@KurtE: Yes, you remember correctly, and yes, one of those two lines needs to be uncommented in order to support the respective touchscreen (& I have included instructions at the top of my example template sketch on the necessity for doing so)...

Sorry, I forgot to answer your other question . . . nothing in the example template sketch should cause any adverse effects with respect to PIN 13. If you are getting something/anything on the display (& you indicated earlier that you are seeing...

@AntiLoop: OK, good that you've confirmed to have the same ER-TFTM070-5 from buydisplay.com. Since you are troubleshooting problems with the touch, did you select the "capacitive touchscreen" (as opposed to the "resistive touchscreen") when...

@AntiLoop: Since you specifically mentioned using the Adafruit libraries in your earlier messages, I did some independent checking on the Adafruit website. Based upon what I saw, it seems like you may be using one of the displays with a...

@AntiLoop: Not sure what may be going on with your hardware setup, but independent of that, the example template transitions from the splash screen to the operational screen automatically after a 4-second delay (not touch dependent). You'll...

@AntiLoop: I have not used the Nextion displays in any of my projects so far. For my larger projects (i.e. needing more display area and/or larger readbility), I primarily use the RA8875 7" 800x480 display. For my smaller projects, I have been...

@AntiLoop: I developed this button & slider approach to a user interface while creating the latest version of my TeensyMIDIPolySynth (TMPS), which is a (work-in-progress) digital synthesizer built around the Teensy 4 & the Audio Adapter, mostly...

@AntiLoop: [ EDITED ] Not sure if the attached template will help you with your current challenge, but I wrote this template as a simple example of how I support a state-driven menu system (for example, with buttons at identical locations...

The description of the RED LED blink codes can be found at the bottom of <this page>. As you can see from that description, 2 blinks indicates that JTAG (which is used for critical communications between the MKL02 boot controller and the IMXRT...

As one might expect, same experience (Norton objected, told to exclude process, then success) as reported in P#2 (& detailed by @KurtE in P#7) above. Mark J Culross KD5RXT

Using Arduino 1.8.19 under Win11pro. Attempted installation & received an unusual warning from Norton 360: Category: Data Protector Date & Time,Risk,Activity,Status,Recommended Action,Status,Program Path,Program Name,Date & Time,Action...

Yes (in KiCAD 7), the clearances can be adjusted in the "Board Setup" menu, specifically the settings under "Design Rules" then "Net Classes", either by adjusting the "Default" (for all traces, if that's all that you are using), or by adjusting...

If you prefer a pure hardware solution, you can initialize pins 30 & 32 as pinMode(xx, INPUT) in your setup() function. Then add a bodge wire between pin 30 & pin 0, and another between pin 32 and pin 1. Mark J Culross KD5RXT

You might take a look at <this> post discussing how I previously (successfully) used the 75HC595 to drive a large number of LEDs as indicators on an earlier version of my TeensyMIDIPolySynth. Using this shift register only consumes a couple of...

Is <this> what you have ?? Or, maybe you have <this> older version ?? Mark J Culross KD5RXT
