ÚčastníkZdravím 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.#include <avr/pgmspace.h> #include <LedControl.h> typedef const unsigned char prog_uchar ; //tento řádek přidat pokud se objeví chyba: prog_uchar does not name a type // *CONSTANTS const int DIN = 12; const int CLK = 11; const int LOAD = 10; const int numDevices = 1; //Počet použitých modulů MAX7219 LED Driver Chips (1-8) const long scrollDelay = 70; prog_uchar font5x7 [] PROGMEM = { B00000000, //Space (Char 0x20) B00000000, B00000000, B00000000, B00000000, B00000000, B00000000, 6, B10000000, //!

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…
