Hello everybody,
I recently got Digilents Chip Kit UNO32 board and from the board specifications and also from what i have read on different forums i have found that this board is supposed to be a lot faster than an arduino board(about 23 times faster) . However it takes about 10 seconds for it to load the boot loader and in a recent project where i did some data acquisition from some sensors it performed quite bad.
I had about 6 sensors(1 sharp 1 paralax and 4 line sensors) and 2 gearboxes the robot should do some data acquisition from the sharp and paralax however they should at all times be conditioned by the 4 line sensors. I had the amazement that at times the robot would not go into the procedures triggered by the line sensors, or would have a big lag untill they did so , and would continue blindly to follow the sharp procedures.
example :
all of this would be in the loop function of the program
if lineSensor != ok
do something
if lineSensor2 != ok
do something 2
if lineSensor3 != ok
do something 3
else if allSensors == ok
verify if distanceMeasuredBySharp < aSpecificDistance then
make the motors to go forward
in this intuitive example my motors would go forward and at times not verifying the first 3 conditions as if the motors were spinning too fast and the board was unable to make the acquisition and take a certain decision
What do you think about this ? Do i need to load another boot loader in the board for it to perform nicely?
And by the way I am having some trouble with the sharp distance sensor its code is GP2D120XJ00F - measures from 3 to 40 cm. I am having some noise on it; I would appreciate if someone would give me a hint or a solution on how get rid of this noise.
Thank you for your time I appreciate the help;-)
Best regards:-D
