      Decided to hold off on that for now... Did lay out quick and dirty semi-shield for the Sparkfun ATP board Slight downside is that two Teensy pnis are not available (22, 28), but... The only real components to solder in are the SDIO connector and...

      @WA2MZG - At one point I was having the same problem when I was adding the use of USB host drives. I started experimenting with different buffer sizes in the mp3 player code: #define MP3_SD_BUF_SIZE 2048 This is found in FrankB's...

      Yes, they have very good customer service. They kept in contact with me the whole time letting me know what was going on. All in all a confidence booster :D Thanks for your input... Edit: If anybody has a need or want for something like this I...

      @KurtE - Is this the same board that you had made that supported the BuyDisplay 10.1" LCD? The display can be configured to use the 8080 interface and I know the MMod can be configured for 8080. I would be interested in one of these boards if all...

      I want to thank everybody for the advice given. I chose OSHPark. Everything worked out without any problems. I just received my 3 boards and populated one of them (barely, shakey). Hooked it up and it works:D Thanks again for the help.

      @luni - I have been playing around with the CallBackHelper library. Trying to learn something :D. One problem I ran into was a capitalization error in "PIT.h": #include "callbackHelper.h" Should be: #include "CallbackHelper.h" I use Linux which...

      Great success! Swapped the color order on the pins, so its wired B0-7, G0-7, R0-7 on LCD_DATA0 through LCD_DATA23 pins and it looks great! So that confirms the color order on the eLCDIF output is BGR and not RGB

      Just so everyone understands. What Rezo is doing above, will in the end result in a library for anyone to use. I think it will add allot of value to the Teensy platform. SDRAM + eLCD = great success! ;) @Rezo and @jmarsh, good work! :D

      Here's a quick update from me: Got some 5" and 4.3" LCDs here, 800*480px, 16.7M colors @Dogbone06 sent over some Adaftuit 40 pin lcd breakout boards which arrived on Monday, got to wiring it up day before last, and started testing. Consulted...

      I tried this on Linux first and it minimized the IDE window. Then I selected 'Export Binary' from the sketch folder and it succeeded. Then I tried it in windows and a info window for my HP Pavilion popped up. I was able to disable that popup and...

      wwatson replied to the thread Teensyduino 1.59 Beta #6.
      I played with this a bit and I think I have it figured out what it actually does. Let's say I have A GIGA R1 plugged in and have it selected. Then unplug the GIGA R1 and plug in a T4.1 then click on the info button and hover the mouse over the...

      wwatson replied to the thread ReadWrite files to SD card.
      If I understand you correctly you are trying to upload two separate sketches into the T4.1 to be used together? If that is the case then it's not going to work. The second sketch will overwrite the first sketch. Every time you upload a sketch...

      wwatson replied to the thread Teensy 4.1 or Arduino GIGA R1.
      I have the display but not the camera. It seems to work ok and has a couple of 3D animations as demos. One thing to be careful of is the pin labels on the GIGA don't match the pin labels on the display and the connectors are not keyed. Here is a...

      I thought I would give a quick update. I am still working on having it use multiple shifters. But yesterday decided to go back to basics of using 1 shifter and figure out why it is not working. And finally I believe it is working with 1 :D...

      Added a mandelbrot sample that cycles the palette colors (still using only 4bpp/16 colors because it turns out I only have RAMDACs on hand, not direct VGA DACs...) A picture of 1920x1080 output for @Dogbone06 :

      Thanks for the input. 14 resistors, 1 PCB mount female VGA connector and an edge connector probably does not constitute a 2x2 " board :D

      Thanks everybody for the advice. I did go with OSHPark. It was a little over 18 bucks for three boards and free shipping. The board is about 2x2 inches. This was my first attempt doing a board layout and it probably could be laid out better. Will...

      Looks like there is some good news... I have (very basic) LCDIF code running and it is able to push 1024x768x60@8bpp (dual-buffered) without any problems... and can even manage 1280x1024x60Hz if the SDRAM is overclocked to 200MHz. I'm not exactly...

      Make sure the sample rate of the ripped mp3 files is at 44100 rate. I ran into this when converting wav files to mp3 files. I am not sure if @FrankB's library supports the 480000 sample rate. Other members might have more input here.

      Maybe this will work?

      Hi @KurtE, I definitely had it working with Ubuntu 22.04 and it seems to me that I had finally got it to work with W11. I have not been in W11 for a while but I will check and see if Mbed CE is still installed. Hopefully I wrote down the...

      I also have been playing with a GIGA and can vouch for what KurtE is saying. They use Arduino-Mbed-os which is still developing. Makes me appreciate Teensy's a lot more and the hard work everybody has put into them.

      Sorry, I misremembered- this was the post https://forum.pjrc.com/threads/28037-Teensy-3-1-and-K20-FlexTimer-config-for-FreqMeasure but apparently I was doing frequency, not pulse width.

      @mborgerson - I played with this today and came up with a not so glorious workaround. I broke up the 128KB into smaller chunks of varying sizes like 16KB, 32KB and 64KB. I created another transfer buffer in DTCM that I could memcpy size_t chunks...
