Hi,

Does anyone has made one of this work with Espruino?

It looks like the datasheet for the device is here:

The interface isn't great for Espruino, but it seems like it should be easy enough to make it work:

• Set OE = 1 (off)
• Set S0 = 0, S1 = 1 (for the low range frequency out)
• S2,S3 specify the colour to check
• setWatch on the output pin, and use the timestamp to work out the frequency
• digitalPulse(OE,0,1) (lower OE for 1 millisecond - don't do it for long or there will be so many oscillations that Espruino won't be able to process them all)
