Installing Software

One-line Installer

We've created a super-easy installation script that will install all pre-requisites and get your HAT up and running in a jiffy. To run it fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop like so:

In the new terminal window type the following and follow the instructions:

curl -sS get.pimoroni.com/skywriter | bash

From PyPi (Stable)

Install smbus:

sudo apt install python3-smbus

Enable i2c:

sudo raspi-config nonint do_i2c 0

Install the library:

python3 -m pip install skywriter

From Source (Unstable/Latest)

Install smbus:

sudo apt install python3-smbus

Enable i2c:

sudo raspi-config nonint do_i2c 0

Install the library:

git clone https://github.com/pimoroni/skywriter-hat
cd skywriter-hat/python/library
python3 setup.py install

Skywriter to Pi Connection

You can use a full-sized Skywriter board with your Raspberry Pi and our library by mimicking the connections that the HAT users. They are as follows:

Skywriter	Raspberry Pi
GND	GND
TRFR	GPIO 27
RESET	GPIO 17
SCL	GPIO 3 / SCL
SDA	GPIO 2 / SDA
VCC	3V

skywriter-hat's Issues

Multiples Skywriters on one arduino board?

I see that the I2C address for the skywriter it's hardcoded SW_ADDR 0x42, would be possible assign different address to multiples Skywriter boards? therefore using only one Arduino to connect two or more skywriter boards?

do you have library for processing?

Install script issues

I noticed a few issues when trying to setup the Skywriter HAT:

When running the install script on a clean install of the latest Raspbian Jessie (Lite) image (on a Pi 3 in my case), it appears to be running fine the first time.

1. The install script appears to fail when trying to enable I2C.
   Manually enabling I2C through raspi-config works.
2. When importing the skywriter Python library, a RPi.GPIO warning is shown regarding an already-in-use channel. Although this can be ignored using GPIO.setwarnings(False) as the library works fine, it's obviously not the best option.
3. When re-running the install script, it fails on trying to install smbus.

AttributeError: 'AsyncWorker' object has no attribute 'isAlive'

Raspberry Pi Zero W
Raspberry Pi OS 11 (bullseye)
Python 3.9

This is the error I received when running the test.py example that comes with the full install of the Skywriter. I have fixed the issue by editing "/usr/lib/python3/dist-packages/skywriter.py" lines 93 & 98. See full error message below the solution.
Line 93: "if self.isAlive() == False:" to "if self.is_alive() == False:".
Line 98: "if self.isAlive() == True:" to "if self.is_alive() == True:".

deactivate auto-calibration

Hello,

Have you a method for deactivate the auto calibration on MGC3130 ?
I need detect a motionless body.

Thanks

Best regards

IOError: [Errno 2] No such file or directory - after running rpi-update

We've become aware of an issue with the new device-tree enabled kernel which requires i2c to be enabled in config.txt ( although I've been told this behaviour is being reverted so that i2c is enabled, but modules not inserted by default ).

If you're a regular uses of rpi-update, and you're seeing an error like this:

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    import skywriter
  File "/usr/local/lib/python2.7/dist-packages/skywriter-0.0.2-py2.7.egg/skywriter.py", line 31, in <module>
    i2c = SMBus(i2c_bus_id())
IOError: [Errno 2] No such file or directory

Then please read this thread: http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=97314

If you're here because you're seeing a similar error, but don't use rpi-update, then please try our installer script:

curl get.pimoroni.com/skywriter | bash

Exception("Skywriter encoutered nore than 10 consecutive I2C IO errors!")

Hi,
i've installed the new skywriter 3D and all works fine, but almost one or two times per day i've got this error and the script doesn't work anymore and the only way is to restart the script.
The error that appears is:

Exception in thread Thread-1:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
self.run()
File "/usr/local/lib/python2.7/dist-packages/skywriter.py", line 107, in run
if self.todo() == False:
File "/usr/local/lib/python2.7/dist-packages/skywriter.py", line 313, in _do_poll
raise Exception("Skywriter encoutered nore than 10 consecutive I2C IO errors!")

and the script is:

import skywriter
import signal

@SkyWriter.flick()
def flick(start,finish):
try:
print('Got a flick!', start, finish)
if start == "west":
print ("got west")

except:
print "ERROR"

signal.pause()

Skywriter hat cannot pick up on flicks - broken/not working?

I have recently purchased a skywriter hat and have followed all directions on installing scripts and inserting hat into GPIO pins. When I run test.py, the script does not pickup on flicks, and once, say, I touch the board, the touch is registered but then it continues to print touch even when I am not touching it. When I press control + C to cancel the script running, it continues to print out test.py. I am wondering if this is a programming error or something on the hardware side.

Installing bash script fails

Running the command, execute but fails because smbus dependency:

curl -sSL get.pimoroni.com/skywriter | bash

The raspberry pi has python versions 2.6 and 2.7 with 2.7 being the active one.

Relevant output:

Python 2 module found. Reinstall/Update? [y/N] y

  Using cached skywriter-0.0.3.tar.gz
Collecting smbus (from skywriter)
  Could not find any downloads that satisfy the requirement smbus (from skywriter)
  No distributions at all found for smbus (from skywriter)
Python 2 library install failed!

Full output:

This script will install Skywriter libraries
and dependencies for both Python 2.

This process may take several minutes.

--- Warning ---

Always be careful when running scripts and commands
copied from the internet. Ensure they are from a
trusted source.

If you want to see what this script does before
running it, you should run:
    \curl -sS get.pimoroni.com/skywriter


Do you wish to continue? [y/N] y

Skywriter requires I2C, enable now? [y/N] y

Reset not always HIGH?

Please enable internal pull-up for reset pin on Arduino when Skywriter is being initialized. Sometimes on start-up, sensor is "frozen", that is, it doesn't work until next reset. I've found out that enabling internal pull-up resistor on Arduino solves the issue, but I'm not sure why.

Change line 14 in skywriter.cpp from:
pinMode(this->rst, INPUT);
to:
pinMode(this->rst, INPUT_PULLUP);

device (XL) stopped working

Hi!

I used the hat on an teensy LC and it worked just fine.

suddenly it stopped. Didn't change anything in de code... no other simple example code can interface with de device... i2c scanner still finds it. but rest is frozen.

#include <Wire.h>
#include <skywriter.h>

unsigned int max_x, max_y, max_z;

"Airwheel" gesture never activates

I've got a Skywriter HAT attached to a Pi 4. All other gestures seem to work fine, but airwheel specifically never gets any callbacks. Even a simple callback like the below never gets called:

import signal
import skywriter

@skywriter.airwheel()
def f(delta): print(delta)

signal.pause()

I've tried distances of anywhere from barely above the surface to about 15cm above the surface — nothing seems to register.

SW_CIRCLE_C(C)LOCKWISE gesture

I cannot get SW_CIRCLE_CLOCKWISE and SW_CIRCLE_CCLOCKWISE working, when are these supposed to be activated (what gesture) and are these triggered by void gesture(unsigned char type) or by another function?

Also the documentation on the Arduino library and examples is very scarce, it could use an update.

worker.stop() AttributeError: 'NoneType' object has no attribute 'stop'

I get this error after running test.py (sudo python test.py):
Traceback (most recent call last): File "umouse.py", line 2, in <module> import skywriter File "/usr/lib/python2.7/dist-packages/skywriter.py", line 502, in <module> i2c.write_i2c_block_data(SW_ADDR, 0xa1, [0b00000000, 0b00011111, 0b00000000, 0b00011111]) IOError: [Errno 121] Remote I/O error Error in atexit._run_exitfuncs: Traceback (most recent call last): File "/usr/lib/python2.7/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/usr/lib/python2.7/dist-packages/skywriter.py", line 493, in _exit stop_poll() TypeError: 'NoneType' object is not callable Error in sys.exitfunc: Traceback (most recent call last): File "/usr/lib/python2.7/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/usr/lib/python2.7/dist-packages/skywriter.py", line 493, in _exit stop_poll() TypeError: 'NoneType' object is not callable
Can anyone help me resolve this issue?

i2c detect -y 2 gives me:
0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- 3a -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: 50 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --
and the others all produce a blank report.
Thank You.

garbage gesture

So in the documentation it says there is a garbage gesture but the wording of how that gesture is performed doesn't really clarify how to actually make this gesture. I'm working on turning a pi into a gesture based hotkey machine and that one could prove useful for closing windows or opening a terminal. But for the life of me I can't figure out how it's performed. It's in the library but there are no code examples of it. Is it not finished? And I have just been waving like a mad man for no reason?

Ability to start/stop polling as required

examples/test.py just prints firmware info

I've enabled i2c and installed the library, but when I try to run the example program all that happens is that it prints the firmware info, over and over again until i ctrl-c out of it.

If I move my hand over or tap the sensor nothing happens, except the same stream of firmware info.

Problem runnning test.py

I installed the library successfully on a RPI 2, fresh installed Raspbian (updated everything) and after a reboot:

Any idea?

Autopy not installed

With the get installer, it looks like autopy, required for the keyboard and mouse examples, isn't installed. Further, trying to pip install autopy seems to fail also on the most recent version of Jessie.

mqtt

hello

I was wondering if the software of this device can be connected to a MQTT broker and send the data to other devices via MQTT?

thanks.

Skywriter XL XYZ positions inaccurate

I have an issue with my SkyWriter XL, using the latest RPi library and having updated to the latest firmware, I am finding that the XYZ coordinates returned by the move reports are highly inaccurate and inconsistent.

For example:

• in the Horizontal (X) axis, the values I get back range from about 0.25 at the extreme left hand side to 1.0, but it reaches 1.0 when my finger is barely half way across the sensor.
• in the vertical (Y) axis, it stays at 0.0 until my finger is about a quarter of the way up from the bottom and never goes above 0.75
• the Z axis, by contrast, seems to be about correct

Is this behaviour normal for the XL, or is there a problem with my device?

Multiple detection onTouch

When using onTouch my arduino seems to be detecting multiple taps even when I tap once. And when I double tap it will detect a tap first and then a double tap. I am using the Flick Large with an Elegoo Uno R3. Any help would be much appreciated :)

void setup() {
  Serial.begin(9600);
  while(!Serial){};

  Serial.println("Hello world!");

  Skywriter.begin(10,11);

  Skywriter.onAirwheel(handleAirwheel);
  Skywriter.onGesture(handleGesture);
  Skywriter.onTouch(handleTouch);
//  Skywriter.onXYZ(xyz);

  pinMode (9, OUTPUT);
  pinMode (8, OUTPUT);

  digitalWrite(9, HIGH);
  digitalWrite(8, HIGH);
    
}

void loop() {
  Skywriter.poll();
}
void handleTouch(unsigned char type){
  if( type == SW_TOUCH_CENTER ){
     Serial.println("Centre touch");
  }

  if(type == SW_DOUBLETAP_CENTER){
    Serial.println("double tap");
  }
}

How can I run this with Arduino UNO sir?
