接著要讀取第237 byte 的資料一直到最後
先來看一下規格書是怎麼說的:
根據下圖每一個 die的測試結果存放在6個 bytes 資料裡面,
例如:
第一個 byte 的14,15 bit是存放測試的結果,
0:表示沒測試
;1
:表示Pass di
e
2:表示Fail 1die;3:表示Fail 2die
那要麼取出這個 bit 呢? 很簡單將這個 byte資料右移6次的結果就是第14,15 bit 的資料:
die_test = Int(data[idx]) >> 6
再來看另外一組,如
第三個 byte 和第二個 byte 的第1個 bit是存放 Y座標值,要怎麼取出呢?
第三個 byte全部是值只要將資料轉成數字,第二個 byte的第1 bit要取出只要對它和1做 and
運算即可:(因為是高位元所以要乘上 256)
die_y = (Int(data[idx+2]) & 1)*256 + Int(data[idx+3])
最後1個 byte (0-5 bit)是存放 bin 的結果:
bin_n = Int(data[idx + 5])
看你需要讀取哪些資料就用上述方式取出,
接著再建立一個2D的陣列存放資料,由於資料會轉成字串形式因此我宣告為字串型態:
map_txt = ones(String, row, col)
這裡要注意的是通常在C或是Python陣列都是如下的格式,要儲存(取出)都是行(col),列(row)
如下圖,取出 3 的資料會寫成 a = array[2,0] ,a = 3
但在 Julia 是先 列(row),再 行(col)
這樣就可以寫個代碼來表示一下流程:
map = ones(String, row, col)
idx = 237
for r = 1 to row
for c = 1 to col
map[r,c] = read_data
idx += 6
end
end
執行後匯出的結果如下:
應該不難吧?!
這個程式會用到 檔案I/O,格式化輸出,2維陣列存取,邏輯運算子,正規式,型態轉換,
如果都能運用,基本上這個語言的基礎就都具備了。
程式碼:
using Printf

str = ""
for idx = s_pos:e_pos
str = str*Char(data_s[idx]) #combine str
end
return str
end

end
