I would like to ask if it is possible to obtain information about the activation time of the SparkFun 2D Barcode module? I mean the time of the so-called “cold start”, i.e. the time from the moment of power supply to the module’s full readiness for operation.
Eh, not really https://cdn.sparkfun.com/assets/b/5/0/e … df…it’d heavily depend on the type of code being scanned and where in the cycles that type falls (I’d guess regular 2D barcodes scans are run/checked before more complex QR code algorithms, it also might not make a difference at all)
But, I would hazard a GUESS that it’s somewhere between 0.25-2 seconds? If you end up testing this and finding it out please post your results!
