Based on Larry's SMART Response XE support library Features: -------- 1) LCD initialization (4-gray levels) and support to draw 4 sizes of characters and outline+filled rectangles 2) Functions to erase/write/read the external 128K byte SPI FLASH memory 3) Fast GPIO access with simplified pin numbering (e.g. PORTD bit3 = pin 0xD3) 4) Scan the keyboard and return pressed keys translated with the shift/sym keys Installation: ------------ 1) Download the library: https://github.com/bitbank2/SmartResponseXE/archive/master.zip 2) (In the Arduino IDE) Sketch > Include Library > Add .ZIP Library > select the downloaded file > Open Getting Started: --------------- The first thing to do is initialize and clear the LCD. The pin numbers for the SRXE are: // CS, D/C, RESET SRXEInit(0xe7, 0xd6, 0xa2); // initialize display Next, you can draw some text or rectangles. The color can be 0-3 (0=off, 3=fully on) SRXEWriteString(0,120,"Hello World!", FONT_LARGE, 3, 0); // draw large black text at x=0,y=120, fg=3, bg=0 I have added some modification to Larry's work // 18/11/2019 fdufnews keyboard map modification // DEL --> enter (0x0D) (more intuitive position) // shift + DEL --> backspace (0x08) // SYM + I --> ; // SYM + Z --> * // SYM + X --> / // square root --> ESC // 8/12/2019 fdufnews added function to define scroll area // Set Scroll Area // inputs: // TA: top fixed area // SA: scroll area // BA: bottom fixed area // TA + SA + BA = 160 // // fdufnews 12/2019 // void SRXEScrollArea(int TA, int SA, int BA) // SRXELoadBitmapRLE // load a bitmap in the display RAM // input // x, y coordinate of top left in the display // btmp array containing the bitmap compressed with RLE // void SRXELoadBitmapRLE(int x, int y, const uint8_t *btmp) The bitmap is generated with generateBitmap
