# 檔名：main.py
# 說明：示範如何載入多個 XGLCD 字型 (.c) 並顯示文字到 ILI9341

from machine import Pin, SPI
import time
import ili9341
from xglcd_font import XglcdFont

# ------------------------------------------------------------------------------
# 1. 初始化 SPI 介面與 ILI9341 螢幕 (以 ESP32 為例)
# 若使用其他板子或在 Wokwi 模擬器，請對應硬體/虛擬腳位調整
# ------------------------------------------------------------------------------
spi = SPI(1, baudrate=40000000, sck=Pin(15), mosi=Pin(7))
cs = Pin(4, Pin.OUT)    # Chip Select 腳位
dc = Pin(6, Pin.OUT)    # Data/Command 腳位
rst = Pin(5, Pin.OUT)   # Reset 腳位

display = ili9341.Display(
    spi=spi,
    cs=cs,
    dc=dc,
    rst=rst,
    width=240,
    height=320,
    rotation=180    # 0, 90, 180, 270 均可
)


# ------------------------------------------------------------------------------
# 2. 定義字型資訊，並載入字型
# ------------------------------------------------------------------------------
fonts_info = [
    ("Wingdings26x21.c",         26, 21, 32, 50)

]

loaded_fonts = {}

for font_file, w, h, start_char, letter_cnt in fonts_info:
    try:
        font_obj = XglcdFont(path=font_file, width=w, height=h,
                             start_letter=start_char,
                             letter_count=letter_cnt)
        loaded_fonts[font_file] = font_obj
        print(f"✅ 成功載入字型: {font_file}")
    except Exception as e:
        print(f"❌ 載入字型失敗: {font_file}，錯誤: {e}")

# ------------------------------------------------------------------------------
# 3. 清除螢幕，設定背景顏色
# ------------------------------------------------------------------------------
display.clear(color=0)  # 黑色背景

# ------------------------------------------------------------------------------
# 4. 顯示不同字型的文字
# ------------------------------------------------------------------------------
start_x, start_y = 10, 10  # 起始繪製座標
line_spacing = 40          # 行距
for font_name, font_obj in loaded_fonts.items():
    print(f"顯示字型: {font_name}")
    fc = ili9341.color565(255, 255, 0)  # 黃色字體
    bc = ili9341.color565(0, 0, 0)      # 黑色背景
    
    display.draw_text(x=start_x,
                      y=start_y,
                      text="0123456789",
                      font=font_obj,
                      color=fc,
                      background=bc,
                      landscape=False,  # 直立顯示
                      spacing=1)
    start_y += line_spacing

print("✅ 所有字型顯示完成！")

# ------------------------------------------------------------------------------
# 5. 保持顯示
# ------------------------------------------------------------------------------

    time.sleep(1)
