      Sorry been long time since I did much with these displays. Most of this should work the same way as our other drivers... It may depend on what you mean by size. That is not every character has the width and the like: Most are proportional...

      Me too. But it was in his first line, which my eyes missed on the first readings.

      It runs on mine, using recent nightly build and current Teensyduino... Using library ILI9341_t3 at version 1.0 in folder: C:\Users\kurte\AppData\Local\Arduino15\packages\teensy\hardware\avr\1.59.0\libraries\ILI9341_t3 However I edited to my...

      Yep - but I also played with the beta releases 😆 Believe me, I know the feeling! Actually mine is set up to use the Windows Terminal, which I like a lot better!
    • KurtE
      Newer versions of Windows? Like maybe only the last 30 years :LOL: Maybe longer... I am guessing that a large percentage of users on Windows (and probably MAC) almost never have used a command line. So, things like Folders are a lot easier to...

      Just received the sdram development board today:D I ran through all of the test programs that I know about without a problem. I need to make sure I have all of the pinout info for this board. It is a version 4 board. I thought I would start out...

      Sorry did not have time today to fully diagnose the issue. But I dos see some issues with the code, although I would think you would still see something. int buffer0[100]; int buffer1[100]; int buffer2[100]; int rxdNum[1]; int rxd1Num[1]; int...

      KurtE replied to the thread Multiple SPI at the same time.
      Couple of different ways: For example: several of our display drivers have code built into them to allow them to do asynchronous updates. Like my ili9341_t3n library as well as others for ST7735 and ST7789, and ILI9488_t3n library. In these...

      What happens if you change: ILI9488_t3 screen = *new ILI9488_t3(CS_PIN, DC_PIN, RST_PIN, MOSI_PIN, SCK_PIN, MISO_PIN); to simply: ILI9488_t3 screen(CS_PIN, DC_PIN, RST_PIN, MOSI_PIN, SCK_PIN, MISO_PIN); And not create it using the new operator...

      It may well be a worn-out or low quality breadboard. Breadboards vary a lot in quality. A lot of chinese breadboards are very cheap but low quality - you get what you pay for! Two brands stand out: 1. BPS [BusBoard Prototype Systems]. I have...

      Sorry, again at least for me it is really hard to tell. The only thing that Arduino 1.0.5 tells me, was it was done a long time ago. A more meaningful indicator might be what version of Teensyduino, but not by much. The USB types are part of the...
    • KurtE
      Sorry, I am pretty sure there will likely not be support to run on Arduino 1.0.5 with any version of Teensyduino that supports the Teensy 4.x boards. Sorry. I personally have no idea what the Real Time System Custom USB is or was? Maybe others...

      Should work
    • KurtE
      It would probably be a good thing to do. But not sure how many sketches would be hit that include both SD.h and SdFat.h... But would probably be worth a try.
    • KurtE
      Again not much one can do, without more code, but one thing I noticed: void PlayMode::myNoteOn(byte channel, byte note, byte velocity) { if (synth != nullptr) { synth->oscPlay(40); } } void PlayMode::myNoteOff(byte channel, byte...

      Microsoft windows, complained twice as mentioned. Then Norton ran on it and said something like, scanned, ... But I think there is a bug in it: C:\Users\kurte\Downloads>hello3 Hello Defragster As I am not Defragster 😉
    • KurtE
      The one main complication you might run into, is what if you wish to build some sketches for other Arduinos that use SdFat. They will not find the libraries that are installed within the Teensy Board installs. If you install the normal...

    • KurtE
      Sorry for the delay in getting back to you. My guess is that it has a different PID/VID than the one I am using or that is covered in the library. Trying to remember how to sort it out. Lets see if we can figure it out though. First you...

      I know the USB Host code can tell keyboards the logical state of these through the LEDS( code, which sends out a control packet: driver_[0]->sendControlPacket(0x21, 9, 0x200, 0, sizeof(leds_.byte), (void*) &leds_.byte); Not sure if we listen to...
    • KurtE
      In the case of the ATP, I believe that this is due to the Voltage Regulator they choose for the board. AP7361C states: Wide Input Voltage Range: 2.2V – 6.0V And yes if you build your own board, with different VR or DC to DC converter, you can...

      The MicroMod is working with the ER-TFTM101-1 display. Still have to get the DMA portion working on the MicroMod. The images were produced in 8-bit mode none DMA, 100ms to display both pictures. I'm sure DMA will speed things up. By the time...
    • KurtE
      Not sure, but most of their carrier boards, have something like: That is from their ATP board schematic. As for AREF, don't see that on their stuff. With Teensy it is probably geared more to the 3.3v pin. I don't believe raw VIN is passed to...

      Note for things like this, I end up using sketcth that @defragster and I played with a long while ago: It sets all of the pins into either INPUT_PULLUP or INPUT_PULLDOWN. You can then take a jumper wire from either GND or 3.3v depending on...
    • KurtE
      Funy you should mention it... I believe one or more of the pages has the ATP pins on them as well... I just so happens, as I mentioned up on the thread about fancy memory :lol: I decided to make a quick and dirty shield for the ATP board, which...

      KurtE replied to the thread Compilation errors in this sketch.
      I believe that you need to update the USB descriptor to have JOYSTICK_SIZE=64, which then gives you things like: #elif JOYSTICK_SIZE == 64 void button(unsigned int num, bool val) { if (--num >= 128) return; uint32_t *p =...

      Hopefully some others might know parts of this better than I do. If you were saying a Teensy 4.1 with one of the versions of the WW35Q64 that is supported that can be soldered to the bottom of the T4.1, I would say that you could have a littleFS...

      Mouse objects depend on HID Parser objects. Have you tried the example sketches like: Mouse? Maybe try: #include "USBHost_t36.h" USBHost usb_host; MouseController mouse(usb_host); USBHIDParser hid1(myusb); USBHIDParser hid2(myusb); void...

      If you look at the T4.1 card, it is pretty easy to hook up both USB Host and USB Device. The Device pins duplicate what is in the USB connector that you connect up to your PC. So yes you can connect up the keyboard to the teensy using the...
