    I saw a note above somewhere asking if the transistor is important. The answer is yes. Alternatively an opamp with a sufficient slew rate should be good. Given the sensor performance, it can be a simple...

    One more question, I think. Are you using the logic inverter with your code? Would there be any issue in wiring the digital pins from the Teensy directly to the TCD 1304? Thank you

    BTW, the bandwidth of the Teensy 3.2 ADC input, seems a bit tight for this. Do you see any issues with that? What do you think of doing it with the 4.0?

    Thank you, I found that. Is there any reason you chose TX3, RX3 rather than, Tx2,RX2 or TX1,RX1? The pairs on the side of the Teensy are a little more convenient for routing a pcb.

    Hi Reim Could you include a listing, or a diagram, to show how you connected the TCD1304 to the Teensy? Thank you M Nelson

    Yes, I think so. My old installation ran the teensy loader from a separate directory. The current setup seems much better. I still have problems with the software complaining about running from the sketch folder,...

    The answer is that you unzip the Arduino wherever you want it to reside, and the Teensyduino installer copies itself into that directory tree. There are some bugs, the ide opens and closes without error message. You...

    I neglected to mention, it's a Linux machine. That sounds like it will be installed alongside the earlier versions, is that correct? I supposed the desktop shortcuts will simply be overwrriten.

    That is good news that it recovers after cycling power. At least it's not a total brick at that point. Apart from that, I think we have a different context for what is risky and what is normal, though I do agree on...

    Hi Paul We are again looking at deploying a product with the Teensy board. This one would be pretty important for a social minded cause. And again, we are still stuck on the problem of what happens when a user...
