Thanks Kurt. The LED pin is conn to VIN thru a 100Ω resistor, which works fine on the smaller display. The first thing I tried was upping the resistor to 100k, but that made no difference to either display. Tried conn to 3.3V - with and without the resistor - no change to either display. I'll...

I have two different TFT ILI9341 touch displays, running on a teensy 4.0 using the ILI9341_t3n library. The smaller 2.8 display runs exactly as expected and it's back lit correctly. The larger 3.2 display runs ok, but it's like the back light is too bright? I'm not sure where to start looking...

Anyone have any experience running tycommander on macOS Monterey Apple Silicon (M1) machine?

M1 I'm hearing about tycommander not working on the macOS Monterey Apple Silicon (M1) machine (it launches but can't find the connected teensy I think). I don't own an M1 so I can't verify what may be happening. Anyone know of a workaround?

I see, thanks for that. SPI.setMOSI(pin) SPI.setMISO(pin) I'm about to start some very simple GUI experimenting with the little ILI9341/XPT2046_Touchscreen touch screen (same one as this https://www.pjrc.com/store/display_ili9341_touch.html) I'd like to get this working on the LC, but T3.2...

Thanks Bri. #include <ILI9341_t3.h> #include <font_Arial.h> // from ILI9341_t3 #include <XPT2046_Touchscreen.h> #include <SPI.h> #define CS_PIN 6 #define TFT_DC 9 #define TFT_CS 10 // MOSI=11, MISO=12, SCK=13 XPT2046_Touchscreen ts(CS_PIN); Since my pins 11 and 12 are already in use, how...

From Paul's touchscreen on github: https://github.com/PaulStoffregen/XPT2046_Touchscreen What does " used automatically" mean? Thanks!

Nice, thanks! Shortly after my post I dove in and got the TPS65 working with the Azoteq CT210A configuration tool back in May - as you say, there is a lot you can do with these little beauties. I've been away working on other projects, but it's time to dive back in and wire it up to the teensy.

Anyone attempt to use these nice little I2C touch boards? https://www.digikey.com/en/products/detail/azoteq-pty-ltd/TPS43-201A-S/7164940?s=N4IgjCBcoLQExVAYygFwE4FcCmAaEA9lANogCsIAugL7X4KSkAqACgMoAsAzFdUA What alternatives boards have you used for X/Y touch tracking? Thanks for any...

Yeah, so I may just have to leave my USB config setting to be "Serial + MIDI" do just that and running your code again finds the teensy. Why tyCommander and the Arduino IDE don't need that to find and communicate with the teensy is above my current pay grade. :) Thank you! COM1...

Running @macrosii python code on windows 10 resulted in this. COM1: Communications Port (COM1) [ACPI\PNP0501\0] COM1 Communications Port (COM1) ACPI\PNP0501\0 ****************************************** Device not found It must be noted that the teensy LC is configured as USB: MIDI I know...

Holy smokes, thank you Paul! Great story and helpful response.

I can run the python code without errors, but the teensy is never found on my windows 10 machine. None of the above examples find my teensy, by TyCommander finds it just fine. :(

I'm searching but not finding anything regarding general guidance around how far away things, like buttons, can be when wired directly to the Teensy. Are we talking feet or just inches? Has anyone tested this? I'm thinking there are likely viable alternatives to get around any limitations, but...

woops, yes! A serious case of the upside down and flipped around, blues. This will work better:

You know, the specs get you only so far.... it's how you use it that counts!

routing USB V & signals to teensy LC directly, bypassing the teensy micro connector? I want to avoid using the Micro usb on the teensy LC itself and want to do something like this, in the image below. I tried removing the image what was wired wrong, but can't see how to do that... anyway, see...

Nice! I'll take a look, thank you @luni !

I'm looking for a very generic way to send config data to teensy. I envision something like this: open a GUI application that can detect the teensy (select it from a list of connected devices?) select the teensy you want to talk to In teensy land, press and hold a button to put your code...
