ESP32S3

i have a already old board here,
a copy of a OEM board, ( sure with original cpu 'ESP32S3 WROOM 1' N16R8)
but after initial problems enable LED ( solder point )
never problems, even in bigger projects using the 16MB PS FLASH and 8GB PS RAM all worked.
( but a friend got a other batch what had big problems using 'WiFi.h' and needed to send it back )

and the USB cable connected right side ( if WiFi antenna UP )
* backside labeled [COM] goes directly to ESP chip
* * left side port [USB] is from the added USB chip for use as HID...

documentation YD-ESP32-S3
but backside print different ( as a copy board of VCC-GND board )

YD-ESP32-S3
2022-v1.3

USB OTG (solder point)
[COM] [USB]

ESP32S3 Arduino IDE 2

in Ardunio IDE / File / Preferences /Additional Boards Manager URLs
use:

https://espressif.github.io/arduino-esp32/package_esp32_index.json
https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

when use Arduino IDE
* not need to press any buttons on esp32s3 for upload.
* for esp32s need press right button for every upload (to connect )
* for PICO xW need to press [bootsel] while connect USB cable only for the very first time and use special port

here use the Arduino default settings ( not use N16R8 features in that small code project )
with selected board: ESP32S3 Dev Module

1 Mloop

first test with that high speed cpu 240 MHz
is the time [sec] it needs to make 1 000 000 loops with counting
and add a 1 sec JOB ( later used to do Analog sampling / check web-page or mqtt in )
and add optional a N sec JOB
and add a 1 min JOB ( later used to do MQTT.. )

tests:

ESP32S3 N16R8 on Arduino IDE 2.3.4
___ loop1M dt : 0.26 // FOR 1Mloop only
___ loop1M dt : 0.47 // incl 1 sec / Nsec / 1min JOB

while you think that reflects the cpu speed in counting, wrong
a major factor is actually here what is the cpu doing inbetween the Arduino loop calls,
same board / cpu same functionality
but run under Micro Python or Circuit Python
might be slower as the Arduino UNO i tested 2013 with 4 .. 12 sec

begin combined project

now using the ESP32S3 for a project i started with PICO W ( under Arduino IDE 2 )
and make a code what allows to burn for both requires using compiler switches.

while usually you start with


#define useESP

#ifdef useESP
...
#else // do a PICO W thing

#endif

here is the Arduino IDE trick,
for all Arduino board have compiler switches already,
for ESP is only one:

#ifdef ESP32
...
#else // do a PICO W thing

#endif

this is working as soon you select a Arduino board type ESP..
( it does not talk with the board "WHO ARE YOU" or need one at compile time )

MQTT TLS

actually why i am here using Arduino IDE
for 2 years i fight with Circuit Python and Micro Python
about the use of MQTT like umqtt/simple.py in Arduino PubSubClient
but talk to HIVEMQ TLS directly ( having a free account there with 100 devices and 10GB / month bandwidth )
now in Arduino IDE i got PICO W running and using ESP32S3
even improved coding without external library ( or even cert's )

#include <WiFi.h>
#include <WiFiClientSecure.h>
#include <MQTT.h>
wifiClient.setInsecure(); // secure TLS but not check server cert

so the code for: with and without TLS ( local or cloud broker )
and for 2 devices PICO W and ESP32S3

is heavy use of that compiler switches.

later i try same with a old ESP32s :
NODEMCU32s_HIVEMQ_ino

but in this combined project use again a switch

//#define usePICOW2 // _________________________________________________ enable THIS to burn PICO2W D217

//#define useESP32s // _________________________________________________ for Node32s boards.. i use board: NodeMCU-32S

what selects different / name / IP / TOPIC / info texts /
same like when use the new PICO 2W
not because any function is different, just to have
* different info
* and can run 4 different boards
* from one code
* at same time.

RPI4 & RPI3

i use RPI4 as Mosquitto broker and local NR ( as in a 66$telemetry setup but also for development)
add i use RPI3 as backup / file-server / GIT master
check on

RPI4 setup for Mosquitto and Node-Red and Arduino

RPI3 and Open Media Vault add GIT

HOME NodeRed

we have a 'local' project with prepared
4 devices sending mqtt to local RPI Mosquitto and NodeRed
that NodeRed sends a copy of TOPIC
*/data
*/log
also to cloud broker like HIVEMQ

now imagine you are in the headquarter and want see that data? ( and also from other SITEs )

-a- need a server ( cloud or local ) / a RPI4 again is OK /

-b- install NodeRed ( add dashboard & sqlite ) / no Mosquitto /

-c- copy the project NR flow ( same like have at the project RPI )
* delete REMOTE node ( we are remote already, not need to copy anywhere else )
* disable OPERATION flow ( even if wanted REMOTE OPERATION, it would only work if local NR would bridge the commands )
* from OS setup PATH for sqlite DB
* change MQTT from [192.168.1.104] local RPI Mosquitto to the cloud broker 'xxx.hivemq.cloud' ( using TLS 8883 ) add user password
* fill project database like local NR ( and also TOPICs from other SITE's )

6$telemetry

above setup
* HOME (headquarter) NodeRed
* cloud broker like HIVEMQ

and a local installation: lets call that:

66$telemetry

* different devices ( and different sensors ) talk to
* local RPI with Mosquitto and NodeRed ( and old Arduino IDE with source code of the project devices )

BUT we have additionally the option
lets say for a very small project ( like battery monitoring on your boat )
you not need there a RPI / Mosquitto / NodeRed

can use a board and talk to REMOTE cloud broker directly
that is called 6$telemetry
here some old design drawings:
* MultiSite_Telemetry
* MINI_site ( 66$ )
* MICRO_site (6$)

to test THAT '6$ telemetry' setup:

-a- on HOME NodeRed
define that new project
mexico
MEX/D220/data
ESP32S3 with remote broker enabled

mod in flow:
'SAVE to DB'
add SAVE
/data

and flow:
'LOG_DB'
/log

not forget to later check if
* HIST-TREND and
* LOG LIST
for this new entry / project / works.

-b- use a ESP32S3
burn latest project with following settings in 'secrets.h'


#define useREMOTE_BROKER_HIVEMQ // deselect by // mexico test

and give LINK / USER / PASSWORD

and overwrite default settings TOPIC for ESP32S3

#else // ESP32S3
#define sTOPIC "MEX/D220/status" // mexico
#define bTOPIC "MEX/D220/log"
#define dTOPIC "MEX/D220/data"
#define rTOPIC "MEX/D220/set" //'LED TOGGLE' R0 R1 R2 R3
#define fTOPIC "MEX/D220/fdata" //___________ 1 sec reads A0
#define MQTT_CLIENTID "MEX D220"
#define MQTT_STATUS "ESP32S3 ArduinoIDE"
#endif

also overwrite ESP32S3 default
fixIP .216 with .220
( we have to test it at home first so it should not conflict with the other esp32s3 )
save to project_path: /BOARDS/ESP32S3/MEXICO/ & UPLOAD

find web-page

small steps

more detail work:
now that page has a HTML title and header what is already dynamic, but just board dependent
better is to have a header what includes a project text

now also add the above linked LOGIN SYSTEM

here even with LEGAL note

and the /LOG also show the BootLog

add a idea for NR
make a DAY REPORT ( csv style )
as we have MULTI PROJECT need to make N reports at midnight
from a list of projects ( read TOPIC from project list )

idea is to overwrite themselves to not eat up storage double,
but what to do with it?
? a email daily sending the files from RPI to ?
? a option to copy the files remotely ( manually ) ? when needed
? a dashboard operation to trigger that ( possibly for a select-able date )

CODE at GIT

now here have the link to the
GIT repository
latest:
Arduino IDE project:

PICO2_ESP_WIFI_newMQTT_WEBPAGE_INA_ACS_ADS_V271

features:
* BOARDS
* * ESP32S

* * Link list and About list

* MQTT
* * local RPI Mosquitto [192.168.1.104] (no TLS )

for all that option and more see 'secrets.h'


// file: secrets.h
#define MY_PROJECT "SITE: _______, DEVICE: D___" // D216 is IP .216 and D216 in topic..( unique for ONE site / LAN )

#define use4RELAY

// I2S: currently can only select 1 INA at default x40
//#define use_INA_219
//#define use_INA_260

// ACS and ADS overwrite A0 input so also can NOT use both
//#define use_ADS1115 // at default x48

//#define useACSxxx
#ifdef useACSxxx
#define useACS712
//#define useACS758
#endif

//#define usePICOW2 // _________________________________________________ enable THIS to burn PICO2W D217

//#define useESP32s // _________________________________________________ for Node32s boards.. i use board: NodeMCU-32S

#define OPERATIONPW "admin"

// MQTT select remote broker TLS or local broker NO TLS // select only ONE
//#define useREMOTE_BROKER_HIVEMQ // deselect by //

also at GIT:

* NodeRed flow ( for local RPI4 Mosquitto and NodeRed installation )
with dashboard:
* * Project Database ( sqlite CRUD app ) for MULTI SITE / DEVICE drop-down selector switch in #
* * CURRENT TREND #
* * HIST LIST
