Ebyte LoRa E22 per Arduino, esp32 o esp8266: configurazione – 3

di Renzo Mischianti · 29 Marzo 2022

Spread the love

La telemetria dei dati wireless LoRa o Long Range è una tecnologia introdotta da Semtech che opera a una frequenza inferiore degli NRF24L01 (433 MHz, 868 MHz o 916 MHz contro 2,4 GHz per NRF24L01) ma copre tre volte la distanza (da 4000 ma 10000 m).

Ora proviamo ad esaminare meglio come configurare il dispositivo LoRa Ebyte E22 UART basato sui moduli wireless SX1262/SX1268.

Ho creato questa libreria per gestire gli EBYTE E22 ma soprattutto per semplificare il processo di configurazione perché può essere molto noioso.

Se hai problemi di blocco del dispotivo, devi inserire una resistenza di pull-up da 4,7k o meglio collegarti al pin AUX del dispositivo.

Libreria

Puoi trovare la mia libreria qui.

And It’s available on Arduino IDE library manager.

EByte LoRa E22 E32 Arduino library manager

Per scaricare.

Clicca il bottone DOWNLOADS sull’angolo in alto a destra, rinomila la cartella decompressa LoRa_E22.

Controlla che la cartella LoRa_E22 contenga LoRa_E22.cpp e LoRa_E22.h.

posizione la cartella della libreria LoRa_E22 sulla tua cartella /libraries/.

Dovrai creare la sotto cartella librarues se è la tua prima libreria.

Schemi di connessione per la programmazione

Per l’utilizzo di base, abbiamo utilizzato una configurazione specifica per Arduino. Tuttavia, stai lavorando solo in “Modalità normale” in quella configurazione. Ora gestiremo solo i pin dinamici necessari (RX, TX) per semplificare il processo di programmazione e gli altri in modo statico.

Mode	M1	M0	Explanation
Normale	0	0	UART e il canale wireless sono aperti, la trasmissione trasparente è attiva (supporta la configurazione via etere tramite comando speciale)
Modalità WOR	0	1	Può essere impostato come trasmettitore WOR e ricevitore WOR
Modalità configurazione	1	0	Gli utenti possono accedere al registro tramite la porta seriale per controllare lo stato di funzionamento del modulo
Modalità Deep sleep	1	1	Sleep mode

Configurazione normale (trasparente)

Ebyte LoRa E32 E22 E220 Arduino UNO normal mode breadboard

M0	GND (Imposta modalità normale)
M1	GND (Imposta modalità normale)
TX	PIN 2 (PullUP 4,7KΩ)
RX	PIN 3 (PullUP 4,7KΩ & partitore di tensione)
AUX	Non connesso (PullUP 4,7KΩ)
VCC	3.3v/5v
GND	GND

e questa configurazione per Wemos D1 mini:

AUX	Non connesso (PullUP 4,7KΩ)
VCC	3.3v/5v
GND	GND

Cablaggio per la modalità di programmazione/sleep

Per configurarlo, è necessario impostare M0 su GND e M1 su HIGH (ricordarsi di utilizzare 3.3v).

Ma se colleghi tutti i pin, la libreria imposta in ALTO o BASSO i pin a secondo necessità senza problemi.

Per avere le informazioni corrette, aggiungo alcuni #define per cambiare il tipo di dispositivo (lo stesso #define gestisce più dispositivi, ne creo solo uno per tipo per semplicità).

LoRa E32 request configuration logic analyzer Arduino

To get the correct information, I add some #define to change the device type (same #define manage more other devices, I create only one for type for simplicity).

#define E22_22
#define E22_30

Puoi selezionarne solo uno. Il parametro modifica la costante di potenza di trasmissione come descritto nello schema di configurazione.

Allo stesso modo è possibile selezionare una frequenza di riferimento

#define FREQUENCY_433
#define FREQUENCY_170
#define FREQUENCY_470
#define FREQUENCY_868
#define FREQUENCY_915

Puoi sceglierne solo uno. Il parametro modifica le frequenze di riferimento solo a scopo di visualizzazione.

Imposta configurazione

Naturalmente, quando hai una configurazione che vuoi cambiarla per il tuo scopo, penso che tu possa ottenere la configurazione da un dispositivo, modificare ciò che vuoi e impostarla.

Ma nello sketch di esempio, aggiungo un set di configurazione commentato, puoi decommentare la configurazione che vuoi, e negli altri esempi in libreria, c’è un riferimento alla relativa configurazione da applicare.

Ricorda che il parametro saveType è fondamentale per mantenere le opzioni al riavvio del dispositivo, WRITE_CFG_PWR_DWN_LOSE naturalmente perderai le impostazioni con WRITE_CFG_PWR_DWN_SAVE non perderai le impostazioni.
