▷ Especificaciones del módulo ESP32

Imagen
⭐⭐⭐⭐⭐ Especificaciones del módulo #ESP32 ✅   Módulo ESP32 (ESP-WROOM-32): ✅   Módulo ESP32 (HUZZAH32): El #HUZZAH32 es módulo de desarrollo basado en #ESP32, hecha con el módulo oficial WROOM32. Este hardware contiene: convertidor USB a serie incorporado, reinicio automático del cargador de arranque, cargador de iones de litio / polímero, y casi todos los GPIO que sacaste para que puedas usarlo con cualquiera de nuestras alas de plumas. El ESP32 es una actualización perfecta del ESP8266 que ha sido tan popular. En comparación, el ESP32 tiene mucho más GPIO, muchas entradas analógicas, dos salidas analógicas, múltiples periféricos adicionales (como un UART de repuesto), dos núcleos para que no tenga que ceder ante el administrador de WiFi, procesador de mayor velocidad, ¡etcétera etcétera! Creemos que a medida que el ESP32 obtenga tracción, veremos a más personas moverse a este chip exclusivamente, ya que tiene todas las funciones.  Overview :  240 MHz dual core Tensi...

▷ #ESP32 - REAL-TIME CLOCK #RTC INTERNO

Imagen
⭐⭐⭐⭐⭐ #ESP32 - REAL-TIME CLOCK #RTC INTERNO Reloj en tiempo real (en ingles Real Time Clock, RTC) es un reloj de ordenador, capaz de mantener la fecha y hora. Perfectos para aplicaciones donde se requiere manejar el tiempo con precisión. En el mercado tenemos muchos módulos RTC para microcontroladores  tales como el DS1307 y DS3231. Son muy útiles y fácil de usar, por ello los tenemos presentes en varios tipos de proyectos. Sin embargo, es grato informarle al lector, que nuestras placas ESP32 no requieren de comprar dichos módulos, porque ya tienen un RTC interno que podemos usar. A continuación mostraremos la arquitectura de nuestro microcontrolador.   Si observamos en la imagen, uno de los módulos internos del micro es un RTC funcional, el cual el se utilizan en varios procesos, y en uno de ellos tenemos manejar hora y fecha con precisión, a lo largo de esta presentación, veremos como podemos usarlo y sacar el máximo provecho de nuestras placas #ESP32.

▷ #ESP32 - SINCRONIZAR RTC INTERNO CON SERVIDOR NTP

Imagen
⭐⭐⭐⭐⭐ #ESP32 - SINCRONIZAR RTC INTERNO CON SERVIDOR NTP Para muchos proyectos se requiere  un manejo de tiempo preciso, como ejemplo tenemos activar un sistema de riego a una hora determinada del día, o realizar una medición por un periodo de minutos o segundos. Para todos estos casos el uso de un reloj RTC es de suma importancia. En nuestro blog ya explicamos como utilizar el RTC interno del ESP32, lo puede ver en el siguiente enlace.  Si bien con eso tenemos un RTC preciso y confiable, el tener que ajustar la la hora y fecha manualmente para mantenerlos actualizados, provoca un mayor trabajo y una constante programación del dispositivo. La solución ante tales complicaciones la podemos encontrar en la sincronización con servidores NTP, aprovechando que nuestro dispositivo cuenta con una antena WIFI, por medio de internet podemos ajustar nuestro RTC a la fecha real, de tal manera que siempre se mantenga actualizado. ¿Qué es NTP? Network Time Protocol (NTP) es un prot...
