Project Goals

  • Learn to connect a popular 4 channels ADC Module to the 3.3V S5D9 IOT board.

  • Examples show how to connect it to either grove A (r_sci_i2c port) or B (r_iic port).

  • Examples show either configuration with and without using framework.

Project Goals

  • Take what is developed from Part 1.   

  • Add an external SHT31 sensor. (new hardware) 

  • Change the code to read the current temperature (F) from an external SHT31 sensor instead of an onboard AMS EN210 sensor. (software change)

  • Add the...

Project Description:

This is the follow up Arduino project that built on the first version.    Because the 433Mhz RF chip has short range issue and the data is frequently dropped,  this project is to choose a better reliable radio frequency module to replace it.    2.4G...

November 10, 2017

Project Goals

  • Develop the basic C code from scratch for the S5D9 board

    • Read the current temperature (F) from onboard AMS EN210 sensor (I2C interface).

    • Display the current temperature (F) on OLED display (I2C interface).

    • Display the...
