Plain and Simple LoraWan (LowPower) Library for STM32
It took a lot of time for trying, testing, debugging, but finally I managed to create a plain and simple LoraWan LowPower Library for STM32. Especially for the STM32L051C8T6 microcontroller …
MiniPill LoRa Form Factor
In the past month I designed different version of a PCB, all based on the original MiniPill LoRa node. Version 2.0 Smaller and Longer to fit enclosure After getting my …
LoRa Tracker for TTN mapper – Updated!
New: datarate selection As I was looking at the TTNmapper.org with my results and others, I saw that some measurements where done with other data rate. This enhance the reach …
LoRa node to track Bike – Updated!
In March 2019 this project was about to get tracking information from my ATtiny84 LoRa node in combination with the KPN (Netherlands) LoRa network. This network is speed out through …
MiniPill LoRa with RTOS
I wanted to learn RTOS and for testing I got it running on my MiniPill LoRa board. I want to use is for a (almost) realtime GPS tracker for usage …
Real life Low Power measurements STM32L
Thanks to Kim, who attended me on the Nordic Power Profiler Kit II, my tests on power measurements got a lot easier. Now I have a little post about power …
Pomodoro Timer
As I wanted to test a rotary encoder, I made a pomodoro timer, see also https://en.wikipedia.org/wiki/Pomodoro_Technique. In the lock-down phases during Corona I do use it to prevent long sitting …
LoRa Button
Just for experimental purposes and tracking with TTN mapper (ttnmapper.org) I made a LoR node with a button to send one LoRaWAN package. Of course it is based my own …
Co2 and environment meter with LoRa capability
This is a Co2 meter and environment meter: Temperature, Humidity, Pressure. With a rechargeable cell it is possible to use it with a USB power supply or standalone for about …
MiniPill LoRa – Low Power Node – STM32L051
After successful making a LoRa node with a ATtiny84 and BME sensor (https://www.iot-lab.org/blog/101/), I wanted to reproduce this node with a ARM processor. After 2 years of research and attempts, …
Programming STM32
For a couple of years I try to switch to STM32 microcontrollers. With ups and downs I learned how to handle these versatile microcontrollers. The first step was to be …
Mini Blue Pill – development board
In june 2018 I made my first SMD PCB to create a Bluepill clone. The goal was to 1) get more familiair with the ARM processors and 2) Reproduce my …
