Code for determining the location of a ball thrown through a laser sensing grid.
512-QSD123 QSD123 4mA PHOTO TRANS Rise/Fall time = 7 Microseconds (should be fast enough...)
72 sensors need to be read for a full reading From beginning of the while loop to the end of reading 72 sensors needs to run in about 1 millisecond. A JavaScript simulation without the time of reading sensors ran this in about 30 microseconds
Takes about 100 microseconds to read, plus whatever processing we have to do with information. This will likely be the issue, if done once per sensor, this is 7.2 ms even once per shift register is 900 microseconds, which only leaves 100 microseconds for the rest of the processing. Which actually might be possible.
