1,更改LV的像素设置
2.更改drv_fb.c里的像素时钟设置
关于 :pixel_clock_hz
static void f1c100s_tcon_set_mode(lcd_cfg_Struct * pdat)
   val = f1c100s_tcon_clk_get_rate() / pdat->pixel_clock_hz;
   
    write32((uint32_t)&tcon->tcon0_dclk, (0xf << 28) | (val << 0));
    struct f1c100s_tcon_reg_t * tcon = (struct f1c100s_tcon_reg_t *)F1C100S_TCON_BASE;
    #define F1C100S_TCON_BASE        (0x01c0c000)

uint32_t tcon0_dclk;            /* 0x44 */

根据:  write32((uint32_t)&tcon->tcon0_dclk, (0xf << 28) | (val << 0));
lclk_en:4'hf

DCLKDIV: dot clock divider
Tdclk = Tsclk * DCLKDIV
Note:
1.if dclk1&dclk2 used，5<DCLKDIV <96
2.if dclk only，DCLKDIV >=4 || DCLKDIV=2

f1c100s_tcon_clk_get_rate()     
->  video_get_pll_clk()
->  PLL_VIDEO_CTRL_REG    0x0010  PLL_VIDEO Control Register 查看倍频情况.
这边是获取了,查一下,设置部分找到:
void rt_hw_board_init(void)
{
   
    video_set_pll_clk(198000000);

找到频的dclk,对应pixel_clock_hz改之/

void sys_clock_init(void)
->write32(F1C100S_CCU_BASE + CCU_PLL_VIDEO_CTRL, 0x81003b03);

void rt_hw_board_init(void)
->video_set_pll_clk(360000000);//(198000000);
时钟输出=24000000*(0x3b+1)/(0x03+1)=360Mhz
drv_fb.c
->lcd_cfg_Struct lcd_cfg={
    .pixel_clock_hz=60000000, //9210200,

颜色反了, write32((uint32_t)&debe->layer0_attr1_ctrl+4*LayerNum, 0x09 << 8);改成
        write32((uint32_t)&debe->layer0_attr1_ctrl+4*LayerNum, 0x09 << 8 | (1 << 2));

神奇lvgl还是反色,

运行一段时间图象抖动,加大#  define LV_MEM_SIZE    (64U * 1024U)

根据LinjieGuo的帖子 https://whycan.com/t_7659.html 做加上文件系统.
根据windoufu的帖子 https://whycan.com/t_6453.html 加上模拟u盘功能,

打包附件如下

请问RT-Thread studio集成开发环境里面可以用menuconfig修改配置吗
