Yes that would! Although I didn't even know that that information existed. Or, there was a link to something like that. In fact, Once I look at it, I see there's all the info I was looking for. But...

Too much information? Not in the least! I'm grateful for it.

I asked because, in my project, I'm stuck. And, I ran into a bit of a informational void on all of this. On the Arduino side I get...

Thanks! I've never had this spelled out to me before and its always been kinda' a mystery/blind spot.

Or is Serial the same as Serial1 ? I tend to doubt that though..

Thanks!

-jim lee

Nevermind..

Um guys?

My background is very weak in compiler and linker vocabulary. In the end of all this, was there a list of things I need to do to get this library to work? I just tried the basic.ino...

Ah, ok. I came into this late.

It caught my attention because I have a GUI application framework I've been working on for my stuff and, at one point, I kinda' bailing-wired ILI9341_t3 in to see if...

KurtE, You wrote ili9341_t3? I had no idea!

-jim lee

WildBill (Arduino forum) Helped me get the OLD codebase compilable on Arduino. (Teensy 3.2) I developed the handheld and the GUI. Then worked on rewriting a bunch of the code to integrate it on the...

Dont fear soldering. Its EASY. ..IF you have the right equipment. A decent solder iron and high quality, rosin core, tin/lead solder. 99% of soldering issues are crappy equipment and supplies....

Well, for starters, what part of the planet are you located in?

I have teensyduino 1.8.7? On my work machine. I decided to try programming an Adafruit Itsy Bitsy M4 with bluefruit thing. And had no end of issues. I swear it was switching processors on me while...

Thanks! And again, thank you! Finding that it worked on your machine kinda' tipped the scales on getting this figured out.

GOT IT!

If you DON'T initialize the Adafruit ILI9341 screen. Even though your not using the screen. It subtilely messes up the SD card function. Init the screen drivers, and everything's fine.
...

Upgrading to Teensyduino 1.52 didn't help. The other change I did was to use ILI9341_t3.h instead of the usual library. I'll have to swap that back and see if it changes anything. If its a scope...

THANK YOU for testing this!

Both SD cards are mounted on Adafruit #1947 Cap Touchscreen shields.

My arduino is 1.8.12
My teensyduino is 1.51
I've tried 3 different cards all were in use by...

I've now tried the supplied Teensy readwrite example on two different sets of proven hardware, and the results look to be the same.

-jim lee

I tried the supplied Teensy readwrite example and it behaves the same way. First time through it can't create the file. Subsequent times it can create it, but not write to it.

-jim lee

Pretty cool! I never would, have thought that would be possible. But it makes my head hurt just thinking about it.

-jim lee

Few odd issues.

A) I can't seem to be able to create a new file. This is intermittent. Sometimes the new file is created.
B) I can't write to an empty file using print(). This is NOT...

Ok I feel dumb. Those are not OLEDs at all. Should have looked closer first.

-jim lee

If those are OLEDs, the'll be toast pretty quick unless you have some sort of screen saver written in there. Something that lets them sit blank for all that time no one is bothering with them. I...

That is incredibly cool!

Why not just add a passel of Teensys? Then you can bust up the coding making it easier to write and faster to respond, and you end up with more pins that you'd ever need....

I have my cellphone at a stopping place. (Moslty working, I'm tired) Wrote up a BLOG on developing the software for it.

Enjoy.

Quantum physics! Nothing exists without an observer. :D

-jim lee

I can not believe the frame rate your getting for drawing anything to that screen. My ILI9341 takes seconds per frame. It drives me nuts! Who is this kurt and his ILI9341 library?

-jim lee

After a day of hacking on my teensy stuff I quit the teensyduino and it took the entire mac down. Power off, everything.

I don't know if it'll help, but here's the stuff apple wanted as a report....

Well, your guesses are at least putting me on the right paths. Thank you! The loader didn't come with the installer. So, I thought it was no longer needed with this new fancy stuff. I went back and...

Ok, I pulled ILI9341_t3 stuff out for now. Went back to the original one from Adafruit. Got everything to compile again. But now there's no teensy loader? Is this not included with this new...

Well, here it is. Looks like teensyduino has a private copy of Adafruit_GFX.h


Multiple libraries were found for...

AH! Got it. Teensyduino has the teensy stuff in it. Then new IDE from Arduino does not. I'd forgot to check to make sure I was compiling for a teensy. So I guess it wasn't looking for teensy library...

Back out of the saddle..


#include <Adafruit_GFX.h>
#include <ILI9341_t3.h>


void setup() {

}

Cool thanks! Back in the saddle!

Thanks for answering guys.

I've a Mac 10.13.6 I did the Catalina install. As for as I could tell it just put a new IDE on my drive called Teensyduino. I'm kinda' asssuming this is all I need and...

Guys, can someone give me a quick. What is teesnyduino explanation?

Is it a replacement for the IDE? Do I still need the original Arduino IDE? From my ignorant user's point of view, everything has...

Update to above..

D-loaded fresh arduino and the new teensyduino. Mac OS 10.13.6

Same result.


Multiple libraries were found for...

Same thing. I can't compile this library. To update is the easiest thing to do just to grab a new teensyduino?


#include <Adafruit_GFX.h>
#include <ILI9341_t3.h>


void setup() {

}

Hahah! Yeah. My Ma used to read those to me when I was but a we tot. Mmmm! Soup, grilled cheese sandwich and a chapter of Whinny the Pooh. Those were the days!

The code's already on...

@grease_lighting Mine turned into pretty much a complete OS for Arduino kind of processors. (Mainly teensys) Multi sketch swapping, simple threading, a fancy file system, screen drawing, icons.. The...

I hear you on writing one's own is easier to understand than wrapping your head around someone elses's ideas. Probably why so many of us end up writing our own.

Good luck with it! It'll be...

Guys really, I think you nailed it on the head that the receive is not up to the job. I just wanted to confirm that the Serial.flush() was doing what I thought it was doing, blocking 'till it's all...

Well sure. In one end I'm sending a bunch of stuff. In the other end of the hose I'm seeing what comes out. If the hose is connected to the monitor on the development computer, I get what I expect....

On my cellphone, I had to do complete screen rewrites and some those would take over a couple seconds. Looked horrible. So I just, between refreshes, turned off the backlight, then brought it back up...

And, I'd miss MOSI & MISO. I always see them as these two Asian helpers..

Weird I know.

-jim lee

I'm having issues that I suspect may be my Serial1 is getting stopped before its sent out all of its data. I sent the output to the monitor and I get it all, send it to Serial1 and I get 63 bytes.

Starting place? I have one I've written from scratch. It runs on a few Adafruit screens at the moment. But, it may be a little too rough for outsider's use. You are welcome to have a look.

Yeah, the error messages showed I was using all teensy stuff. Hence my post here. My thought was that it was some flavor of version-itus and maybe it was a well known thing. That and I've been...

I think I got it. They have to have the files ordered in some perfect sequence or it'll not work. I stumbled on the correct sequence and now at least it runs. Although the fonts are bigger than I...

Where do you get a cable that can connect the two?

-jim lee

Tried to roll in some fonts for my Adafruit screen I'm getting this : Applications/Arduino.app/Contents/Java/hardware/teensy/avr/libraries/Adafruit_GFX/Fonts/FreeSans12pt7b.h:1:7: error: 'uint8_t'...
