  1. Hello Guys, I have CC1310 Launchpad and I'm trying to attach an DS18B20 to it, but the library (Onewire.h doesn't have a definition for this board). Does anyone have a definitions for it, it will be great. Thanks George
  2. Hello, I'm try to use msp-exp430g2553et launchpad with energia but the serial monitor doesn't work. I'm using the example code:(One Wire DS18X20_temperature) I found it need to change RXD TXD but I changed it display "no more addresses" please help, thanks!
  3. I'm planning a project that requires me to have around a dozen temperature and humidity sensors placed around the house and the yard. These would connect to a central Arduino in the house that would log the data and send it to a database elsewhere. I have browsed the internet for solutions that work for long cable runs. For temperature sensors I found 1-Wire, especially ds18b20 sensors. However, there doesn't seem to exist humidity and pressure sensors that utilize 1-Wire. What is the easiest way to accomplish such network of sensors? RS485 seems to do great even with long cabl
  4. I have a problem interpretting the temperature reading of a DS18B20 chip. There is a certain situation I am not abble to resolve. This is the example temp table for the chip from the datasheet: an example for reading of -0.5*C is shown as FFF8. Cutting off the 4 LSBits we get 0x0FFF. In signed data structure that is equal to -1, not 0. How am I abble to resolve the difference between 2 readings: -0.5*C and -1.5*C? If 0xFFF8 = -0.5 then what is the form of -1.5? The table then shows an example for -10.125*C. Cutting off the 4 LSBits gives 0x0FF5 which really is -10, then there is no r
  5. Hi, I've finally found my "cahones" and decided to become a doer, and hopefully more active on the forum. I've been working on his for more than a year on my free time and have learned a lot. However, nothing real have come out of this project until recently. With the recent release of energia library for nRF24L01P by spirillis, I decided to restart working on it. Anyway. I'll post what I've done so far and move along with the suggestions. I'm a noob, so I've gone the noob way: Breadboarded first using what I had in my noob bin (msp430g2553 , nRF24l01P, ds18b20, thermistor, 7805, lm35
