1、复制`src\board\display\epd_configs_yzc085.c`以新的屏幕名称命名这个文件<br>
2、根据屏幕波形文档，将波形数据转成一个数组例如全刷波形数组`static const uint8_t yzc085_wave_forms_full[32][256] = {}`和局刷波形数组`static const uint8_t yzc085_wave_forms_partial[12][256] = {}`<br>
3、对应屏驱文档，修改下列函数

* 1、如果波形只支持一个温度，只需要根据刷新次数决定本次刷新使用全刷还是局部刷，并返回本次刷新需要的波形帧数，同时设置当前要用的波形表指针。根据波形表进行重新设计刷新方式。
```c

uint32_t epd_wave_table_get_frames(int temperature, EpdDrawMode mode)
{
uint32_t total_frames = 0;

if (reflesh_times % PART_DISP_TIMES == 0)
{
total_frames = sizeof(yzc085_wave_forms_full)/sizeof(yzc085_wave_forms_full[0]); //Full refresh
p_current_wave_from = &yzc085_wave_forms_full[0][0];
}
else
{
total_frames = sizeof(yzc085_wave_forms_partial)/sizeof(yzc085_wave_forms_partial[0]); //Partial refresh
p_current_wave_from = &yzc085_wave_forms_partial[0][0];
}
reflesh_times++;

return total_frames;
}
```
* 如果波形支持多个温度，可通过波形表生成不同温度的多个二维波形数组，可参考如下代码,通过温度控制不同刷新不同的数据
