sdk例程：AXI QuadSPI LVGL驱动 st77916 - minichao9901/TangNano-20k-Zynq-7020 GitHub Wiki
- AXI QuadSPI是没有问题的，虽然速度慢一点，但可以放心使用
- 最关键的是要实现填充函数
void lcdqspi_fill_pcolor(uint32_t x0, uint32_t y0, uint32_t x1, uint32_t y1, uint16_t *pcolor)
{
open_window(x0,y0,x1-x0+1,y1-y0+1);
u32 length=(x1-x0)*(y1-y0);
send_color_data(0x2C, (u8 *)pcolor, 2*length);
// send_color_data(0x2C, (u8 *)pcolor, BURST_SIZE);
// send_color_array(0x3C, (u8 *)pcolor+BURST_SIZE, 2*length-BURST_SIZE, BURST_SIZE);

- 目前暂时没有移植touch，淘宝买的屏touch调不通，看起来没有烧录固件
