Speed on the tube Technical parameters:
- On the tube manufacturers: the United States HP HP original
- Supply voltage: 5V (3.3V also available)
- Wiring method: Red 5V Black GND
- Output signal: 5Vp-p two-phase signal output (see below).
Two signal lines, a yellow one blue (due to the production of different batches, sometimes the signal line may be green, does not affect the use), yellow and blue are two TTL level (can be directly connected to the microcontroller ) Signal (Note: measured positive and negative is by the two levels of distinction is forward or reverse)
(Let A B be the signal line)
A first pulse, proved to be turning
B first pulse, proved to be reversed
Important note: a long time to block or no block are not output, as the phase detection, only in the rising and falling edge of the shot will have a waveform output, so turn the code or use the opaque object to switch back and forth when the state will be square Wave output, high-speed state, similar to the sine wave or sawtooth wave, see the following video demo. Multimeter test has been expressed as 0.1V or so, is invalid!
