From e32951b525c5cd67aece0dffb7d4012b1567dcaf Mon Sep 17 00:00:00 2001 From: Andreas Neubacher Date: Thu, 21 Jan 2016 13:06:32 +0100 Subject: lcd: fix the color testpattern in 16bit mode The testpattern of the lcd was only working in 8bit mode(2x3 tiles in different colors). With this patch now 8bit and 16bit is supported. In 16bit mode there are 2x4 tiles in different colors. The number of LCD-colors is defined in the include/configs/.h Signed-off-by: Andreas Neubacher Signed-off-by: Anatolij Gustschin --- common/lcd.c | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) (limited to 'common/lcd.c') diff --git a/common/lcd.c b/common/lcd.c index 2f3594a..51705ad 100644 --- a/common/lcd.c +++ b/common/lcd.c @@ -89,13 +89,24 @@ static void lcd_stub_puts(struct stdio_dev *dev, const char *s) /* Small utility to check that you got the colours right */ #ifdef LCD_TEST_PATTERN +#if LCD_BPP == LCD_COLOR8 #define N_BLK_VERT 2 #define N_BLK_HOR 3 static int test_colors[N_BLK_HOR * N_BLK_VERT] = { CONSOLE_COLOR_RED, CONSOLE_COLOR_GREEN, CONSOLE_COLOR_YELLOW, CONSOLE_COLOR_BLUE, CONSOLE_COLOR_MAGENTA, CONSOLE_COLOR_CYAN, +}; /*LCD_BPP == LCD_COLOR8 */ + +#elif LCD_BPP == LCD_COLOR16 +#define N_BLK_VERT 2 +#define N_BLK_HOR 4 + +static int test_colors[N_BLK_HOR * N_BLK_VERT] = { + CONSOLE_COLOR_RED, CONSOLE_COLOR_GREEN, CONSOLE_COLOR_YELLOW, CONSOLE_COLOR_BLUE, + CONSOLE_COLOR_MAGENTA, CONSOLE_COLOR_CYAN, CONSOLE_COLOR_GREY, CONSOLE_COLOR_WHITE, }; +#endif /*LCD_BPP == LCD_COLOR16 */ static void test_pattern(void) { @@ -104,12 +115,15 @@ static void test_pattern(void) ushort v_step = (v_max + N_BLK_VERT - 1) / N_BLK_VERT; ushort h_step = (h_max + N_BLK_HOR - 1) / N_BLK_HOR; ushort v, h; +#if LCD_BPP == LCD_COLOR8 uchar *pix = (uchar *)lcd_base; +#elif LCD_BPP == LCD_COLOR16 + ushort *pix = (ushort *)lcd_base; +#endif printf("[LCD] Test Pattern: %d x %d [%d x %d]\n", h_max, v_max, h_step, v_step); - /* WARNING: Code silently assumes 8bit/pixel */ for (v = 0; v < v_max; ++v) { uchar iy = v / v_step; for (h = 0; h < h_max; ++h) { -- cgit v1.1
