I’m successfully using the RFM69Pi with a wired pulse sensor by following this instructions:
I’ve seen that the firmwares available as dev, do not only extends RFM69Pi with a wired pulse sensor, but also 1-wire DS18B20 sensors, by using the dev firmware RFM69CW_RF12_Demo_ATmega328_Pulse_DS18B20
But as a newbie, no idea on where and how have to be wired the DS18B20 to the RF69Pi board pins, and this part (DS18B20 temperature sensors) is not documented in the blog entry mentioned above, so I do have a very basic questions:
- At the firmware source, I see that is using the 5 as a bus, but how this maps to the RF69Pi?
- For the other pins (VCC & GND) can be used the same as I’m using for the pulse sensor?
- Do I still need a 4.7k resistor between VCC & data pins?
