Mateusz Grzywacz / Mbed 2 deprecated Nucleo_praktyki

This is some program for air quality monitoring device. Its capabilities span quite a broad range: -read sensor (selection of 2 kinds - both worthless actually) -store measurements on SD card (nice formatting included ®) -display current measurement on LCD -sleep between measurement (but on my Nucleo platform power draw was still unacceptably high) -change measurement interval with on-board keys

Dependencies:   DS1307 DS1820 DSM501 GP2Y1010AU0F I2CEeprom SDFileSystem TextLCD_YWROBOT WakeUp keypad_ADC mbed

The device has no upload capabilities. It logs data onto local SD card if one is present. It displays current measurement nevertheless.

I used some libraries: some purpose-made, rest forked public libraries. main.cpp file contains the program. First it initializes modules (EEPROM, RTC, thermometer, dust sensor, LCD, SDcard), then enters endless loop of following sequence:

  • take a measurement
  • display measurement and save it to the SD card
  • enter sleep for *sleep* period
  • repeat
