以逐字模式提升角色

Question

您可以使用以下方式定义一个凸起的减号

\DefineLCDchar{rm}{00000000001111100000000000000000000}

（将减号提高一个像素）并像这样使用它

\textLCD[0]{19}|{rm}8+6|

或者，如果你想要减号总是上升，你可以用以下方式重新定义它

\DefineLCDchar{-}{00000000001111100000000000000000000}

并正常使用它（\textLCD[0]{19}|-8+6|）。在这两种情况下，结果都是

编辑：

设置\DefineLCDchar5x7 矩阵中的像素。A0表示“像素关闭”，a1表示“像素打开”。像素从左到右、从上到下排列。手册中的图片显示了这一点：
