Qhov:

  • Arduino Nano lossis Arduino Pro Mini
  • Nokia 5110 84x48 LCD
  • DHT11 kub/av noo sensor
  • DS1307 lossis DS3231 RTC module nrog built-in AT24C32 EEPROM
  • Pheej yig encoder nrog 3 debouncing capacitors

Nta:

  • GUI raws li Nokia LCD thiab encoder
  • kub, av noo, hnub tim thiab sijhawm tuaj yeem khaws cia txhua 1 txog 120 feeb
  • txhua cov ntaub ntawv tau nrawm rau 39 bitfield nkaus xwb yog li 32kbit flash (4KB) tuaj yeem haum 819 cov ntaub ntawv
  • yeem AT24C256 nti tuaj yeem khaws txawm tias 6553 cov ntaub ntawv
  • pw tsaug zog siv los cawm roj teeb, ATMEGA tau sawv los ntawm kev cuam tshuam feem ntau
  • DHT11 tsuas yog siv tau thaum ntsuas
  • siv los ntawm ib leeg 18650 lossis lwm lub cell lithium
  • ob peb zaub "ntsej muag"
  • 6 fonts ua
  • roj teeb qib ntsuas
  • cov ntaub ntawv tshuaj xyuas thiab teeb duab
  • min/max nrog hnub/sijhawm
  • tag nrho cov ntaub ntawv kaw tseg ntawm qhov chaw nres nkoj hauv hom CSV
  • LCD rov qab teeb
  • tus kheej cov peev txheej nrawm thiab qis N5110 siv
  • tus kheej qib qis DHT11 nyeem cov ntaub ntawv
  • tus kheej DS1307, DS3231 thiab AT24C32 I2C EEPROM tuav txoj cai
  • txoj cai siv yuav luag txhua 32KB Arduino flash
  • txhua daim ntawv sau npe sab hauv tuaj yeem khaws cia hauv EEPROM lossis DS1307 sab hauv RAM

Cov ntaub ntawv compression

Cov txiaj ntsig hauv qab no raug kaw:

  • sijhawm (teev, min)
  • hnub tim (d, m, y)
  • kub
  • av noo

Cov ntaub ntawv saum toj no tau nrawm rau 39-ntsis bitfield:

  • hr 0..23 -> 5b
  • min 0..59 -> 6b
  • d 1..31 -> 5b
  • m 1..12 -> 4b
  • y 2018..2021 -> 2b
  • temp -40.0..64.0 -> 1024values = 10b
  • hwm 0..100 -> 7b
  • tag nrho 39 khoom

Tsuas yog 5 bytes siv rau 1 cov ntaub ntawv:

N5110 lub tsev qiv ntawv:

github.com/cbm80amiga/N5110_SPI

Kev xaiv teeb tsa:

#define USE_DS3231 -> siv DS3231 siv DS1307

#define REG_IN_RTCRAM -> cov npe sau cia hauv RTC RAM (tsuas yog rau DS1307)
