| * File Name : lcd_pmod.h | |
| * Device(s) : RZ/T1 (R7S910017) | |
| * Tool-Chain : GNUARM-NONEv14.02-EABI | |
| * H/W Platform : RSK+RZT1 CPU Board | |
| * | |
| * Description : This Header file contains the Macro Definitions & prototypes | |
| * for the functions used in lcd.c | |
| * | |
| * This function is created to drive the Okaya LCD display with | |
| * either ST7735 or ST7715 driver device. The commands for both | |
| * the devices are the same. | |
| * | |
| * The display is controlled using the SPI bus. In this example, | |
| * the SCI5 is used. This can be modified to the SCI connected to | |
| * the PMOD interface. The SCI driver file will also be required. | |
| * | |
| * The display memory has an offset with respect to the actual | |
| * pixel. This is not documented but realised from driving the | |
| * display. The offset is set as LEFT MARGIN and TOP MARGIN. | |
| * This offset is catered for internally, so as far as the user | |
| * is concerned, cursor position 0,0 is the top left pixel. | |
| * | |
| * The simplest procedure to run the display is as follows: | |
| * Init_LCD(); Initialise the serial port and set up the display. | |
| * | |
| * Clear the display. | |
| * The font colour is set to white and background colour to black. | |
| * | |
| * DisplaySetFontColour(COL_YELLOW); | |
| * set the font colour to desired colour | |
| * DisplaySetBackColour(COL_BLUE); | |
| * set the background colour to desired value | |
| * DisplayCenter(1,"Renesas"); | |
| * write a title on line 1 of the display. | |
| * | |
| * Note: Line 0 is the top line. | |
