问题描述
你好!
我需要使用Visual C ++将数据发送到我的Atmega256rfr2 xplained pro。  ;
问题是视觉c ++应该是正确的因为它适用于我的arduino。此外,avr代码应该是
是正确的,因为当我使用超级终端写入它时它会起作用。
如果
有人可以告诉我这里出了什么问题我真的很感激。
这是我的visual c ++代码(部分内容)
this->serialPort1 = (gcnew System::IO::Ports::SerialPort(this->components));
//open serial port
if(!this->serialPort1->IsOpen){
this->serialPort1->PortName=this->comboBox1->Text;
this->serialPort1->BaudRate=Int32::Parse(this->comboBox2->Text);
this->serialPort1->WriteTimeout = 500;
this->serialPort1->Open();
}
//send data
if(this->serialPort1->IsOpen)
try {
this->serialPort1->WriteLine("a");}
catch(TimeoutException ^)
{
Ventanaemergente^ error = gcnew Ventanaemergente();
error->label1->Text = "Time Out Exception";
error->ShowDialog();
}
这是avr代码,
atmega led应该在收到数据时闪烁
And this is the avr code,
atmega led should blink when data is received
#include <avr/io.h>
#include <util/delay.h>
#define BAUD 9600
#define MYUBRR (F_CPU/16/BAUD-1)
int main(void)
{
UBRR1H = (unsigned char)(MYUBRR >> 8);
UBRR1L = (unsigned char) MYUBRR;
/* Enable receiver and transmitter */
UCSR1B = (1<<RXEN1)|(1<<TXEN1);
/* Set frame format: 8data, 1stop bit */
UCSR1C = (3<<UCSZ10);
/* configure led */
DDRB |= (1 << 4);
PORTB |= (1 << 4);
while(1)
{
char ReceivedByte;
while (!(UCSR1A & (1 << RXC1)));
ReceivedByte = UDR1;
PORTB &= ~(1 << 4);
_delay_ms(1000);
PORTB |= (1 << 4);
_delay_ms(1000);
}
}
推荐答案
谢谢对于你的帖子。
你的问题超出VS一般问题论坛的支持范围,该论坛主要讨论Visual Studio IDE的使用问题,例如
WPF& SL设计师,Visual Studio Guidance Automation Toolkit,开发人员文档和帮助系统
和 Visual Studio编辑器。
Your issue is out of support range of VS General Question forum which mainly discusses the usage issue of Visual Studio IDE such asWPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help Systemand Visual Studio Editor.
如果你的问题出现在C ++代码中,那么你可以在Visual C ++论坛上咨询:
。
如果问题发生在连接处或者avr代码,我不知道哪个论坛可以支持这样的问题。所以
我正在将你的问题转移到主持人论坛("论坛在哪里??")。论坛的所有者将引导您进入正确的论坛。
If the issue occurred at the connection or the avr code, I don’t know which forum can support such issue. SoI am moving your question to the moderator forum ("Where is the forum for..?"). The owner of the forum will direct you to a right forum.
致以最诚挚的问候,
这篇关于串口PC到avr问题的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
