    The last thing a developer wants to do is to debug the tools... I read that the proposed SW solution works, but not very stable on 3.X versions, and not so clear about robustness using 4.x either. A...

    Hi there!

    I would definitely vote for REAL debug capabilities, now that we have super powerful CPUs. Teensy 4.2 with 1062RT and JTAG, or SWD?

    It was really great to have that sort of debug...

    Hi.

    I intend to drive a 16 bit LCD 480x480 with an Hsync/Vsync/pixel clock interface, RGB 565, using Flexio 3 on T4.1. Reason why I plan on using Flexio3 rather than the 1 and 2 flexios is I...

    Well, what you really need is a iron with fine tip , of course, but the most important thing is a GOOD flux.
    You almost do not need solder , as most of the time the PSC almost has enough....

    @AndyCap

    thank you for the Vscode tips.

    Looks there needs to be a little bit more "packaging" to get a clean version of this debugging feature. I think this definitely makes the overall system...

    Hi there. The whole purpose of the tft interface is to be able to cope with slightly larger tft than 320x480. Sizes like that or smaller have built in frame buffer and the writing speed through even...

    When you say: Sadly, the parallel lcd data bus run through the GPIO B0_xx and B1_xx (for wider buses) > do you mean that there is no way to use the built in lcd contrôler due to...

    Ok, seems indeed that some checks are needed. I will test with 3 async clocks, and will check for errors. Underclocking may not be the best thing. Let's see and thanks for the warning.

    Hi Paul,
    Thank you for giving me a so fast answer.

  15. FreqMeasureMulti on Teensy 3.6 : precision over a few minutes?

    Good Morning,

    I would like to use a Teensy 3.2 or 3.6 to perform timings measurement of 3 digital signals.
    Those signals are expected to be digital pulses with a frequency of 1.5Khz up to 6Khz,...

    OOOps, you are right,

    I got confused with the naming. These are DMA interrupts, not ADC ones! Ok, very clear. Thanks for the reply!
