+## 命令格式
-### 波形发生器部分
+----
-Commands that provide access to **Arbitrary Waveform Generator** data and functions.
+  * 下面的JSON数据已扩展以提高可读性。在传输之前，应将所有JSON缩小（删除空白）.
+  * 除非另有说明，否则使用HTTP时，所有命令均使用POST方法发送.
+  * 所有Digilent Instrumentation协议命令必须是JSON对象或分块传输:
+    * **JSON对象**
+      * 必须以'{'字符开头，并以'}'字符结尾.
+      * 可能后跟一个或多个'\ r \ n'.
+    *  **大块转移**
+      * 由一个或多个块组成.
+      * 每个块必须以ASCII十六进制格式的块中的字节数开头，后跟一个'\ r \ n'，二进制数据和一个'\ r \ n'.
+        * 块长度在块长度和数据之间不包含'\ r \ n'.
+        * 块长度不包含二进制数据后的尾随'\ r \ n'.
+      * 每个分块传输都以零长度的分块终止.
+      * Ex.
+<code>
+\r\n
+chunk1\r\n

+E\r\n
