怎么通过UART发送阵列

大家好，我的问题是，我想发送一个完整的数组由250个整数元素（这意味着它的大小是1000），通过UART1端口在我的PIC32 MX795F512H。下面的代码显示了我的UART的初始配置，sEndBuffd代码。我需要发送的不是很重要，有长整数。我知道如何用for循环发送它，它是有效的，但是当我实现sDeDigabuffFER发送所有数组（这实际上是我需要的）时，它也不起作用。与原始相比，我收到了不同的价值。

    Hello everybody,
My problem is that i want to send a complete array made by 250 integer elements (that means its size is 1000), through the uart1 port in my PIC32MX795F512H.

The code below shows the initial configuration of my uart, the sendbuffer code. What i need to send isn't that important, there are long integer numbers.

I know how to send it with a for loop and it works, but when i implement the senddatabuffer to send all the array (that is actually what i need) it doesn´t work as well. i receive diferent values comparing with the original.
