我使用 arduino 大约 3-4 个月。现在我在 arduino Uno 中上传草图时遇到了问题。
这发生在使用 atmel-ice 进行调试之后。我第一次尝试在 atmel studio 中使用 atmel-ice 调试代码。我按照 YouTube 上的教程视频使用 atmel-ice 调试器连接和调试 arduino uno。它从未开始调试它并因错误而关闭。之后，我尝试使用 arduino ide 以及 atmel studio 和使用 ice 上传草图，但它无法上传草图，并且在 atmel studio 中我可以在尝试调试后读取设备签名，但我无法读取设备签名。我从未接触过 atmel studio for arduino 中的保险丝设置。这是默认的。

avrdude done. Thank you.
出现上述错误。在arduino ide中。我和其他人一起阅读了类似的问题，其中一些人说它处于调试模式。但是在重新启动后，它应该会随着 uno 重置而消失。我还检查了环回它是否正常工作。这发生在我的 3 个 uno 板上，我现在只剩下 1 个。我该如何解决这个问题。我也尝试刻录引导加载程序，但也出现错误。我认为可能是保险丝的问题。我该如何解决这个问题。
如果我使用 FTDI232 编程器，它会显示
avrdude: ser_open(): can't open device ".COM13": Access is denied.
avrdude done. Thank you.
这个错误。
尝试使用 ftdi232 后得到

确保 Tx/Rx 引脚上没有输入，然后它才能工作。我已经尝试过了，并且董事会开始工作。
