On this occasion I made our arduino communication with HMI Panasonic GT01 monochrome display via RS232 Modbus RTU, Arduino screen as Master and slave. Summary 1 The value of the ADC 0 of arduino from a potentiometer 100 k will be displayed on the HMI Panasonic 2 The value entered from a keypad from…
In the previous test, performs the communication between Arduino Mega 2560 and a Modbus simulator slave THROUGH the USB port that commonly have our arduino, in this case we will test with an Arduino as Master Modbus but via RS-232 with our PC – simulator modbus slave. Arduino Communication Modbus RTU Master and Slave Simulator Architecture Materials …
I start with the following question Arduino can be used in industrial aplicaiones? of course, using a common protocol used in the industry called Modbus Serial RTU in this case configured as Master. MODBUS communication is done by sending the value of A0 (ADC0) 10 modbus records using a potentiometer 100k variation is performed. …
In this opportunity we will simply perform tests on a ds18b20 sensor, indicating the library used in ESP-IDF, in future tests we will use other protocols, especially Modbus. Libreria: Simple library for single DS18B20 on ESP32 Materials Sensor DS18B20 (Onewire) + Resistor 4.8K Esp32 Devkit ESP-IDF V4.3 > Buy it here: Module ESP32 ESP-WROOM Mounting Buy…
This time we will test the module ESP32 TTGO T-Display 1.14 Inch , which has a IPS screen ST7789V 1.14 “ a resolution of 135X240 per protocol SPI , this module It has a USB type C for programming. We will carry out 2 tests: Test and configuration in Arduino IDE Test and configuration in…
From the beginning of PDAControl we have carried out tests with the Emoncms platform, the Openenergymonitor project, initial tests with the esp8266-01 in 2014 have brought us to 2021 and the ESP32 module. Using the Peacefair PZEM-016 meter add an ESP32 module and an RS485 converter module. In this case, we will carry out…
One of the applications installed in the Virtual Machine (VirtualBox) PDAControlMV based on Linux Lubuntu 20.04 LTS is ESP-IDF. How to download and Install PDAControlMV ESP-IDF ESP-IDF (Espressif IoT Development Framework) is the official programming platform Espressif for ESP32 modules. ESP32 Module Materials and where to buy them Buy it here: Module ESP32 ESP-WROOM…
Virtualization is one of the most used methods to facilitate the compatibility of Software or simply the test of other Operating Systems, technically it is an operating system within another. I have tried for a long time Oracle VirtualBox is one of the most used virtualization software for x86 / amd64 architectures allowing virtualization. FreeBSD…
Lubuntu LTS 20.04 x64 based virtual machine (Virtualbox). contains IoT software: Arduino IDE version 1.8.13 / Boards esp8266 v2.74 / Boards esp32 v10.4 Node-RED version 1.2.7 Grafana-server version 7.3.7 Influxdb version 1.8.3 Chirpstack version 3.13.2 ESP-IDF version 4.3-dev-2586-g526f68239 MySQL version 8.0.22 Mosquitto Broken MQTT version 1.6.9 We will create tutorials to test each of the…
In this opportunity we will carry out tests and explanation of the Modbus RTU protocol implemented in ESP32 requesting data from the Single-phase consumption meter PZEM-016. The intent of this tutorial is: 1. Explain in a simple way the creation and operation of an industrial protocol, in this case the Modbus RTU protocol used and…
