Hardware interface for DAUM Ergobike 8008 TRS

ergoFACE

Hardware interface for DAUM Ergobike 8008 TRS change for ATOM

first idea 22.12.2018; Michael Weinzinger

Overview

• A hardware + software interface ("ergoFACE") is going to be developed, which allows a mobile device (smartphone, tablet) to interact with a DAUM Ergobike 8008 TRS ("DAUM").

• The innitial idea is to be able to replace the standard cockpit of the DAUM with this solution (ergoFACE + mobile device).

• This can be achievend by plugging in the ergoFACE with the standard signal cable (4-wire cable) from the cockpit, or even complete disassembly of the cockpit unit and replace it permanent with a mobild device.

Aims

• Interaction between mobile device and DAUM
  • Capture the ACTUAL values from the DAUM on a mobile device
  • Send a SET POINT value from the mobile device to the DAUM
• Web server as gateway
• Saving the SET POINT and ACTUAL values as a training session
• Create SET POINT values for workouts
  • manually in an editor
  • convert recorded workouts / ACTUAL 2 SET POINT
• Selection of workouts
  • Manual SET POINT workout
    • WATT
    • Pitch/Climb
    • Heartrate
• Integration of additional external sensors
  • Bluetooth heart rate sensor
• Share the training sessions with social networks

Usage

ERG Mode with RS232 using BLE GATT Server to notify speed, cadence and power

• clone repository
• install requirements - see requirements.txt
• copy ergoFACE.service from lib\systemd\system to your local system

sudo chmod 644 /lib/systemd/system/ergoFACE.service

• configure

sudo systemctl daemon-reload
 sudo systemctl enable ergoFACE.service

• reboot

sudo reboot

• check status of service

sudo systemctl status ergoFACE.service

ergoface's Issues

watt.py - error handling of user input in module load

check the input for selection of yaml (watt file) if it is in the range of index to avoid error.

watt.py - split watt program into micro programs for use in conditions and state transitions

watt.py is too big, it must be splittet into the functional micro programs needed for the statemachine

watt.py - maximum recursion depth exceeded while calling a Python object

after 20+ simulated training autostarts, this error:
maximum recursion depth exceeded while calling a Python object

watt.py - sequence of watt yaml files not correct

looks like the sequence is backwards in test2.yaml
but this is not reproducible on other files

play intro sound at initialization of ergoFACE

• breadboard setup
• sound.py
• melody or sound in Hz and duration
• implementation in code

watt.py - sequence of item listing is not sorted

manual watt modus

implement a manual watt modus.
Idea - reuse the existing watt.py and yaml

create a manual.yaml file with only one seq:

Prog:
  Seq1:
    Name: Manual watt 
    Description: Manual Watt training
    Watt: 25
    Duration: 3600

Logging of training data

log the parameters for each training session in a yaml, csv or tcx file format

• session name
• program name
  • timestamp
  • watt
  • RPM

central config and parameters to conf.yaml

e.g.: in watt.py - dirName is a parameter, that has to be kept in a central place
