我用的是原子的戰(zhàn)艦V4板，lcd顯示屏是在網(wǎng)上買(mǎi)的5寸屏幕，854*480的程序是正點(diǎn)提供的官方emwin例程，lcd的驅(qū)動(dòng)程序事先驗(yàn)證過(guò)能夠正常顯示包括字符串文字
lcd的畫(huà)點(diǎn)函數(shù)以及讀點(diǎn)函數(shù)等都是用的正點(diǎn)的函數(shù)，只是改了底層配置
但是跟著正點(diǎn)加入emwin的程序后就不能正常顯示移植黑屏，有沒(méi)有大佬知道具體的原因
代碼如下：
這里是單片機(jī)主程序
int main(void)
{
HAL_Init(); /* 初始化HAL庫(kù) */
sys_stm32_clock_init(RCC_PLL_MUL9); /* 設(shè)置時(shí)鐘, 72Mhz */
delay_init(72); /* 延時(shí)初始化 */
usart_init(115200); /* 串口初始化為115200 */
usmart_dev.init(72); /* 初始化USMART */
led_init(); /* 初始化LED */
lcd_init(); /* 初始化LCD */
key_init(); /* 初始化按鍵 */
sram_init(); /* SRAM初始化 */
my_mem_init(SRAMIN); /* 初始化內(nèi)部SRAM內(nèi)存池 */
my_mem_init(SRAMEX); /* 初始化外部SRAM內(nèi)存池 */
btim_timx_int_init(999,71); /* 定時(shí)1ms */
__HAL_RCC_CRC_CLK_ENABLE(); /* 使能CRC時(shí)鐘 */
GUI_Init(); /* emWin 初始化 */
// GUIDEMO_Main();
GUI_SetBkColor(GUI_RED); /* 設(shè)置背景顏色 */
GUI_SetColor(GUI_BLUE);
GUI_Clear(); /* 清屏 */
GUI_SetColor(GUI_BLACK); /* 設(shè)置顏色 */
GUI_SetFont(&GUI_Font32_ASCII); /* 設(shè)置字體 */
GUI_DispStringAt("Hello emWin!", 0, 0); /* 在指定位置顯示字符串 */
while(1);
}
下面是顯示相關(guān)的函數(shù)
static void _SetPixelIndex(GUI_DEVICE * pDevice, int x, int y, LCD_PIXELINDEX PixelIndex) {
