哪位大侠看看串口问题

李超然2365 发表于 2015-9-5 21:50:02

现在问题串口输出可以控制计数。串口设置输入进不来，

int incomingByte =0;
int ledpin = 8; //定义数字接口13
int j=0;//初使化加数变量
int addKey =4;//定义按键为第4引脚
int buttonState = 0; //初使化按键暂存值,为了和addKey类型保持一致用int;
unsigned char showNumber ={

你的串口是怎樣接的?程式上有點不統一似的.

Serial.print(incomingByte, HEX);<- 看似接了電腦

Serial.write(&showNumber[??],8);<- 看似接了其他裝置

要大家幫忙, 也清楚說明一下你是如何連接, 執行後出了什麼問題.
"串口设置输入进不来，"<- 你如何肯定是串口輸入进不来.

那個 switch(j) 的部份也太重複了, 只要 j 是 1-100 之間, 直接Serial.write(&showNumber,8);不就行了嗎?
輸入的部份也有重複而造成點亂, 整個程式, 應該可以減少 8 成以上.

其實我比較好奇，內存沒滿嗎

目测刚用掉1K 应该还好吧

你的串口是怎樣接的?程式上有點不統一似的.

Serial.print(incomingByte, HEX);

rial.print(incomingByte, HEX);读中显液晶屏16进制码A5 5A 0683 00 00 01 00 00和我的那个 SeHEXHEX0---HEXHEX9比较输出。

if (Serial.available() > 0) incomingByte = Serial.read();读中显液晶屏16进制码A5 5A 0683 00 00 01 00 00没反应.led没有变化

buttonState = digitalRead(addKey);//将第4脚的电平赋予按键变量
if (buttonState == LOW)
{
delay(10);
if (buttonState == LOW)//机械式延时去抖
j++;//按键后变量加1；
while(!digitalRead(addKey));//等待松开按键结束，按键弹起算一次有效值
}

这个是计数液晶屏条数有变化。程序正常。是不是串口读写不能同时进行。我也是个菜鸟程序不大懂。哪位大侠帮帮忙.

这一个LOOP程序就有几百行，有些应该改成函数形式的，要调度什么的也方便点。

没有。单片就串口发送16进制数到中显液晶屏显示条数。在液晶屏设定条数串口返回16进制数到单片机。
大侠指点一二。

大 ...

你好像沒看到我在問什麼似的....我不是問你的程式在做什麼, 程式的內容我大致也明白.
而且, 你一直沒說清楚你進行了怎樣的測試, 結果出了什麼問題.

或者你確定一下, 你的显液晶屏要接收什麼格式, 你同時了兩種不同的格式去發送, 還是你想送到不同的地方:

Serial.print(incomingByte, HEX);

Serial.write(&showNumber[??],8);

你知道兩者的分別嗎?

我手上沒你的硬件, 只可以從程式上去猜, 沒有足夠的資料, 實在無能為力.
