<![CDATA[CCD Line scanning sensor]]>A line scanning sensor could be useful for many things:

  • flow detection
  • rotary counter detection
  • water, volume detection
  • line following
    ...

Wiring in itself is quite easy (see arduining):

some code on github can be found.

Afterward you get a lot of information on the console that is hard for me to transform to know if the read value is good.

The sensor has a 64 bit shift register which uses a clock signal and serial input. You need to clock in the 64 bits one by one and generate a clock pulse for each bit. Then read out each bit as an analog value on AO, and continue with the next bit.
This thing is not i2c, spi nor i2s (audio only), but defines its own protocol.
Connect your logic analyzer to clk and si if you like, but you also need an oscilloscope or so if you want to see the analog output values.

so I ordered a TSL1401 and will put that on hold till I receive it or a superb idea would come through... at least I learned the shiftIn command...
