  0) We are a team aspiring to attain the Goal. The Goal is to be specified at the 1st meeting.
  1) We work in two-week cycles. Each cycle is divided into two week-long subcycles.
  2) Each cycle is initiated by a meeting ("the Gathering") where all team members participate in person.
  3) The first subcycle, the first week, is the week when common team work takes place. That means that asides the Gathering, at least two additional 5-hour sessions of common hacking and exchange take place.
  4)  The second subcycle, the second week, is the consolidation week wherein everybody does his work alone. 
  5)  During the second week one aims to solve the tasks defined at the end of the first week.
  6)  The task is defined as a "challenge or problem where a solution is imaginable and/or reachable" within a week time span
  
  
  
  
  • every team member gives (him|her)self one task which can be solved within a one week span
  
  
  • every team member gives one task to the project integrator
  
  
  • project integrator attributes one task to scientific counselor
  
  
  
  In a situation where a team is composed of 1 project integrator (PI : Daniel), 1 scientific counselor (SC: Georgy), 1 engineer (ENG: Nik) and 1 data-collector (DC: Astrid), tasks are therefore distributed as follows:
  
  
  
  
  • PI: 4 tasks 
  
  
  • SC: 2 tasks
  
  
  • ENG & DC: 1 task
  
  
  
  7) At the beginning of the Gathering, everybody presents not only outcome of his efforts to solve the tasks but, more importantly, discusses problems & drawbacks which occured. Also, the failure to accomplish the task does not problem as far as one learned something in the process (e.g. that the imaginable solution is not reachable under certain constraints).

  Using QtWebKit as the back-end, it offers fast and native support for various web standards: DOM handling, CSS selector, JSON, Canvas, and SVG.

  The following simple script for PhantomJS loads Google homepage, waits a bit, and then captures it to an image.

  var page = require('webpage').create();

• X Personal Primer Project is_parent of I2c Devices Have the Same Address (ID: 5333 :: weight 1) :: TEXTREC ::
  It seems we do not need I2C multiplexers at all. Paste from https://www.instructables.com/id/Raspberry-PI-Multiple-I2c-Devices/
  
  

  An i2c bus can handle multiple devices, but they should have different i2c addresses. Some i2c devices have jumpers to set other i2c addresses, but many don't. In this case you may use a i2c multiplexer (hardware) to rotate the i2c SDA (Data) and SCL (Clock) or you can create an additional i2c bus or more.

  I will create two aditional busses, nl bus 3 and 4

  Open the cli and run

  cd /boot

  sudo nano config.txt

  Add the following line of code, preferable in the section where spi and i2c is enabled.

  dtoverlay=i2c-gpio,bus=4,i2c_gpio_delay_us=1,i2c_gpio_sda=23,i2c_gpio_scl=24

  This line will create an aditional i2c bus (bus 4) on GPIO 23 as SDA and GPIO 24 as SCL (GPIO 23 and 24 is defaults)

  Also add the following line to create i2c bus 3

  dtoverlay=i2c-gpio,bus=3,i2c_gpio_delay_us=1,i2c_gpio_sda=17,i2c_gpio_scl=27

  GPIO 17 will be the SDA and GPIO 27 will be the SCL for i2c bus 4.

  Tipe control X to exit.

  Note on the Bus Numbering and order:

  Never use bus 0 and 2, it is use for other things in the board like eprom on hats etc

  For the April 2019 raspbian release:

  You should always start with the highest bus (Bus 4 in this case) in your config.txt and work through to the lowest bus (bus 3).

  The lowest bus must always be bus 3

  If you need 5 extra busses, the busses must bi in the order of 7,6, 5, 4, 3

  This issue on bus order was not there when this Instructable was originally written. It seems like changes was made to the kernel.

  Shut down your PI, switch it of. Connect your i2c devices to bus 4 (SDA to GPIO 23 and SCL to GPIO 24) and the other to i2c bus 3 (SDA to GPIO 17 and SCL to GPIO 27).

  Switch on the pi.

  Run:

  sudo i2cdetect -l (Lower Case L)

  You will now see that i2c bus 3 and 4 is also listed. Also run:

  sudo i2cdetect -y 3

  sudo i2cdetect -y 4

  Now you can use your sensor in your programming language. Remember to specify the correct i2c busses.

  Attach is an example for the popular BMP280 Temperature and Pressure sensor. No multiplexer can read 2 BMP280s this fast.

  An example of 2 Sensirion SDP 810 sensors is also attach. Again working much faster than the multiplexer I used in the past

  GDNKNXPRMNT: Think about Your 1st Fibel Exercise
  
  Week work & outputs:
  
  Daniel
  0) Lost significant part of ERC-STG B2 DHABL project proposal. Project stalled.
  1) ge.pl encodes information about position of the correct answer within the Folio
  2) tune_bmp.sh recodes Folios to BMPs with significantly smaller size
  3) fibel's core recoded from C to C++ . extracts info about correct answer from Folio's name, compares it with user's input. correct logging.
  4) problem with gesture_combo at boot potentially resolved by adding i2cdetect into launch.sh ?
  
  Georgy:
  Pipeline mic-pyaudio-feat.extractor-NN-OSC is done.

  Pyadio callback (fixed)

  Mic triger (reduce CPU load)

  Feat extractor made with NumPy (reduce number of libraries used in pipeline)

  Optimized NN model (sliding conv layers)

  OSC output

  Whole pipeline works smoothly on Pi B (Pi Zero is too slow)

  Train server setup.(many issues... but done)

  
  

  Issues

  Pi Zero has wrong Linux distribution which slows down computation.

  Fibel service occupy all CPU resources.

  Missing hardware parts (sd card, power cables etc)

  
  

  TODO

  Train model.

  Find method to reduce false pos-neg response.

  Experiment with hop length/sampleRate for proper response of NN

  Setup GPU.

  Solve issues (see above) (Daniel, Nikoloz?)

  
  
  Nikoloz:
  1)check out if E-ink communication can be sped up

  2)write osc server to interpret commands from georgy's voice recog

  3)rewrite gesture.py to send osc messages

  4)write oop pseudocode for fibel

  5)received compute module & will start exploring

  6)started making compute module host schematics

  It may be the case that 2nd i2c bus has difficulties to initialize when battery voltage is low
  
  Potential bloody-bloody fix Fix:
  add attribute active=0 to gesture class
  add self.active=1 at the end of gesture.init() method
  Initialize the g2 like this
  
  
  

          while g2.active==0:

  
  

              try:

  
  

                  g2.init(busid2,0)

  Gathering:
  Present: all. 
  
  
  Gathering Topics: 
  1) Updates about first 2 weeks outputs *

  
  

  2) Boards, Modules for the Fibel

      Witty3 was introduced by Daniel, Nikoloz introduced the Raspberry Pi Compute Module                (+Base) and its advantages in contrast to a regular Raspberry Pi:

      reduces Space, suitable for specific task, easier to handle

  
  

    -> Discussion of approaches to reduce the size of the fibel board

  
  

  3) Presentation of Fibeltest with Child, Danger of unwanted bad teaching mentioned

  
  

  4) Discussion about content & image/sound sources(for training) for Fibel (19th century  

      images,...)

  5) Discussion about final programming language (<- question of Nikoloz)

  
  
  * Week work & outputs, issues:
  
  Daniel: 

  First approach to score a childs Fibel input,
  

  Patterns of a Childs Reading behaviour were already recognised in a first test with scoring
  

  Suggestions:  Logs should contain more information in order to analyze better the answer of the child,  Normalizing Scores 
  
  Georgy: Progress on Speechcode , More Training Data required ( "Ja", "Nein")
  

  
  

  Nikoloz: Progress on Code...
  

  
  Astrid: First attempt with Daniels Recording Software half successful
  

  
  
  TASKS:
  
  

  
  Daniel:
  1)  
  2) Georgy, please attribute me a task
  3) Nik please attribute me a task
  4) Send recorded "Ja", "Nein" to Georgy
  
  Georgy:
  1) Present Your boolean switch pipeline, comparison with other existing solution (e.g. pocketSphinx) according to a chosen metrics (e.g. F-score) & share the code
  2) Please attribute Yourself a task 
  
  Nik:

  1) speaker for prototype 0
  

  2) Send recorded "Ja", "Nein" to Georgy
  Please attribute Yourself a task

  
  Astrid:
  

  1)Recordings with Daniels improved Recording Code, Send recorded "Ja", "Nein" to Georgy.

  The model I have is ED060SCG (this one one paper should have touch functionality though idk if it can be implemented with IT8951) - costs pretty much the same as what waveshare sells.
  
  
  however if it's backwards compatible with variants from older kindles(ED060SC7(~18$) & ED060SCE(~23$, backlit)) it might be about 10$ cheaper 35%

  I updated original PaperTTY lib so there are extra features.
  it uses Pillow for images so any image format can be used (check Pillow documentation)
  plus any Pillow features for drawing, animation, text etc (Pillow is pretty powerfull for image processing)
  
  requirements for using python IT8951 lib:
  enable SPI in raspi-config
  install python libs: Pillow, RPi.GPIO, spidev
  should work without sudo
  
  library is at  Fibel / Code / e-paper-python3.7
  put driver folder in your code folder
  original PaperTTY lib is driver_it8951.py
  mine version is it8951.py
  
  here is example of using it:
  
  
  from PIL import Image, ImageDraw
import drivers.drivers_base as drivers_base
# import my version of lib with extra features
import drivers.it8951 as driver_it8951

# if you wanna use original PaperTTY lib change the line to import drivers.driver_it8951 as driver_it8951

# init communication with IT8951
driver=driver_it8951.IT8951()
driver.init(partial=True)

# get address of 0 page (first page of framebuffer)
img_addr=driver.img_addr

# get values for black and white
black = driver.black
white = driver.white

# get size of your screen
width = driver.width
height = driver.height

# this function convert page number to address of framebuffer
def pageList(img_addr,page):
    return img_addr+page*(2*driver.width*driver.height+1)

# load image with Pillow
filename = '' # please provide path to your file
image=Image.open(filename)
# and convert it to BW format
image=image.convert('1')

   
pageNumber = 0 # define page of frambuffer where to load the image
driver.load_image(0,0,image,img_addr=pageList(img_addr,pageNumber))

# display image from specified page of framebuffer (pageNumber)
driver.display_buffer_area(0,0,width,height,1,pageList(img_addr,pageNumber))

# you can use any function of Pillow lib to draw and print the text
# here is example of drawing simple line

image = Image.new('1',(image.width,image.height),white)
draw = ImageDraw.Draw(image)
draw.line((0,0,width,height),fill=black)

# load it to page 1 so we can keep previous loaded image
pageNumber = 1
driver.load_image(0,0,image,img_addr=pageList(img_addr,pageNumber))
driver.display_buffer_area(0,0,width,height,1,pageList(img_addr,pageNumber))
  
  
  use at your own risk

  should work from Fibel_V1 root dir
  
  
  in tests 5x5 seems the smallest chunk you can pass display_buffer_area

  Notes on the Assembly of the Fibel: The waveshare wm8960 "can operate at up to 5.5V, providing 1W per channel into 8 ohm loads". Varios speaker provide diffrent resistance, but slightly under or over the value seems to work fine aswell. The connector of the epaper hat seem just to work with the down side marked connector
  

  WARNING :: Do not mess too much with e-paper replugging in the IT8951 controller when controller is under power. You may brick the controller->IT8951 circuitry badly.
