需要用到的三个串口输入输出函数 Serial.begin(baudrate): 这个函数用来初始化串口,设置波特率,即每秒传输的比特数。一般放在setup()函数中,例如Serial.begin(9600)表示设置波特率为9600。 Serial.print(data): 这个函数用来向串口发送数据,可以是任意类型的值,例如数字、字符串、字符等。数据会被转换为ASCII码发送,...
// This allows the connection of wireless adapters (for instance) to non-default port pins. 这允许无线适配器(例如)连接到非默认端口引脚。 // Serial port 0 is still used by the Arduino bootloader regardless of this setting. 无论此设置如何,Arduino引导加载程序仍使用串行端口0。这里选了com3端口 ...

Since Urboot has automatic baud rate detection, the upload baud rate can be changed without having to re-flash the bootloader. The default baud rate setting will pick a suited baud rate that also works with the legacy Optiboot bootloader used in earlier MegaCore versions. The other baud rate ...
If you have triple-checked all the connections but still getting errors, the problem might be the speed of the serial links. I have set the jtag2updi entry on the avrdude configuration file to run at 115200 baud by default. This baud rate can cause errors, for example, if your MCU is...
These can be either the default libraries that come with Arduino or a library that you have created yourself. If you select the Stepper library, for example, you’ll see the following line appear in the code window: #include <Stepper.h> This imports the Stepper library into the project, ...

To resolve this issue, check the COM Port and Baud Rate settings and ensure that they are correct. If the error persists, press Reset button on Arduino board and try to connect again. Data Acquisition does not start when you clickStartfor the first time. ...
