Konečně po několika měsících
MCUFRIEND_kbv.h
jen bych potreboval pomoc s osekanim kodu....
Potreboval bych tento kod osekat tak aby mi nejezdil text na ruzny strany a byl pouze staticky...
Abych si mohl jen volit souradnice a text který tam potřebuji...
Mohl by mi někdo prosím pomoc ?
Snažím se ho co nejvíc osekat.
Potřebuji jen abych si třeba zvolil souřadnici :
10,10 zobraz text o velikosti 2 "Ahoj"
20,10 zobraz text o velikosti 3 "Nazdar"

// All the mcufriend.com UNO shields have the same pinout.
// i.e. control pins A0-A4. Data D2-D9. microSD D10-D13.
// Touchscreens are normally A1, A2, D7, D6 but the order varies
//
// This demo should work with most Adafruit TFT libraries
// If you are not using a shield, use a full Adafruit constructor()
// e.g. Adafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);
#define LCD_CS A3 // Chip Select goes to Analog 3
#define LCD_CD A2 // Command/Data goes to Analog 2
#define LCD_WR A1 // LCD Write goes to Analog 1
#define LCD_RD A0 // LCD Read goes to Analog 0
#define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin
#include <SPI.h> // f.k. for Arduino-1.5.2
#include "Adafruit_GFX.h"// Hardware-specific library
