    Thanks, I have implemented it with SdFatSdioEX (have also tried SdFatSdio) which are working well. I have noticed that if the SD card is removed while the Teensy is running, it freezes up for long...

    Datalogging to an SD card (Teensy 3.6)

    Hi all,

    I am working on a personal RC (remote control) project with Teensy 3.6, datalogging information to the builtin micro SD card. I have encountered a small problem I need to try and fine a...

    Hi Folks,

    I've tried searching around but wasn't able to find much info on what the difference between the various optimization options are - Fast / Faster / Fastest and there are with LTO options...

    Thank you very much for the guidance, I have changed my code and it's now much more accurate (no jitter at the microsecond level). This is the new code I am using, posting here perhaps it can help...

    Advice on reducing PWM "jitter"

    Hi Folks,

    I am using a Teensy 3.6 to time PWM pulses from my RC receiver. I've noticed there is about 1 microsecond of "jitter". Is there any way to reduce this? Here is the ISR code I am using....

    Thanks. I'm just trying to ensure the code is as efficient as possible. Can you explain how digitalReadFast() differs from digitalRead() ?

    I tried this but it seems it's only possible to attach an interrupt routine for one or the other (e.g. FALLING or RISING), but not both. Perhaps I'm making a mistake.

    Efficient CHANGE interupts

    Hi Folks

    At the moment when I receive a pin CHANGE interrupt, I'm doing a digitalRead() to determine the state of the pin HIGH or LOW. Is there a more efficient way to do this (i.e. avoid doing...

    I have been using the Arduino Servo library writeMicroseconds() function to control the servos. I'm guessing there is a way to do this on the Teensy3.1? (sorry for such newbie questions, it's just...

    Thanks. The digital side looks good as all pins have interrupt capability. On the analog I found (on the mega328) the analogRead() took a little while and caused other parts of the code which timed...

    Hi

    I had a look at the sample ADC code on the website which was referring to these registers but I've just realised it's for Teensy 2.0. I'm hoping to set up the ADC in free running mode and...
