Re: T41 SDT Code Issues
*** That sucks. Did it die completely, or just lose data? Sometimes they can be read by putting the drive in the fridge. I have a unique system. I don't keep anything important on my desktop PC.

What would be the cause of the display issues when some of us have ribbon connectors to the display that are 4-5" long? Jack, W8TEE

Re: T41 SDT Code Issues
If a new main board was designed... I think I would do what John did... sort of... I would put the main board right on the back of the display. That way there is no display cable. The thing is already

Re: T41 SDT Code Issues
If we were to redesign the Teensy - or just do a Main Board with a directly soldered iMXRT1062 - I'd want to free up the JTAG port for *hardware debug*!!!! It would speed up software development by an

Re: T41 SDT Code Issues
In its current state, I would say No, but others (Greg?) have added the extra memory chip but I don't know their results...perhaps they could enlighten us. Right now, our T41 code uses less than 3% of

Re: T41 SDT Code Issues
Jack I see that there are additional memory options that can added to Teensy. At some point does it make sense to swap out current Teensy for one with added memory chips? I see that it does not add a

Yep sorry.. .that¡¯s it. It IS on the new schematic. I think what happened is I tried to put it on the schematic (gave it one designator) and then I asked Oliver to do it and we got different part
