Meeting with George Sullivan

When testing the motor functions, the motor was getting warm again. We think that having the high pulse on for too long and/or having a small step frequency was heating the motor up. This should be verified by a professor who is more familiar with motors.We reviewed the data sheet for the motor driver, specifically page 6 http://www.ti.com/lit/ds/symlink/drv8805.pdf In the table it says that the smallest high pulse can be 1.9 microseconds. We tested 40, 30, and 20 in the SysCtrlDelay function and got the high pulse duration pretty small but not exactly 1.9 us. Before, in the sysctrldelay I was using 15625 which corresponds to 266.5 Hz or 3.752 ms. Below is a doodle:

Using an example George found online and the TI's example with Code Composer, we got the UART working. George explained how some of the ADC example code was working, but we didn't have time to debug everything Friday. In the picture below, I was trying to get the ADC to work. I think the 300ish number is representing a very small voltage.
