I am using AN pin because I would like to use more than 5 sensor. Now, I just use the evaluation software for the tms320f2812 provided by the company to test the sensor. I am using ADC module application. When I connect the AN pin to the ADCINB0, the output is fine but not changing while I change range of the distance of the obstacle(here I using box). If I off the evaluation, then change the distance, turn on the evaluation, the output will change according to the distance. Why it is like that? I think supposedly the output will change with the distance without turn off the evaluation. Then, when I connect it to the other pin of the MCU (ADCINB1-5), the output will static at 0.825V even I change the distance and turn off and on the evaluation. Do you have any idea about it?
"There will almost definately be a library in you software which gives easy to use functions for use with the usart."
What do you mean by usart?
