seread 0.1.8

Script to read serial port and store to file/influxdb

• Project seread

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

This code managed to read (in the past):

• ORTEC COUNTER (raw numbes)
• 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

** Input/Output files

INPUT

• ~/.seread.calib
• ~/.myservice_discover8086
• ~/.myservice_permanent8086
• ~/.influx_userpassdb
• ~/.sng2_udp
• script OUTPUT
• ~/serial_NG2_udp
• ~/serial_NG2_jso

** Options

• -i -influxyes [true|false] : send to influx on -i

** 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.

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

Example: #+BEGIN_SRC { "valuea0":{"a":0.21699,"b":-61.111}, "valuea1":{"a":0.1861328,"b":-40.2} } #+END_SRC

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.

*** Arduino-mode

**** 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

**** 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/

**** 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:

#+BEGIN_SRC lisp (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")

#+END_SRC

**** 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
