    • MySensors on ATTINY85

      Good night to everybody, I managed to run MySensor in an ATTiny 85 micro.
      Unfortunately, i don't know too much about Arduino Bootloader and how this work,
      then I miss space in program memory...
      Now I can only make a Themperature sensor and I/O device but I miss space for
      configuration program.
      If somebody can help me...
      Thanks and sorry for my bad eglish.

      I share MOSI with 1-WIRE bus, I put in sleep mode the radio, then I read the sensor and after I send the value...
      Unfortunately I can't use only 3 pin for the radio module because I work with a botton battery (I can't swith off) and I need TX and RX

      I have already taken done to cut any library where possible (serial debug, utility / LowPower) I have already rewrite interrup WDT for sleep mode and pin change...
      Now I can only hope to take some byte from the arduino bootloader, but I don't know how?

      I choose ATTINY85 becaus I would like develop a sensor Network small, cheap and easy to make.
      But using an Attiny micro I meet a lot of problem with memory space ....
      For example when I using a DS12B20 temperature sensor I should send value
      without conver in Celsius degrees (I can't divide by 16).
      I would like undestaind how many space use the Arduino bootloader in an Attiny chip
      Thanks20150206_223853-2.jpg
