• @Joseph-Macaulay Hi, this is the sketch that I use for Themp sensor

MySensors85.ino

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
Thanks

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.
