请问下关于RGBLCD的16*32字符程序该怎么写？

Belzher · 发表于 2022-8-16 22:15:59

如题，自己想显示下32*16的字符（或者说任意大小字符），自己在16*8的例程上改了下，但目前的效果是前半和后半位置反了，拼起来才可以，请大神看下程序哪里有问题？（字模取向和例程不一样）

module lcd_dis(
input lcd_pclk,
input sys_rst_n,
input [10:0] pixel_xpos,
input [10:0] pixel_ypos,
input [10:0] h_disp,
input [10:0] v_disp,
output reg [23:0] pixel_data
);

下面注释的可以不用看，我还待修改，我觉得主要是if(numb3216[7][(FON1_Y_START+FON1_HIGHT-pixel_ypos-1)*16+((pixel_xpos-(FON1_X_START+FON1_WIDTH*1))%8)+(FON1_WIDTH/8-(pixel_xpos-(FON1_X_START+FON1_WIDTH*1))/8)*8])这段有问题，但不知道怎么改。
