các pro cho E hỏi về cái lập trình Keil C cho LED matrix
E đang làm bt lớn về Mạch LED matrix 16x84, nhưng mà đang mắc cái phần viết chương trình, hôm trước E nhờ A Ngô Hải Bắc, Nhưng A đang bận
E sưu tầm dc 1 cái code trên mạng về.
code:

khai báo unsigned char code Bmp002[]={}
thì lấy những giá trị kia bằng cách nào, theo e biết đó la mã ký tự
rất mong dc các pro jup đỡ ạ
