我得到了SainSmart Mega2560 LCD Keypad Shield Sarter 套件并想上传此 LCD 键盘的演示程序。我认为 IDE 在 Win7 x64 下运行并且驱动程序已正确安装。
我只收到错误消息
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
avrdude: stk500v2_command(): failed miserably to execute command 0x10
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
我如何检查连接是否真的存在?是否有任何已知问题?
