DS90UB988-Q1: 像素输出不平滑

Part Number: DS90UB988-Q1
Other Parts Discussed in Thread: USB2ANY

你好 我的USB2ANY设备坏了 我是直接通过串口写脚本去实现输出的，目前屏幕已经可以正常显示，但是存在的问题是屏幕显示有些许问题,屏幕边缘图像感觉有锯齿 不平滑
图像如下：

PLL配置代码如下：

from smbus2 import SMBus
import struct
bus_number = 3
bus = SMBus(bus_number)
#UB947 = int(input("请输入编码器设备地址1: "), 0)
UB988 = int(input("请输入编码器设备地址2: "), 0)
bus.write_byte_data(UB988,0x04,0xC8, force=True)

    您好，

    您是否还可以提供以下信息？

    使用的串行器-(用于说明的系统方框图)
    FPD-Link 配置(独立、单或双)和数据速率
    PCLK？
    整个 SER 的初始化脚本- DES (是否使用脚本生成工具生成初始化文件？)
    寄存器转储从988 /串行器在异常显示时(最重要!)
    谢谢！
