I have a 1.2" 7-segment led display. With the HT16K33 controller. I have made a clock with this display on Arduino, which connects to the internet and gets the time from the "pool.ntp.org" server.
I want to do the same but using B4R, I have hardly seen examples and I am very lost. At the moment what I have in B4R connects to the server "time.nist.gov" to get the time. I don't know how I could use the Arduino libraries in B4R to show the time on the 7-segment display with the HT16K33 controller.
B4X:
#include <WiFi.h>
#include "time.h"
#include "HT16K33.h"
HT16K33 seg(0x70);
const char* ssid = "*****";
const char* password = "*****";
const char* ntpServer = "pool.ntp.org";
const long gmtOffset_sec = 3600;
const int daylightOffset_sec = 3600;
void printLocalTime()
{
struct tm timeinfo;
if(!getLocalTime(&timeinfo)){
Serial.println("Fallo en la obtencíon de la hora");
return;
}
Serial.println(&timeinfo, "%A, %B %d %Y %H:%M:%S");
//Averiguar como transformar H y M para mostrarlo en displayTime
char hora[3];
strftime(hora,3, "%H",&timeinfo);
char minuto[3];
strftime(minuto,3, "%M",&timeinfo);
Serial.println(hora);
Serial.println(minuto);
int ihora=String(hora).toInt();
int iminuto=String(minuto).toInt();
seg.displayTime(ihora,iminuto,true,true);
// seg.displayTime(%H,%M,true,false);
}
void setup()
{
Serial.begin(115200);
seg.begin();
//Wire.setClock(100000);
seg.displayOn();
seg.setDigits(4);
//Conectar al wifi
Serial.printf("Conectando %s ", ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println(" Conectado");
//Iniciar y obtener la hora
configTime(gmtOffset_sec, daylightOffset_sec, ntpServer);
printLocalTime();
//Desconectar el Wifi si no es necesario
WiFi.disconnect(true);
WiFi.mode(WIFI_OFF);
}
void loop()
{
delay(1000);
printLocalTime();
}
