掌控板micropython编程实现OLED中bmp图像

1.设置输出格式

打开PCtoLCD2002软件，点击“选项”菜单，设置选项如图1所示。其中，点阵格式：阴码；取模走向：顺向；输出数制：十六进制。设置自定义格式设置如图1所示。

图1 “选项”设置

2.生成字模

打开“文件”菜单下的“打开”菜单项，选择要显示的bmp格式文件，如图2所示。打开logo.bmp文件后，在软件中显示打开的bmp文件点阵图像，如图3所示。点击“生成字模”按钮，在软件的下方生成了bmp文件的图像点阵十六进制数据，如图4所示。

3. 图像点阵数据处理

复制生成的图像点阵数据到记事本中，提取数据部分，去掉多余的信息，数据如下所示：

由于SSD1106 OLED是单色模式，即每个像素的颜色不是黑就是白色，用二进制表示就是0或1。在选项设置时，使用的是阴码，因此0代表黑色，1代表白色。若选项设置的是阳码，则1代表黑色，0代表白色。生成的数据是16列64行，每一个十六进制数据代表8个像素的颜色。若数据是0xFC，则对应的二进制数是11111100，即所对应的8个像素的颜色分别是“白白白白白白黑黑”。SSD1106 OLED的分辨率是128*64，所以每一行的16个十六进制数是64 * 8=128。

# bmp[(y * 128 + x) // 8]计算了当前像素点在 bmp 数组中的字节位置。由于每个字节包含8位，所以需要将像素的总数量除以8来得到字节索引。
# >> (7 - (x % 8))这部分将当前像素点在字节中的位移动到最低位（即右边第一个位）。因为位图的存储通常是从高位到低位，所以需要将当前像素点的位右移，使其成为最低位。
# & 1这部分是将移动后的位与1进行按位与操作，这样可以获取当前像素点的值，要么是0（黑色），要么是1（白色）。

6. python编程实现提取bmp图像点阵数据

除了使用软件生成图像点阵数据，也可以使用python编程实现了提取bmp图像点阵数据，并在运行结果中打印二进制，显示OLED显示效果。代码如下：

from PIL import Image  def bmp_to_black_white_c51(bmp_path, output_byte_array):  # 打开BMP文件  img = Image.open(bmp_path).convert('L')  # 转换为灰度图  # 应用阈值将灰度图转换为黑白图  threshold = 128  bw_img = img.point(lambda p: p > threshold and 255 or 0, '1')  # 获取图像的宽度和高度  width, height = bw_img.size  # 初始化一个空的字节数组来存储结果  byte_data = bytearray()  # 遍历图像的每一行和每一列，将每8个像素打包成一个字节  for y in range(height):  for x in range(0, width, 8):  # 每次处理8个像素  byte_value = 0  for bit in range(8):  try:  pixel = bw_img.getpixel((x + bit, y))  byte_value = (byte_value << 1) | (pixel // 255)  # 将像素值（0或255）转换为0或1  except IndexError:  # 如果x+bit超出了图像的宽度，则忽略这些像素（填充0）  byte_value = (byte_value << 1) | 0  byte_data.append(byte_value)  # 将字节数组转换为16进制字符串列表（每两个字节一个字符串），适用于C51格式  hex_strings = ['{:02X}'.format(byte) for byte in byte_data]  combined_hex = []  for i in range(0, len(hex_strings), 8):  # 假设每8个字节（64个像素）合并一次（这里仅为示例）  byte_group = hex_strings[i:i+8]  combined_value = int(''.join(byte_group), 16)  # 将8个16进制数字符串合并为一个整数  combined_hex.append('{:016X}'.format(combined_value))  # 转换为16位的16进制字符串  output_byte_array.extend(byte_data)  # 将处理后的字节数据添加到输出字节数组中  output_data = bytearray()  
bmp_to_black_white_c51('logo.bmp', output_data)  # 打印输出字节数组的二进制表示（用于验证）  
print('Output byte array in hex:')  
for i,byte in enumerate(output_data):print(f'{byte:08b}', end='') if (i + 1) % 16 == 0 or i == len(output_data) - 1:print('')# 将输出字节数组保存到文件  
with open('output_data.txt', 'w') as f:  f.write('bytearray([\\ \n')  for i, byte in enumerate(output_data):  f.write(f'0x{byte:02X}')  if (i + 1) % 16 == 0 or i == len(output_data) - 1:  # 每行16个字节，最后一个字节后也换行  f.write(',\n')  else:  f.write(',')  f.write('])\n')

打印的二进制数据如图6所示。
