code to use a TFT screen with arduino (will do a separated post one day soon

github stuff

  • unbox
  • wire
  • follow adafruit’s tutorial
  • enjoy!

To log data you can use picocom

picocom -b 9600 /dev/ttyACM0 > serial.txt

Adafruit’s ultimate GPS logger

Today I tested Adafruit’s ultimate GPS logger.
As usual, it was well documented on Adafruit’s site.

I took the first example from the tutorial and this was what I got:

And here are the pictures from the soldering:

1.8″ TFT Adafruit display(ST7735) and Arduino uno

draft

Install Adafruit ST7735 Lib and the Adafruit_GFX library for Arduino.

I had to upgrade ino to 0.3.6 in order to be able to build the example srcipts:

pip install --upgrade ino

I renamed the example files to .ino (’cause .cpp & pde gave errors)

Make sure you name the directories as in the documentation.

Then I built it using inotool.

send SMS with arduino GSM shield

DRAFT

Recipe:

  • sendSMS example sketch from arduino
  • picocom [1]
  • SIM card from a French local provider
  • The serial monitor from the Arduino IDE can be used, too.



    to quit picocom C-a C-x !!

    [1] Don’t have what I type echoed, which is frustrating

     picocom --omap crlf --emap crcrlf,delbs --baud 9600 /dev/ttyACM0
