pigropico – PiGro for Raspberry Pi Pico

Pico / PicoW (rp2040)

Pico2 W (rp2350)

Waveshare Pico-ResTouch-LCD-3.5

PiGro – horticulture easy

(Pico2_W)

(Pico_w)

connect:

• connect the Pico to a Linux machine (USB) / serial port

• in one terminal (ttyACM0 depending on Linux distribution)

  minicom -o -D /dev/ttyACM0

• in another terminal

  pigsh 0

• to connect via serial (/dev/ttyS0)

  spigsh 0

• to connect via web/api

  pigroshka 192.168.171.2 (Pico 2)

  pigroshka YOUR-PIGRO-IP (Pico W)

remember to prepend 'set' in 'pigroshka'

set pwm0 10

news:

• pigropico2w.uf2 Pico2_W

• syslog for Pico2

• new icons in web ui from https://www.svgrepo.com/

• PiGro for Pico2 - pico2_pigropicow.uf2 (rp2350)

• Pico2 webserver (USB) http://192.168.171.2 or https://192.168.171.2

• PiGro Pico2 only fixed POSIX time string

• (non-range) time in rules: time8, time2:12PM, time22

  addrule time5 -> pwm1 60

  will create a rule, executed once, at 5 (AM)

  save your rules when done

• remember: time values never contain a ' ' space character!

  always: 'timeHH:MMxM-HH:MMxM'

  xM is AM/PM

  now, all except the first HH value can be omitted

• WiFi country code in status

• GUI reworked

• pigsh bash script added (minicom , usb)

• network memory leak fixed (http server)

• virtual keyboard improved

• sensors: aht15 / hih71

• editor fixed

• press 'Rules Selector' (text) to create a new (empty) rule

new commands:

netip get WiFi network ip address

usbip get USB network ip address

tlog LALA to write 'LALA' to the syslog server (via TCP)

posixtime CEST-1CET,M3.5.0/2:00:00,M10.5.0/3:00:00 set the timestring (Pico2)

time 13:14:15 set time (24h only)

defaults to 'Europe/Berlin'

'tz_list' contains a list of names / posix time strings (pcodes)

`grep Shanghai tz_list` -> `"Asia/Shanghai","CST-8"`

`grep Belgrade tz_list` -> `"Europe/Belgrade","CET-1CEST,M3.5.0,M10.5.0/3"`

`grep New_York tz_list` -> `"America/New_York","EST5EDT,M3.2.0,M11.1.0"`

`grep Kamchatka tz_list` -> `"Asia/Kamchatka","<+12>-12"`

to adjust your time to New York (in pigsh/spigsh) 

`posixtime EST5EDT,M3.2.0,M11.1.0`

then -> `save` to reset and save

tz_list was generated with https://github.com/nayarsystems/posix_tz_db

syslog LALA to write 'LALA' to the syslog server (via UDP)

tlog LALA to write 'LALA' to the syslog server (via TCP)

set_country XX set the wifi country code (to 'WORLDWIDE')

(check the end of this document for the country codes)

liru list rules (in RAM, stat shows the rules in 'SRAM')

crules check / test all rules

crule 7 check / test rule number 7

hostname pigro set hostname to 'pigro'

ssid0/cred0 set ssid and credentials (wifi)

ssid1/cred1 same but for second (alternate) network

stat_bu 3 print status for save backup slot #3 (0-31, rotating)

to see the variant (rp2350/rp2040) and the pins you can use 'picotool'

picotool info pigropicow.uf2

flash

sudo picotool load ./pigropicow.uf2 -x --bus 1 --address XX

Or: just drag'n'drop pigropicow.uf2 / pico2_pigropicow.uf2 to your drive

usage

Rules

WiFi (not) connected

Configure

Rotate display

Save

PicoW:

• select WiFi network, enter credentials, CONNECT0, wait...
• after a successfull connection a 'SAVE0' button appears
• press it to save and restart PiGro
• PiGro web client should be available at 'http://pigropicow/' in your network

country codes (from the driver)

(from pico/pico-sdk/lib/cyw43-driver/src/cyw43_country.h)

WORLDWIDE ('XX') AUSTRALIA ('AU') AUSTRIA ('AT') BELGIUM ('BE') BRAZIL ('BR') CANADA ('CA') CHILE ('CL') CHINA ('CN') COLOMBIA ('CO') CZECH_REPUBLIC ('CZ') DENMARK ('DK') ESTONIA ('EE') FINLAND ('FI') FRANCE ('FR') GERMANY ('DE') GREECE ('GR') HONG_KONG ('HK') HUNGARY ('HU') ICELAND ('IS') INDIA ('IN') ISRAEL ('IL') ITALY ('IT') JAPAN ('JP') KENYA ('KE') LATVIA ('LV') LIECHTENSTEIN ('LI') LITHUANIA ('LT') LUXEMBOURG ('LU') MALAYSIA ('MY') MALTA ('MT') MEXICO ('MX') NETHERLANDS ('NL') NEW_ZEALAND ('NZ') NIGERIA ('NG') NORWAY ('NO') PERU ('PE') PHILIPPINES ('PH') POLAND ('PL') PORTUGAL ('PT') SINGAPORE ('SG') SLOVAKIA ('SK') SLOVENIA ('SI') SOUTH_AFRICA ('ZA') SOUTH_KOREA ('KR') SPAIN ('ES') SWEDEN ('SE') SWITZERLAND ('CH') TAIWAN ('TW') THAILAND ('TH') TURKEY ('TR') UK ('GB') USA ('US')

configure sntp:

• sudo nano /etc/ntp.conf for usb network (network/ip fixed)

  restrict 192.168.171.0 mask 255.255.255.0
  restrict 192.168.171.1 
  broadcast 192.168.171.255
  

• for a wireless network at 192.168.2.0/24 (or whatever you have)

  restrict 192.168.2.0 mask 255.255.255.0
  restrict 192.168.2.1 
  broadcast 192.168.2.255
  

• restart ntp service and check status

• sudo systemctl restart ntp

• sudo systemctl status ntp

configure syslog remote logging:

• create dir '/var/log/remote'and set owner/rights so it's accessible by syslog
• ubuntu:

sudo mkdir /var/log/remote
sudo chown -R syslog:adm /var/log/remote
sudo chmod 755 /var/log/remote

• install rsyslog sudo apt install rsyslog

• edit '/etc/rsyslog.conf' sudo nano /etc/rsyslog.conf

• enable tcp/udp logging by removing the prepending hashes '#' at module and input

# provides UDP syslog reception
module(load="imudp")
input(type="imudp" port="514")

# provides TCP syslog reception
module(load="imtcp")
input(type="imtcp" port="514")

• copy this snippet to the end of your '/etc/rsyslog.conf'

$template remote, "/var/log/remote/%HOSTNAME%.log"
if ($fromhost-ip != "127.0.0.1" ) then -?remote\n
& stop

• restart rsyslog sudo systemctl restart rsyslog
• and do a status check sudo systemctl status rsyslog
• in a terminal tail -n50 -F /var/log/remote/pigropicow.log (or whatever your hostname is)
