Hi,
I have a problem to solve that may be solved using fibers. I
have no previous experience with fibers. We are working on a
variable-rate weeder. A camera is installed in front of a
tractor. A flame weeder is connected to the behind of a
tractor. Doing image processing (on RP3), we determine a weed
density rate and send a PWM signal to the LPG valve to adjust
the intensity of the flame. It is working well under lab
conditions so far. However, my control signal has to be
continuous with a delayed time shift. Because the tractor is
moving with a ground-speed, and the flame applicator will reach
the scene seen by the camera after about 1.5 seconds (I cannot
change the location of the camera for some bad and mandatory
design decisions). My pseudo-code is like:
[...]
A naive implementation would be to store 1500 ms worth of data
with the pwm values, like a buffer. I guess memory is not a
problem if you're using a RP3? Then just loop through and yield
depending on your sample rate (you didn't say what it was)
