+### How to Generate 8x16 ASCII Font Bitmaps with PCtoLCD2002
97
+
98
+**Step 1: Set the Dot Matrix Size**
99
+
100
+When choosing the dot matrix size, make sure the value is greater than the number of bytes each character uses. For example, an 8x16 character uses 8x16/8 = 16 bytes, so select a dot matrix size greater than 16.
101
+
102
+![](2025-08-19-13-07-31.png)
103
+
104
+**Step 2: Configure Character Width and Height**
105
+
106
+For 8x16 ASCII, set both the character width and height to 16.
107
+
108
+![](2025-08-19-13-07-54.png)
109
+
110
+This means each ASCII character will be 8x16 pixels, and the width will be half the value you set (since each byte represents 8 pixels horizontally).
111
+
112
+**Step 3: Input the ASCII Table**
113
+
114
+Paste the ASCII character table into the input field.
115
+
116
+![](2025-08-19-13-08-04.png)
117
+
118
+**Step 4: Generate the Font Bitmap**
119
+
120
+Click the button to generate the font bitmap. The result will look like this:
121
+
122
+![](2025-08-19-13-08-39.png)
123
+
124
+**Step 5: Use the Generated Font in Code**
125
+
126
+The 8x16 font bitmap is already provided in the sample file `lcdfont.h`, as shown below:
