      Ok think I found one issue with the FontTest4 sketch. If you comment out this line (156 or so) else tft.setFontDef(); and replace with //else tft.setFontDef(); else {} no issue with rotation - draws cleanly. fontDef is defined in the ,h as...

      I am getting a little farther with the Picture viewer. I get images displayed but goes away quick.... It has to do with we were using a sort of frame buffer in the output code: The SPI code: inline void writeRect(int x, int y, int cx, int cy...

      Wrote a quick sketch for testing rotation and getPixel function as thought it might be interesting to try out. Again seems issues with rotation and may pixel cursor? 1st heres the sketch #include "Arduino.h" #include "RA8876_t3.h" #include...

      The forum's logging shows the new rules that block new user registrations from ASN 45609 are being triggered, one of them only 12 minutes ago and the other a few hours ago. Impossible to know if it's blocking legitimate new users or the same...

      Either way - Lots of activity on threads or posts for a first time sign up - not sure of the granularity the BBS offers for startup control. Some BBS's allowed required EMAIL confirm before posts and IIRC Paul didn't want to require such. The...

      Is it possible to cap the number of new threads a user can make in 24 hours? I can't really imagine any situation here where anyone would need to create >3 threads in one day.

      Sorry for the delay. I was at the Teardown conference all day. Looking at this just now... Sadly, it seems the spammers from India that plagued the old vbulletin server have returned. I had really hoped we would not need to block huge...

      @defragster thanks for the links. Unfortunately as they don't use the SAI/I2S interface, they are of no help. I made some changes - now I can get it to play until the buffer is full #include "SdFat.h" #include "Audio.h" #include "Wire.h"...
    • defragster
      Great you got playing from a buffer. Indeed, it uses some cool timing to make sound from coded values adjusting DAC type output values. Read that timing was an issue and this uses interrupts to feed it not DMA - other than that not seen anything...

      :) If there is a 'best' common feature set, then getting that working in one batch would be a good start for proof of concept. The Star interconnect should 'simply' work - but look how long sliced bread took :) Getting it wired and then...

      defragster replied to the thread Game Console with iMXRT1062.
      3 bytes times 1280 times 720 is 2.64 MB so two of those buffers fit easily in 32MB single SDRAM/VRAM as on the DevBoard design. That leaves 26.7 MB free from the 32MB - enough room for larger display or 10 more such buffers? Noted on other...

      That posted sketch is BLANK? With Serial4.begin( ??? ) at the right baud rate then pins 16 and 17 are correct if Rx on one goes to Tx and also Tx goes to Rx. GND must also be connected, and the device must be getting enough POWER to run. Are...

      defragster replied to the thread watchdog Timer for teensy 4.1.
      Interesting how this happens? Is the NoteOff missed or somehow lost? Or is there something latching the pin ON when it was commanded to drop to OFF? Watchdog is critical when the sketch can HANG somehow. Not sure there is a hang of any sort...

      IIRC @PaulStoffregen posts about the solder/flux used and it is water soluable/washable. Yes - see here: https://forum.pjrc.com/index.php?threads/new-teensy-4-0-suddenly-not-recognized.74957/post-343582

      * I am far from an expert, I've only designed a few BGA boards thus far. It's sometimes hard to route, the 5V is there because it was the easiest way. Going to a 6-layer board would make life many times easier. I just got my first 6-layer board...

      If a 15 sec Restore works it should stay with RED LED on some long time then come back to blink showing the bootloader and the 1062 are in good shape together. >> Power, Press Button and hold ~15 secs until RED LED (bootloader LED) flashes and...

      Not seen any long term 2 year runs to an SD card noted? Given it is T_4.1: One idea would be a Bottom soldered QSPI FLASH chip - 64+MB would hold 2 years of logging and could be sent to SD card daily or weekly for backup and retrieval that would...

      You might try DUAL USB for a debug on the second USB port. USB Serial typical runs well until something crashes the USB code or interrupts that service it. " Tools / USB Type: Dual Serial" USB might survive and allow Debug output? Only ever used...

      Note that the QNEthernet library supports a W5500 driver for the Teensy 4.0. It’s possible for other drivers to be written too.
    • defragster
      The QNEthernet library should support Teensy 4.0 just fine, including accessing the MAC address. I tested this. If it doesn’t, that’s a bug. I’ll explore more later today.
    • defragster
      With manual control of the pins - not the SPI hardware ? - look into setting the slew rate higher for faster rise time?

      I went into the source files and found that enet_get_mac() [ in ...\GitHub\QNEthernet\src\lwip_t41.c] and put in a sketch with edits for Print's and results are as shown. Based on Paul's CrossPost #13 - there may be an #ifdef type exclusion for...

      Just stole this code {and added printf()'s} from QNEthernet and T_4.0 returns a MAC just fine: uint8_t gmac[24]; void enet_get_mac(uint8_t *mac) { if (mac == NULL) { return; } uint32_t m1 = HW_OCOTP_MAC1; uint32_t m2 = HW_OCOTP_MAC0...

      You're right about that. I think I missed that part in the related article in post #15. I tested that with some code: struct OrderedValues{ uint32_t big1; uint32_t big2; uint16_t middle1; int16_t middle2; bool goodbad1; bool...

      defragster replied to the thread SD Card Write Speed Patterns.
      Nothing concrete - but general observation from prior notes suggest indeed the SD hardware/controller system does housekeeping with some 'regularity' that takes a larger time period, and it seems this may be what is being recorded. Was the file...

      Just to disambiguate some terms: The Teensy 4.1 has support for “native Ethernet”, meaning there’s a PHY chip on-board for interfacing with Ethernet ports. There’s also a library called “NativeEthernet” that happens to be included with the...

      Thanks Shawn. I used your QNEthernet and the Ethernet kit from PJRC, and it works a treat! I am gobsmacked at the speeds I am getting. Revolutionised my project TBH.
    • defragster
      Yes, QNEthernet retrieves the Teensy's stored MAC.
    • defragster
      It's OK, no need to "mark as solver", you just have.
