seread 0.2.14

Script to read serial port and store to file/influxdb

Project seread

IN CONSTRUCTION NOW - VERSION 0.1.23+ now may work

the first goal is to read serial ports and save the data to file and influxdb

TL;DR

Try ./bin_seread -D /dev/ttyACM0 -t 2,10 -c word from git directory or

seread -D /dev/ttyACM0 -t 2,10 -c word from pypi install. Supposing, you have your device on /dev/ttyACM0

What it did up to now

This code managed to read (in the past):

• ORTEC COUNTER (raw numbes, using script)
• arduino analog pins A0-An (json going out from arduino)
• arduino DHT sensor (with json output coded)
• arduino I2C pressure sensor
• arduino NTC temperature sensors (preprogrammed)

Installation

The project still develops, changes can be made anytime. The actual dependencies can be installed by running ./pipall.py.

The code should be run by seread

Basic usage

Parameter -t

The original aim is to read serial in Short period (like 1s or 2s for DHT) and write to TXT files. Then every Long period (like 60s, 120s) it writes to influxdb(s) and sends UDP packets (to root acquisition running to display counters)

seread -D /dev/ttyACM0 -t 2,10 -c word

Parameter -D or -l

Device can be defined by the ttyXXX or by location. See what is detected on seread.

seread.calib

Calibration after readout

It is possible to make a calibration after reading the serial values in json. Check the file ~/.seread.calib

Example:

{
"valuea0":{"a":0.21699,"b":-61.111},
"valuea1":{"a":0.1861328,"b":-40.2}
}

Pay attention to commas and double quotes. valuea0 is the same name of the analog value exctracted from the arduino, a b are linear coefficients.

sereaddiscover8086

This contains IP - one per line - of PCs with influxdb running The user, pass, database is in the file ~/.influx_userpassdb

udpout

lines with IP:PORT or without PORT, then 8080 is assumed. The will be UDP packet sent to IP:PORT (every long period)

script

this runs one line at a time and repeats the last line forever. The example starts the ORTEC counter

Options

• -t two time periods, read,writeinflux: -t time1,time2
• -i -influxyes [true|false] : send to influx if -i is present. Sending will happen on time2: -t time1,time2

More functions: (in construction)

8099 port server

This is Vadim's function. Information obtained on this port will store data in influxdb. Vacuum mainly. For the moment, there are several interpreters:

1. influxme

   echo 'influxme [{"measurement":"geo","fields":{"longitude":15.0,"latitude":50.0}}]'

   for ((i=0;i<10;i++)); do echo 'influxme [{"measurement":"geo","fields":{"longitude":15.0,"latitude":50.$i}}]' ; done

2. influxmegeo

   echo influxmegeo geo 14.28 49.86 | nc 127.0.0.1 8099

3. ptz

   May need to install some stuff: sudo apt-get install python3-smbus

   echo ptz pan +5 | nc 127.0.0.1 8099 echo ptz tilt -5 | nc 127.0.0.1 8099

APPENDIX

Adding dialout group to be able to work with USB

sudo usermod -a -G dialout $USER then either reboot of logout/login or try `newgrp dialout` in terminal.

Arduino-mode

1. Arduino programming remarks

   Different types need different settings in the original IDE.

   • Chineese NANO
     • Tools/ArduinoNano/ATmega328P(old)/ttyUSB0
   • UNO with shield
     • Tools/ArduinoUNO/__/ACM0 with programmer AVRISM mkII

2. Straight installer in emacs is fast

   • go to (https://github.com/raxod502/straight.el and prepend

   the code to the ~/.emacs to use straight-use-package

   • say M-x straight-use-package arduino-mode
   • install auto-minor-mode
   • install somehow arduino-cli from https://github.com/arduino/arduino-cli) and [package](https://arduino.github.io/arduino-cli/installation/

3. emacs setting

   • copy arduino-cli.el file from

   https://github.com/motform/arduino-cli-mode to ~/.emacs.d/lisp/ and add (add-to-list 'load-path "~/.emacs.d/lisp/") and (load "arduino-cli.el") to ~/.emacs.

   BUT as now, I cannot compile, as --fqbn is needed and not given automatically.

   • IN EMACS say M-x arduino-cli-mode

   The ~/.emacs contents:

   (defvar bootstrap-version)
   (let ((bootstrap-file
          (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
         (bootstrap-version 5))
     (unless (file-exists-p bootstrap-file)
       (with-current-buffer
           (url-retrieve-synchronously
            "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
            'silent 'inhibit-cookies)
         (goto-char (point-max))
         (eval-print-last-sexp)))
     (load bootstrap-file nil 'nomessage))
   ;;
   ;;
   (straight-use-package 'arduino-mode)
   (add-to-list 'auto-minor-mode-alist '("\\.ino\\'" . arduino-cli-mode))
   ;;
   (add-to-list 'load-path "~/.emacs.d/lisp/")
   (load "arduino-cli.el")
   

4. Arduino-cli commandline

   • arduino-cli config init

   • arduino-cli core update-index

   • arduino-cli board list

   • arduino-cli core install arduino:samd

   • arduino-cli core install arduino:avr

   • arduino-cli core list

   • arduino-cli core listall

   • arduino-cli core --fqbn arduino:avr:diecimila test.ino

   • arduino-cli compile 20200411-logoled-ser1sd0.ino --fqbn arduino:avr:nano

   and arduino-cli upload --fqbn arduino:avr:nano -i 20200411-logoled-ser1sd0.ino.arduino.avr.nano.hex -p /dev/ttyUSB0 should work
