I recently obtain an LM3S811 http://www.ti.com/tool/ek-lm3s811
evaluation board and an MLX90614ESF-DCI http://www.amazon.com/JMT-Mlx90614esf-d ... B00A6P2YF8
infra-red thermal sensor. I am a software developer but not very knowledgeable about embedded systems that is why I wanted to learn and be familiar with this field. You can consider me as a newbie. I am currently using an IAR IDE that comes with the CD from my evaluation board. I have managed to understand the potentiometer, user button and LED display functionalities and managed to create a custom program from those I/Os. Now I wanted to learn how to work with GPIOs or the pins connected to my evaluation board. To make the story short, I wanted to try to make a program that can read a temperature from SCL and SDA and display the result in the LED display with the setup like on the picture below. I have looked at the samples from the CD and the web for I2C but I can't follow the explanation on how I2C works. I was wondering if anyone have already made a same project as mine and provide some example for IAR IDE. Any help will be very much appreciated.
