For umbrella project I build my own power supply system.   - solar panel (3V, 80mA) - storage/battery element (LiPo rechargeable battery from Fuel Tank BoosterPack) - my own universal solar charger device (based on TI bq255040 ) - TI TLV70433 LDO (3,3V, 150mA)       Designed by my universal solar charger is based on TI bq25504         Solar charger parameters are configured by resistors. -          b ...
I picked up a helper to move the engineering side along a little more quickly, so I finally have some time to post. As a total rookie, the learning curve to get the TI to bend to my will is pretty wicked.   The last month+ has flown by. The biggest challenge we have faced is getting bird photos taken. Would have been amazing if the TI camera booster pack had ever become a reality as an off-the-shelf product. Oh well!   A close contender for number one challenge has been the behavior ...
In my umbrella project I used gps module. After start  device turn on gps module and waiting for geographic position . Latitude and longitude values are used in weather forecast algorithm.   If user dont have gps module, then he can turn off gps positioning function in umbrella code (c/c++ compiler -> options -> proprocessor -> defined symbols ,,, and remove GPS_IN_USE ). After that user must set name of city where umbrella is located (definition in configure.h file). When gp ...

I finally have my cc3200 Launchpad posting data to Plot.ly using Energia (www.energia.nu) compiler / Wiring framework. It took awhile to sort out but feels great to finally get all my charts initialised in the correct format and my data streaming to Plot.ly.   Energia is very well suited for my purposes of linking up to the WiFi network and posting data. It is quite straightforward to amend the included examples for WiFi to connect to your home network. I had no problems at all (unlike its ...
In project I used lcd from nokia 5110 (PCD8544 driver), It is monochrome graphic lcd with resolution 84x48 pixels   In used ready hardware ( foto below ) and connected it into CC3200 LaunchPad ( schematic below )     Communication with lcd is done via SPI ( in one side mc->lcd )   I wrote software spi algorithm (code below ) void LcdSpiInit() {     // Configure PIN_05 for GPIOOutput (SPI_CLK)     MAP_PinTypeGPIO(PIN_05, PIN_MODE_0, f ...

from 8 years I write articles about Texas Instruments products ( the most about MSP430 microcontrollers )   now I will start writing course "MSP430 with FRAM in examples" (course based on LaunchPad MSP-EXP430FR5969, MSP430 Wolverine series) In attachment I share first part of this course "Introduction. LaunchPad description" In next parts will be presented practical projects.   unfortunately all my articles are in polish   b.r. Lukasz, Poland ...
Thanks to an unseasonally warm September month I finally have plenty of long grass to work with...     and the grass sensor node is coming along slowly but surely. Here is my first attempt at the grass node sitting in shorter grass... yes I mowed the grass too (well most of it as still need the long grass for testing).     By way of summary of progress.... not quite like clockwork...   Quite a few mistakes were made on my first build attempt. Firstly, the placemen ...

So far the medication is not clearing my head, but I thought I would share my design so that others can copy any useful bits.   As I stated earlier, I am using a RF circuit to catch the electromagnetic pulse for a lightning strike. Basically, you have a piece of wire connected to a 10 Meg ohm resistor coupled to an op amp with a capacitor. The prototype circuit I made picked up the signature of the switching power supply I used for the test, so the circuit works.  I will have to loo ...
my umbrella should be protected against destroy what can destroy umbrella  ... of course strong wind ! so I am start developing wind sensor (anemometer)   below is real foto of anemometer elements (additionally is mounted gps module):     up this time 1. I bought all needed elements ( turbine, encoder, wires ) 2. I wrote frequency measure algorithm (timer in capture mode)   now I must make : 1. write software incoming data filter 2. create hardware LF RC filte ...
