q.clean()orq.flush(): remove all items in the queue Interrupt safe automation is not implemented in the library. You have to manually disable/enable interrupts where required. No implementation will be made as it would be an issue when usingpeek/dropmethods with LIFO implementation: if an ...
This library allows you to communicate with I2C / TWI devices. On the Arduino boards with the R3 layout (1.0 pinout), the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. The Arduino Due has two I2C / TWI interfaces SDA1 and SCL1 are near to ...

The mechanisms implemented in this library allow any thread to dispatch an I/O request asynchronously and either continue its operation oryieldcontrol to the next scheduled thread. All I/O requests are stored in a queue and are executed within a high-priority I/O thread after acontext-switch....
函数是预定义的代码块,我们可以从程序中调用它来执行任务。在本章中,我们一直在使用print()函数。print()命令是 Python 中的内置函数。Python 中有许多预定义的函数,还有更多的函数可以使用模块来添加。有关可用函数的更多信息,请查看位于 https://docs.python.org/3/library/index.html 的Python 标准库。
