  1. Sensirion has recently introduced an inexpensive, low-power temperature humidity sensor SHTC3 designed for operation in the range 1.62--3.6V . It should be a useful peripheral for MSP430 battery-powered applications. I have tested 3 sensors with the F5529 Launchpad and they exhibit reliable, consistent behavior. For reference, I have written some demo code for I2C communication that is available on github: https://github.com/microphonon/SHTC3 The SHTC3 comes in a small DFN package, so to do breadboard testing I had to build my own breakout boards and use reflow soldering (see phot
  2. The Bosch BME280 pressure-temperature-humidity sensor is very popular for projects because there are breakout boards available from Adafruit and Sparkfun as well as a large library of code to interface it to Arduino MCUs. Not so much for the MSP430, especially transparent code to understand what is happening at the register level. I have written and tested some demo C-code that hopefully fills that gap. It sacrifices generality and efficiency for compactness and transparency. I use the F5529 Launchpad and communication with the sensor is via SPI using the UCB0 module. I2C is also availab
  3. There is code available to implement I2C communication between the MSP430 and the HDC2010 temperature-humidity sensor, but it's a bit like an onion -- you have to peel away layer after layer in various libraries to drill down into what is happening at the register level. I decided to write some transparent demo code for this sensor that is self-contained: everything related to the I2C interface is in a single C program. It has been successfully tested with the F5529 Launchpad. This is a simple MCU polling operation that periodically makes a T-H measurement using the on-demand mode of the se
  4. Sir , how to code senshub with CC3200 for sensing humidity and the environmental temp. Is any modal prog available for this sir
  5. Hi all i'm programming by MSP430fr5739 a temperature and humidity reading by the DHT11 sensor. ?The wire are correct, and so the problem is'nt in the link, it is in the code. This is my code, usind the dht11 library, find on internet. ?The main problem is that i don't know how to read the value of T and H, and maybe there is some problems in the reading (probably in the interrupt) ?Thanks for the advice. ?MAIN CODE: #include <msp430.h> #include <DHT11_LIB.h> unsigned char RH_byte1; unsigned char RH_byte2; unsigned char T_byte1; unsigned char T_byte2; unsigned char checksum;
  6. Hello everyone, I just started programming in C ++ to solve a small university project. I am a newbie in programming that's why I ask you a hand in writing the code. I'm working with Msp430fr5739 and the temperature and humidity sensor is the DHT11. The connections have already been made and we have to write the code. I already have the library DHT11 and I'm working in CCS. Can someone share a code that works and allows me to read the values of temperature and humidity? Thank you (and sorry for my english)
  7. Here is the zip that bluehash requested that I post. Tested with DHT11, output to an LCD. Here is the original post: http://forum.43oh.com/topic/2826-ladyadas-dht-library-lcd/ AdaDHT11.zip
