // Get low buffer entry
byte b = bitRead(x,31); // Copy high order bit that gets lost in rotation
x = x<<1; // Rotate left one bit
bufferLong [a*2] = x; // Store new low buffer
x = bufferLong [a*2+1]; // Get high buffer entry
x = x<<1; // Rotate left one bit
bitWrite(x,0,b); // Store saved bit
bufferLong [a*2+1] = x; // Store new high buffer
}

Doufám že ještě pomůžu…
