给你个思路，可以上位机取汉字字模，网络直接传输字模数据，下位机直接显视就好，以节省单片机宝贵的硬件资源。 下面是用于生产环境的C#相关代码。请参考。
#region 下位机字模相关
public static string GetHZK12String(string Source)
{
if (Source!=null&&Source.Length<4&&Source.Length>0)
{
StringBuilder sb = new StringBuilder();
for (int i = 0; i < Source.Count() ; i++)
{
//获取汉字的信息
sb.Append(GetHex(GetByte( Source.Substring(i,1))));
}
var s = sb.ToString();
return s.Substring(0, s.Length - 1);
}
else
{
var temp = "未实名";
StringBuilder sb = new StringBuilder();
for (int i = 0; i < temp.Count(); i++)
{
//获取汉字的信息
sb.Append(GetHex(GetByte(temp.Substring(i, 1))));
}
var s = sb.ToString();
return s.Substring(0, s.Length - 1);
}
}
