MCU 菜鸟一名。最近调试 lpc1850 LCD 。lcd 主函数如下。lcd 的结构体 const LCD_CONFIG_T EA800x480 已经按照 lcd 的 datasheet 修改了，目前 lcd 屏只有一个光标。 而 看代码，可以发现 for 循环是要在 lcd 上显示 nxp 的 ** 的，但是现在 lcd 屏上没有显示。 谁调试过 1850 的 lcd 屏，请给点提示吧？
int main(void)
{
uint32_t i, j;
int cursor_x = 100, cursor_y = 150;
int16_t tmp_x = -1, tmp_y = -1;
SystemCoreClockUpdate();
Board_Init();
Chip_LCD_Init(LPC_LCD, (LCD_CONFIG_T *) &BOARD_LCD);
//Board_LCD_Init(); // 用 sspi 通信 的小的 lcd 屏
SysTick_Config(SystemCoreClock / 1000);
msec = 5;
while (msec) {}
// delayMs(10000);
/* Fill Colorbar only*/
for (i = 0; i < LCD_WIDTH * LCD_HEIGHT / 4; i++)
framebuffer[i] = 0x1F;
for (i = LCD_WIDTH * LCD_HEIGHT / 4; i < LCD_WIDTH * LCD_HEIGHT * 2 / 4; i++)
framebuffer[i] = 0x3F << 5;
for (i = LCD_WIDTH * LCD_HEIGHT * 2 / 4; i < LCD_WIDTH * LCD_HEIGHT * 3 / 4; i++)
framebuffer[i] = 0x1F << 11;
for (i = LCD_WIDTH * LCD_HEIGHT * 3 / 4; i < LCD_WIDTH * LCD_HEIGHT; i++)
framebuffer[i] = 0xFFFF;
/* Fill NXP ** */
for (j = 0; j < **_HEIGHT; j++)
for (i = 0; i < **_WIDTH; i++)
putpixel(i, j, image[(i + j * **_WIDTH)]);
Chip_LCD_Init(LPC_LCD, (LCD_CONFIG_T *) &BOARD_LCD);
//Board_InitTouchController();
Chip_LCD_SetUPFrameBuffer(LPC_LCD, (void *) framebuffer);
Chip_LCD_PowerOn(LPC_LCD);

Chip_LCD_Cursor_SetClip(LPC_LCD, CURSOR_H_OFS, CURSOR_V_OFS);
Chip_LCD_Cursor_SetPos(LPC_LCD, cursor_x, cursor_y);
Chip_LCD_Cursor_Enable(LPC_LCD, 0);
/* Turn on backlight */
Board_SetLCDBacklight(1);

cursor_y = tmp_y;
}
if (LCD_WIDTH < cursor_x) {
cursor_x = LCD_WIDTH - CURSOR_H_OFS;
}
if (LCD_HEIGHT < cursor_y) {
cursor_y = (LCD_HEIGHT - CURSOR_V_OFS);
}
Chip_LCD_Cursor_SetPos(LPC_LCD, cursor_x, cursor_y);
}
