To start

python3 app.py 

IO calibration

• Use the RAW.py and paste into google sheets and download as a csv
• Use any text editor to open the csv as csv format as below. (visual-code will work)
• Use https://www.convertcsv.com/csv-to-json.htm and option CSV To Json Column Array
• Add the json file in /data/rubix-wires/io-calibration.json

UI1, UI2, UI1_MA
0.1, 0.1, 1
0.2, 0.3, 10
0.4, 0.4, null

Installation

• bash setup.bash

In details

https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/installation-on-ubuntu

• sudo apt-get update
• sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus python3-pip virtualenv -y
• pip install -U pip setuptools wheel
• cd bb-py-rest
• rm -r venv // remove virtual env, if exist
• virtualenv -p python3 venv // creating virtual env with python3
• source /home/debian/bbb-py-rest/venv/bin/activate // activating virtual env
• pip3 install -r requirements.txt // installing the packages for this project
• deactivate // deactivate current environment

Systemd Service

See status

sudo systemctl status nubeio-bbio.service
sudo systemctl status nubeio-enable-uart-pins.timer

Delete UART service files

sudo rm /lib/systemd/system/nubeio-enable-uart-pins.service
sudo rm /lib/systemd/system/nubeio-enable-uart-pins.timer

Disable UART service

sudo systemctl disable nubeio-enable-uart-pins.timer

Other Systemd Commands

• sudo systemctl stop nubeio-bbio.service
• sudo systemctl status nubeio-bbio.service
• sudo journalctl -f -u nubeio-bbio.service

Note: Version 1.4 of the Nube iO Edge Controller does not need the UART pins enabled and doing so conflicts with the pins for R1.

For testing

Comment out all the Adafruit_BBIO libs & uncomment the random values as below val = random.uniform(0, 1) # for testing

@app.route('/api/' + api_ver + '/read/' + ui + '/<io_num>', methods=['GET'])
def read_ai(io_num=None):
    gpio = analog_in(io_num)
    if gpio == -1:
        return jsonify({'1_state': "unknownType", '2_ioNum': io_num, '3_gpio': gpio, '4_val': 'null',
                        "5_msg": analogInTypes}), http_error
    else:
        # val = ADC.read(gpio)
        val = random.uniform(0, 1)  # for testing
        return jsonify({'1_state': "readOk", '2_ioNum': io_num, '3_gpio': gpio, '4_val': val,
                        '5_msg': 'read value ok'}), http_success

Block port 5000

In ip tables -A is to add and -D is to delete an entry

// only allow localhost access to port 5000
sudo iptables -A INPUT -p tcp -s localhost --dport 5000 -j ACCEPT
// drop all other hosts
sudo  iptables -A INPUT -p tcp --dport 5000 -j DROP
// then save the tables
!!! Not tested
https://upcloud.com/community/tutorials/configure-iptables-centos/

// to remove a rule
sudo iptables -D INPUT -p tcp --dport 5000 -j DROP

API for the GPIO

LoRa Connect Reset

This api will let you reset the power on the lora connect

// write the lora connect off
localhost:5000/api/1.1/write/do/lc/0/16

IO_TYPES ui, uo, di, do

// read /read/IO_TYPE/IO_Number // read all IOs as per type. like /read/all/ui /read/all/IO_TYPE

#### Read a UI as a DI (jumper needs to be set to 10K)
off/open = around 0.9 vdc
on/closed = around 0.1 vdc

### read all

// read all DIs http://0.0.0.0:5000/api/1.1/read/all/di // read all AIs http://0.0.0.0:5000/api/1.1/read/all/ai

#### UOs
https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/pwm

UOs 0 = 12vdc and 100 = 0vdc (Yes its backwards) <io_num>// uo/uo1/22/16 the priority (pri) is not supported yet but it's there for future use if needed http://0.0.0.0:5000/api/1.1/write/uo/uo1/100/16 // this returns the values that was stored in the DB (So not reading the actual pin value)

#### DOs
https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/gpio

/<io_num>// the priority (pri) is not supported yet but it's there for future use if needed DOs true for high false for low http://0.0.0.0:5000/api/1.1/write/do/do1/true/16

#### UIs
https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/adc

UIs will return a float between 0 and 1 http://0.0.0.0:5000/api/1.1/read/ui/ui1

#### DIs
https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/gpio

DIs will return a int either 0 and 1 (0 is on 1 is off) http://0.0.0.0:5000/api/1.1/read/di/di1

## Cloning eMMc image to microSD card as a Flasher.
* Boot off beaglebone on eMMc you wish to clone.
* Insert a blank FAT formatted microSD card at least 4GB.
* Login to your beaglebone and run the scripts
```bash
cd /opt/scripts/tools/eMMC
sudo ./beaglebone-black-make-microSD-flasher-from-eMMC.sh

• Once finish, reboot and boot off the beaglebone using the microSD card as an image flasher
