Official firmware 官方固件

Choose a release, set your flash options, and keep the serial monitor open while Sticky comes back to life. 选择版本、设置烧录参数，并在 Sticky 重启运行时保留串口监视器。

Step 1 步骤 1

Version and setup 版本与准备

Firmware source 固件来源 Firmware version 固件版本

Install the official Seeedash-ready firmware for reTerminal Sticky, pulled straight from the latest build. 安装适配 Seeedash 的 reTerminal Sticky 官方固件，直接从最新编译版本拉取。

Step 2 步骤 2

Flash to device 烧录到设备

Standard flash only writes the firmware itself, so it suits a device that already runs the Sticky official firmware. If you have flashed other firmware before, use Erase flash + flash. 标准烧录只会给设备烧录固件，适用于设备原本就是 Sticky 官方固件的情况。如果你之前刷过其他固件，建议使用擦除后烧录。

Connect your reTerminal Sticky with a USB data cable first.

V2.1 Bin File Structure

This tool generates the current project-compatible V2.1 indexed font bin used by the firmware custom loader. All integers are little-endian. Character coverage is limited to BMP codepoints U+0000 to U+FFFF.

File Layout Summary
Header = 136 bytes. Each glyph record = 24 bytes.
Bitmap blob = packed 1bpp rows appended after the glyph table.

Placement Fields
advance moves the cursor after the glyph is drawn.
x_offset shifts bitmap placement horizontally from the cursor x.
y_offset is the project-specific vertical placement value.

Firmware draw rule: draw_x = cursor_x + x_offset draw_y = line_top + font_height - bitmap_h - y_offset

Header (136 bytes)

Offset	Size	Field	Type
0	4	char_count	uint32 LE
4	2	font_height	uint16 LE
6	1	version	uint8 (= 21)
7	1	marker	uint8 (= 0xA1)
8	64	family_name	UTF-8, zero-padded
72	64	style_name	UTF-8, zero-padded

Glyph Record (24 bytes, V2.1)

Offset	Size	Field	Type
0	2	unicode	uint16 LE
2	2	advance	uint16 LE
4	2	bitmap_w	uint16 LE
6	2	bitmap_h	uint16 LE
8	2	x_offset	int16 LE
10	2	y_offset	int16 LE
12	4	bitmap_offset	uint32 LE
16	4	bitmap_size	uint32 LE
20	4	reserved	uint32 LE

Bitmap Encoding
1bpp, row-by-row, MSB-first, each byte inverted (~value), last byte masked.
Device decodes as Packed1BitForegroundIsZero — bit=0 is foreground ink.
