Experiments carried out in the past (from 2011) are described hereafter:
Contents |
May 2018
- I have received my Dragino LoRa gateway. Now I am able to send data from an Arduino (equiped with a Semtech LoRa transceiver) to a MTQQ broker (ThingsSpeak). Now, I have to build one or two measurement devices (to measure what?...). The challenge is to keep the energy demand as low as possible so that batteries do not need to be refilled too often. On possibility is to use a standard Arduino which spend most of its time in deep sleep asnd is awaken every 15 ou so seconds by a RTC. ANother solution could be tu use a very low energy msp430. To be continued...
- I have tried the Gogle Assistant SDK (tutorial here).
- (Still) playing with my Zturn Zynq board. I have managed to install Petalinux (on core 0) aside FreeRTOS (on core 1). See notes. .
April 2018
- Experiment Micropython on ESP32. See notes.
- Playing with my Zturn Zynq board. See notes. .
- Experiment the Ti MSP340 Chronos watch.
March 2018
- First experiments with the STM32 Nucleo (NUCLEO-F302R8) and motor control extension board (X-NUCLEO-IHM07M1), the STM32 Nucleo pack FOC and 6-step motor control: I am still fighting with the motor SDK... I am writing a note that will eventually explain in a how to setup the environment in a unique document ...
February 2018
- Built a safety case for my son, using a fingerprint sensor. Here are a few pictures:
The code is here.
January 2018
- Playing with the ESP8266 using the Espressif SDK. (Search for ESP8266 for other experiments using NodeMCU). I am using the PlatformIO environment. I am now able to print a message on the tiny screen from my laptop, through internet:
- Trying to build a doppler-based "fox hunter" (on-going). See notes here
