我遇到的问题是,只有有时我会看GTKterm中的输出。我无法找到一个什么时候工作的模式,何时没有。我如何调试这个?
有关初学者的一些建议:
确保您的终端软件正在断言DTR信号。这是找到的解决方案。
暂时删除 power_manage()
的调用,以确保不是问题的一部分。 / p>
更改 APP_UART_FLOW_CONTROL_ENABLED
为以确定它是否为流控问题。在任何情况下,您不需要输出到PC的流量控制。如果您正在输入设备(特别是缓冲区长度为1),或者您正在向缓慢的缓冲设备发送数据,可能需要此功能。
调用,以确保在该阶段没有发生问题。定义可能的错误代码。

The problem I am having is that only sometimes I will see an output in GTKterm. I am unable to find a pattern for when it works and when it doesn't. How would I go about debugging this?
Some suggestions for starters:
Ensure that your terminal software is asserting the DTR signal. That was the solution found here.
Temporarily remove the call to power_manage()
to ensure that is not part of the problem.
Change APP_UART_FLOW_CONTROL_ENABLED
for APP_UART_FLOW_CONTROL_DISABLED
to determine whether it is a flow control issue. You will not need flow control for output to a PC in any case. It may be needed if you are inputting to the device (especially with a buffer length of 1) or if you are sending to data to a slow device with limited buffering.
Verify ERR_CODE
after calling APP_UART_FIFO_INIT
to ensure no problems occurred at that stage. Possible error codes are defined here.
