And now onto the code. I went through my standard steps to verify that the hardware was accessible, by downloading wiringPi and pigpio and confirming that these add-ons will access the RPi2 hardware – yes, confirmed that GPIO access was possible. The GPIO pins on a Raspberry Pi are a great way to interface physical devices like buttons and LEDs with the little Linux processor. In previous tutorials we've outlined temperature sensing, PIR motion controllers and buttons and switches, all of which can plug directly into the Raspberry Pi's GPIO ports. WiringPi is a library that is used by many applications on the Raspberry but is not available by default. Which of these is suitable for your applications depends on how many PWM outputs you need and what performance you want out of those outputs. I have a small Python class that simplifies working with the PWM sysfs interface, but it's only a convenience and definitely not required to work with the timers. 3V MCU_SWIM.

We like this arrangement, for many reasons, such as error-handling, safety interlocks, datalogging, race conditions, and many other bonus features. If you need more. It uses two pins on the Raspberry Pi. I will explain right through installing the OS, to ensure that the dependencies and everything. It's a useful reference for both experienced programmers and anyone that wants to learn the C language. That means that from Smalltalk itself you can manage the GPIO pins as well as the known protocols like 1-Wire, I2C, SPI, etc. Effectively this is a halfway house between hardware and software PWM, providing a 1 µs timing resolution compared to 100 µs with WiringPi's Software PWM[1].
