This PEP proposes to add time.get_clock_info(name), time.monotonic(), time.perf_counter() and time.process_time() functions to Python 3.3. Rationale If a program uses the system time to schedule events or to implement a timeout, it may fail to run events at the right moment or stop the timeout too early or too late when the system time is ... With your switch connected, let’s now look at how to read its state from Python. Start Python (as root so you can access the GPIO pins) with. sudo python In your Python console: import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) This will import the necessary libraries in the GPIO namespace and set the pin numbering to correspond to your breakout ...

  • An interrupt request (IRQ) is a hardware signal sent to the processor instructing it to suspend its current activity and handle some external event, such as a keyboard input or a mouse movement. In x86 based computer systems, IRQs are numbered from 0 to 15. Newer computers, including x86-64 systems, provide more than these 16 interrupts ...

Dec 24, 2012 · This interrupt service routine is for CCR0 only. An interrupt is thrown for CCR0 and another interrupt is thrown for the rest of the capture compare registers (CCR1, CCR2). I’ll touch on the other ISR next. The pragma is a compiler directive and the interrupt vector is defined by TIMER0_A0_VECTOR which is defined in the msp430g2553.h header file.

Apr 15, 2010 · For example, if we want a fade from brightness level 19 to 0 to take 0.5 seconds we simply divide the required time (in microseconds) by the interrupt time of 1,000 microseconds and then by the number of levels. Therefore 0.5 seconds (or 500,000 microseconds) = 500,000 / 1,000 = 500 /20 = 25. This is shown in the following code excerpt:
