HIỂN THỊ HÌNH ẢNH DÙNG 8051 OLED
Trong hướng dẫn này, chúng ta sẽ thấy cách hiển thị hình ảnh / biểu tượng trên 128x64 OLED. Để làm điều này, chúng tôi cần hình ảnh 128x64 pixel, nếu không, chúng tôi phải cắt / thay đổi kích thước hình ảnh có độ phân giải cao hơn. Điều này có thể được thực hiện bằng cách sử dụng photoshop hoặc một số trình chỉnh sửa ảnh khác. Chúng tôi sẽ sử dụng các cửa sổ được tích hợp sẵn trong công cụ PAINT.
