Fout in h bestand?

[Cees Profiel Privébericht]

Beste mensen,

Sinds kort ben ik met arduino begonnen. Ik heb een startset gekocht en een aantal aanvullingen hierop. Met plezier de projectjes gemaakt en tot een goed einde gebracht. Vervolgen een smarthome set gekocht, met een esp32 plus bordje. Als ik de schets in het bordje wil laden dan krijg ik onderstaande melding. Het is mij onduidelijk hoe ik hier mee om moet gaan als beginner. Zouden jullie mij op weg willen helpen om dit probleem te verhelpen?

Cees dat is vrij normaal hoor dat als je direct een library aanroept, en er staat iets in zoals in jouw geval een wire die naar een variabele zoekt i2c_t, als eerste even zoeken naar een juiste librarie (wire) en dan ook kijken of deze voor jouw esp werkt want de pinnen zitten vaak op een andere plek.

[ThHe Profiel Privébericht]

Het lezen van een foutmelding is soms lastig.
Bij een foutmelding van een compiler geldt "los de problemen op in de volgorde zoals zij zich aandienen".
Dus alleen de eerste foutmelding oplossen en de rest komt later.

Melding: In file included from /home/cees/Bureaublad/keyestudio09/3. Arduino Tutorials/arduino Code/pj13_2_IoT_smart_home/pj13_2_IoT_smart_home.ino:16:
/home/cees/Bureaublad/sketch/libraries/Wire/src/Wire.h:44:5: error: 'i2c_t' does not name a type; did you mean 'ino_t'?
i2c_t * i2c;
^~~~~
In de eerste regel staat de code waarmee de compiler bezig is in dit geval: "pj13_2_IoT_smart_home.ino"
en dat de fout optreedt regel 16.
Op internet de code opgezocht staat op regel 16 inderdaad de include van Wire.h waarin de de foutmelding wordt gemeld.
De wire.h file staat bij jouw in de map libraries/Wire/src maar die versie met de fout op regel 44 kan ik niet vinden.
Twee mogelijkheden:
1. geef het bestand wire.h en wire.cpp een andere tijdelijke naam bv xwire.h en xwire.cpp en dan proberen te compileren.
(misschien is de versie die met arduino standaard wordt meegeleverd degene die je moet hebben.)
2. plaatst de text van wire.h op het forum.

[Cees Profiel Privébericht]

Naar aanleiding van het bericht van Shooter op zoek gegaan naar een ander wire bestand. Ik heb het niet kunnen vinden. Mogelijk speelt mijn onbekendheid met de materie hierin een rol. In de bibliotheek van de Arduino IDE stonden wel bestanden welke richting wire wezen, echter gaven deze weer andere problemen bij gebruik hiervan. Is er iemand die het smarthome KS5009 setje van keyestudio, met alle bijgeleverde schetsen en libraryś aan de praat heeft gekregen?

Een zich ten einde geen raad meer wetende beginner en met vriendelijke groet,

Cees

[Cees Profiel Privébericht]

Beste mensen, ik heb de suggestie van ThHe over genomen en uitgevoerd. Als ik de naam van het wire bestand verander, kan er geen wire bestand gevonden worden door de IDE. Er is er dus maar één beschikbaar op mijn computer. Zoals aanbevolen voeg ik het bestand hier bij.

Voor welk bord compileer je het programma? Ik denk dat i2c_t alleen bekend is in de ESP wereld hetgeen dan de vraag brengt of je voor het juiste board compileert. Je kunt een programma dat specifiek geschreven is voor een ESP32 of dat gebruik maakt van ESP specifieke bibliotheken niet compileren voor b.v. een Uno.

Laat je programma hier zien; vergeet niet om code tags te gebruiken

SterretjeToo,
Het bordje dat gebruikt wordt is een Keyestudio ESP32 plus development board. Artikelnummer KS5016. Op het bordje zijn drie aansluitingen bij elkaar met de benaming bus I2C. Hierop is de RFID en het LCD1602 display op aangesloten. Als IDE gebruik ik arduino 2.2.1. Besturingssysteem is linux mint. Met windows krijg ik overgens ook de foutmeldingen. Het board dat geselecteerd is, is ESP32 Dev module. In de handleiding van het setje wordt hier naar verwezen.

Ik ben geen ESP32 gebruiker. De eerste vraag is wat je board url is in file → preferences.

https://dl.espressif.com/dl/package_esp32_index.json zoals gevonden op via de jeyesstudio site (https://www.dropbox.com/sh/drzeuimi0a4a ... tracking=1)

of iets anders. Op mijn systeem staat deze op https://espressif.github.io/arduino-esp32/package_esp32_index.json

Ik kon twee bibliotheken niet vinden (IDE / github)
1) xht11
2) ESP32Tone

Als ik alles eruit sloop gerelateerd aan die bibliotheken en ook de '#include <analogWrite.h>' eruit sloop compileert het op mijn system. Ik moest de laatste eruit slopen omdat, na het installeren van die bibliotheek, de linker een conflict gaf.

Kun je a.u.b. aangeven waar ik die kan vinden. Kun je ook aangeven welke LiquidCrystal_I2C bibliotheek je gebruikt; er zijn er teveel en voor degene die ik geinstalleerd hebt krijg ik een melding dat deze mogelijk niet compatibel is.

Nu is dit niet een juiste test; maar je LiquidCrystal_I2C zou de foutmelding moeten reproduceren vermoed ik.

Laatste opmerking
Ik weet niet of de ssid en password je echte gegevens zijn; indien ja, wees zo verstandig die in de toekomst niet meer te publiceren. Verander ze naar een paar sterretjes of zo.

Getest sketch die op mijn system (Windows 10, IDE 1.8.19 portable install), compileert

Als eerste wil ik melden dat ik alles wat met arduino te maken heeft van mijn computer heb verwijderd. Hierna stap voor stap de arduino IDE en het smarthome, volgens de handleiding opnieuw geinstaleerd. De url die ik gebruik, is die zoals genoemd in de handleiding; https://dl.espressif.com/dl/package_esp32_index.json.

Met deze url, https://fs.keyestudio.com/KS5009, kom je in een dropbox terecht waar het complete pakket is op te halen, ook de bibliotheken en de schetsen.

Ik gebruik de LiquidCrystal_I2C bibliotheek welke in het pakket zit. De foutmelding krijg ik ook, maar deze is weg te halen door in de properties van de bibliotheek achter de avr melding “, esp32” te plaatsen.

De issd en wachtwoord zijn van de maker van de schets, dus geen probleem. Maar bedankt voor de waarschuwing.

Als ik nu de originele schets compileer dan krijg ik ook de melding dat er een probleem is met de analogeWrite.h, hiermee zitten we nu dus op een lijn.

Als ik de aangepaste schets compileer dan gaat dit foutloos. Na het inladen krijg ik het ip adres op het display en kan ik met het tablet contact maken met het smarthome. De led, het raam en de ventilator kan ik bedienen. Alle overige projecten reageren niet.

Ik ben heel blij met de vorderingen tot nog toe. Het geeft weer moed om verder te gaan.

Met de hoop dat de analogeWrit de laatste hobbel is en dat deze kan worden opgelost, en met vriendelijke groet,

Cees

[Cees Profiel Privébericht]

Op internet nog eens aan het zoeken gegaan naar commentaren/reviews over het pakket. Ik ben er één tegengekomen die het pakket beoordeelt.

De recensent heeft de losse projecten van het pakket uit geprobeerd, en daar werken een aantal niet van. Dat was bij mij ook zo. Het lijkt er op dat de schetsen wat slordig gemaakt zijn. Er ontbreken her en der wat tekens zoals haken, of puntkomma's. Na veel zoekwerk, op één na, de projecten werkend gekregen. Ook de recensent kreeg dit project niet werkend.

Omdat de aangepaste schets van Serretje Too wel werkte heb ik de originele schets weer uitgeprobeerd zoals ik in het vorige bericht heb aangegeven. De analogeWrite.h geeft dan problemen. Deze heb ik in de schets geblokkeerd. De schets lade zonder problemen op het bordje, en alle functies welke beschikbaar zijn in de wifi app gaan op commando werken.

Het resultaat is dat het smarthome project werkend is geworden met jullie hulp. Ik dank iedereen die mij met raad en daad hebben bij gestaan.

Met vriendelijke groet,

Cees.
