This project demonstrates the basics of using the MJD component "mjd_neom8n" for the GPS board "u-blox NEO-M8N".
Use it to get insights in how to use this component.
Goto the component "components/mjd_neom8n" for installation and usage/wiring instructions, data sheets, FAQ, photo's, etc. for the hardware and software.
The app initializes the GPS device, and reads the actual GPS data (fix_quality, coordinates, number of satellites tracked) from the GPS device using the ESP-IDF component.
The app demonstrates (simultaneously with reading the GPS data) the optional functions to control the power mode, to enable/disable the GNSS Receiver, to set the Measurement Rate, etc.
The app can read the actual / latest available GPS data with a simple function call, even when the device is powered-down at that moment.
- A decent ESP development board. I suggest to buy a popular development board with good technical documentation and a significant user base. Examples: Adafruit HUZZAH32, Espressif ESP32-DevKitC, Pycom WiPy, Wemos D32.
- The peripherals that are used in the project. @tip The README of each component contains a section "Shop Products". @example A Bosch BME280 meteo sensor breakout board.
- A working installation of the Espressif ESP-IDF V3.2 development framework** (detailed instructions @ http://esp-idf.readthedocs.io/en/latest/get-started/index.html).
mkdir ~/esp
cd ~/esp
git clone -b v3.3 --recursive https://github.com/espressif/esp-idf.git esp-idf-v3.2
- A C language editor or the Eclipse IDE CDT (instructions also @ http://esp-idf.readthedocs.io/en/latest/get-started/index.html).
- Run
make menuconfigand modify for example the GPIO PIN# that you want to use. - Run
make flash monitorto build and upload the example to your board and connect to its serial terminal.
Do you also want to create innovative IoT projects that use the ESP32 chip, or ESP32-based modules, of the popular company Espressif? Well, I did and still do. And I hope you do too.
The objective of this well documented Starter Kit is to accelerate the development of your IoT projects for ESP32 hardware using the ESP-IDF framework from Espressif and get inspired what kind of apps you can build for ESP32 using various hardware modules.
