Drive Adafruit’s PWM hat from C# #piday #raspberrypi @Raspberry_Pi

NewImage

Thanks to Konstantin for converting the Adafruit Python library for the PWM Raspberry Pi hat into C#! Check it out here.

I can drive Adafruit PWM hat from C#!

I converted Adafruit python code (Adafruit_PWM_Servo_Driver.py) to C# and it works!

Here is my library file:

Library (please rename to .cs)

Here is an example:

Library (please rename to .cs or copy and paste the part you need)

You will also need:

Raspberry Pi (I use the new one)

Adafruit Raspberry Pi PWM Hat (mine has PCA9685PW chip in it)

LEDs (please use resistors so you do not burn pins!)

6V power supply for the hat

Some OS installed on the PI (I use Raspbian)

Mono (mono-complete) and Mono-develop installed on the PI

These instructions look good though I did not install GTK#

RPi.I2C.Net

This library contains native code. If you use Raspbian, you might neet to re-build it. It is C++ code that need to be compiled into .so file, which will be loaded into C# managed environment. Sounds scary. Have no fear! Just ro to that folder and run “make” command – that’s it!

Device. See instructions on RPi.I2C.Net page. It adds a device – for new Raspberry PI it is “/dev/i2c-1″. If you use old raspberry, it could be different, like “/dev/i2c-0″. It is somewhere in my C# code, and if you use old Raspberry, please correct it.

So, please create a new command-line project in MonoDevelop, add RPi.I2C.Net, copy example code to the program cs and run it. make sure you adjust channel numbers. I have 6 LEDs (which are 2 RGB LEDs) on channels 0,1,2,4,5,6
My I2C address is 40 (which is default).

Sorry, my code is not industrial-strength. There is no exception handling. Please improve it if needed.

Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi – Mini Kit: The Raspberry Pi is a wonderful little computer, but one thing it isn’t very good at is controlling DC Servo Motors – these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT! It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running. Read more.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
