Thank you Paul. Much appreciated. Regards, Tony Barry

Thank you Paul for the reply ... the term "IMXRT1062DVJ6A" being the IC number for the Teensy 4.1 processor appears here:- https://www.pjrc.com/teensy/techspecs.html (in the table) https://www.pjrc.com/store/teensy41.html (in the schematic as you noted, and on the photo of the Teensy 4.1...

Thank you defragster. Much appreciated. The B item is classed as "New" by Mouser and I presume NXO. That implies seven years of production. Plus some rattle room. Regards Tony Barry

Hi, I am considering Teensy 4.1 for a project which may become commercial. I find from Mouser and NXP that the IC MIMXRT1062DVJ6A which powers the Teensy 4.1 is listed End Of Life. https://au.mouser.com/ProductDetail/NXP-Semiconductors/MIMXRT1062DVJ6A?qs=0lSvoLzn4L9s91DnqP7Crg%3D%3D " ...

Thank you for this explanation, defragster. Very helpful. Regards, Tony Barry

Thank you for your comment, thebigg. There are many things that I have missed the significance of. Coming from a microcontroller background for the past forty years, I am sure there are yet more things to be discovered. However, if you can explain how ... Wire.setSCL(pinNumber) is meant to...

Hi defragster, Thank you for the reply. The pin numbers came from the PJRC Teensy 3.5 Pinouts page. https://www.pjrc.com/teensy/pinout.html Scrolling down to Teensy 3.5 Pinouts, we find that pins 3 and 4 are listed as follows:- Pin 3: PWM CAN0TX SCL2 Pin 4: PWM CAN0RX SDA2 For interest...

Thank you defragster. Your solution works. For those who experience the same issue I had with the i2cscanner example and Teensy 3.5, the solution is 1. Do not use the commands Wire.setSCL(3) or Wire.setSDA(4) to access I2C transfers on pins 3 and 4. 2. Instead, change the following multiple...

Howdy all, I am using the standard Wire library and the Example program "I2Cscanner" in the Examples with a Teensy 3.5. Teensy 3.5 has default Wire pins as SCL0 on pin 19 and SDA0 on pin 18. I want them to be on SCL2 as pin 3 and SDA2 as pin 4. This is approved of by the Teensy docs. The...

Thank you for this info Paul, it is much appreciated. Do you know where there is a collated tutorial on "speedy IO for the Teensy 4" ? Presently I am finding that all info is on the forum, widely disseminated. The responsivity of the forum is very gratifying, but repeated questions all...

Thank you thebigg !

Hi DukeBlue219, I am with you on this one. I am attempting digital video acquisition from a analog camera's ITU-R BT.656 port, and need 11 bits (8 bit data, clk, hsync, and vsync). About The clock runs at 28.5MHz so I get 17nsec max to read in the data. I really want to be able to do one...

Thanks Rat, good to know. I also have ordered them, but this thread starts with an admonition from Robin that PJRC has distributors, and of they are not on this list then they may well be not legit (i.e. PJRC does not get funds from the sale). Since I want PJRC to keep making Teensy 4.1 I am...

Hi Robin, Core Electronics sells your stuff in Australia. https://core-electronics.com.au/f/teensy.html Are they legit ? Regards, Tony Barry

Having had the same question within the last two weeks or so (and being told "Read the 2500 page manual") I thought to offer the following thread as a good distillation of the solution:-...
