@gigapod - Glad to see your interest in this project. A little background information and the state of the project at this moment. The WIFI card we used for testing was setup for WIFI only W/O Bluetooth being broken out. That may have changed...

HI All - First - this is a awesome project with great results. Not the easiest hardware/software problems to solve! We were contacted recently by @Dogbone06 about this project and if SparkFun would be interested. Our answer is absolutely...

Today I explored a more artistic way of visualizing the solver data. Since the velocity field is already being calculated internally anyway, I reused it as a brightness mask for the final render output. Add a bit of saturation and brightness...

Hi guys, I’m not sure whether you enjoy these updates or find them a bit too frequent. But I’m sharing them because feedback from potential users — and even silent lurkers — genuinely helps shape the project. It tells me what to improve, which...

This is the level shifter I used (but from AliExpress) and while I can read packages, Its not sending them nicely But, I did get the components today to build out a logic level shifter based on the 75HC245, but the pullups were wired...

I think I sent you the one with the SDcard connector, allows you to use SDHC1 via the SDcard slot on a T41 instead of wiring SDHC2 to pins. Just needs one wire in the header to a pin for sleep, IIRC. That's the device I used to get the first one...

Always glad to hear of folks using FlasherX. I really should release it as a proper library and deal with these few nagging issues. If your program is not very large, set reserve to 64 sectors (same as 4.1) which will be more than enough. I’ll...

@joepasquariello Thanks for FlasherX! Works like a charm. Just got it working to flash a Teensy 4.0 via ESP32-S3 Wifi / UART to T4.0. I use EEPROM on the T4.0, so got burned by the same issue of being informed there was not enough buffer space in...

If you are using EEPROM, you must set the value of FLASH_RESERVE_HI in FlashTxx.h to 256KB (64 sectors) as shown below. This tells FlasherX that the buffer must be below EEPROM. #elif defined(__IMXRT1062__) && defined(ARDUINO_TEENSY41) #define...

I had a version of this board that plugged into the SDcard slot on the T4.1. I can't recall correctly, but I think the INT GPIO might be optional, so that setup would only require a single additional GPIO pin, although obviously you can't insert...

Yes, @KurtE pulled DOCS and wrote code for 2nd SDIO usage as noted in p#79 - available WiFi chips are no longer SPI but SDIO. An adapter placed into the SDIO SD card socket could also be used.

Meant port pins, but it is 4 of them, while there seem to be 8 port pins blocked in the picture above. Of course this is my very personal opinion, and this is not at all my project. I only chimed in, because I have been one of those, who voted...

SDIO has 6 pins - 4 data line, a clock line and a command line. Two additional GPIOs are needed to control the sleep state and an interrupt trigger. IIRC, the murata chip variant that was used for this project does not support SPI. Those that do...

From all the posts the recent day here, I'm very happy the project is alive again. Very well done!!! :D:D:D:D

Must have added SER_WHITE to the colors and forgot to add it to the "blank" section Colored messages make it so much easier to "scan" console logs, even simply making error logging red means you see it at a glance rather than hunting, and with...

Just comment out line 81 in misc_defs.h, and they'll not appear, no need for extensive code changes #define USE_DEBUG_COLORS

Thanks for sharing @beermat. You weren't kidding about kitchen sink app! Quite the snappy graphics, is that the 7" RA8889 from BuyDisplay? Besides CPU clock, it looks like you are pushing all the boundaries. I don't think I have successfully...

Hahahah, thanks, it started as an essential app (the lightning trigger part) and I just kept adding and adding less and less useful stuff until it eventually just became a catch-all as I had built so much infrastructure for everything :) Screen...
