f1c100s亮了,点亮了,RTT+SPI+ST7789v四线串口屏,分享一下。

进行简单修改测试,竟然点亮了。屏幕分辨率240X320
st7789.rar
两个文件放入 rt-thread\drivers 目录
测试代码:applications\main.c

#include "rtthread.h"
#include "drv_clock.h"
#include "board.h"

#include "st7789.h"

uint8_t data[LCD_RAM_SIZE];
int main(int argc, char **argv)
{
    rt_kprintf("periph_get_pll_clk:%d\n", periph_get_pll_clk());
    rt_kprintf("cpu_get_clk:%d\n", cpu_get_clk());
    rt_kprintf("ahb_get_clk:%d\n", ahb_get_clk());
    rt_kprintf("apb_get_clk:%d\n", apb_get_clk());

    static uint16_t color;
    rt_tick_t t1,t2;

    color=0;
    while(1)
    {
        color +=0x3333;
        for(uint32_t j = 0; j < (uint32_t)Pixel_NUM; j++)
        {
            data[j * 2] = color >> 8;
            data[j * 2 + 1] =  color;
        }
        t1 = rt_tick_get();
        lcd_hw_write(0, 0, LCD_Width-1, LCD_Height-1, data, LCD_RAM_SIZE);
        t2 = rt_tick_get();
        rt_kprintf("tick = %d\r\n", t2-t1);
        rt_thread_delay(500);
    }

    return 0;
}
