By default, it downloads the indexes each time you start the IDE where the delta time is > timeout from the last download. It does not take 5 minutes to download the Teensy, it simply does not update the message from downloading the last index...

I have this problem too... but mine doesn't complete in 5 min. I found some guidance in an Arduino forum thread once to back-level Arduino IDE to 2.0.something to fix, but I just switch my selected board in Arduino IDE to COM3, which forces the...

Why does Arduino repeatedly need to download the " package_teensy_index_json " If this index is only about 20K , why does it take 5 minutes to update in Arduino?

As this part of the forum isn't that busy, I'll post an update. Inspired by PositionHigh and other legends I made a remote UI application using webSerial. This was actually very easy since I already have a "display module" that communicates with...

Time to satisfy your retro cravings! I revisited this old project recently and did some well needed updates. It is a polysynth based on (real) commodore SID's. It accepts up to four of them and supports both 8580 and 6581 variants. Control is...

Ok. I guess that blows my bad assumption that all UARTs are created equal. :) Correct, I am looking for high refresh rates of large LED displays (ie- cubes) from non-blocking writes to all 7 Serials in parallel (interleaved). On Teensy 4, I...

In 7N1, I send 8-bit data with Serial1.write() but only the low 7 are significant. Serial hardware strips the high bit, then adds 1 start and 1 stop bit. The bytes I write are designed for the start/stop bits to result in a 9-bit 7N1 packet...

Thanks, but I really need 7N1 for my app, and I was hoping to extend my app compatibility to Teensy 3.x. My app is an LED display driver, and 3 bits is a 'magic' number for LED input. Only true 7N1 lets me use 3 serial bits to pattern one LED...

As MarkT already pointed out, that MOSFET is a 5V logical compatible device and not meant to work with 3.3V. It is barely turning on if being driven directly by the Teensy so it would be acting like a large resistor rather than a switch...

I've snooped through the megamanual and can't find any reference to 7 bit mode (aka M7 flag on Teensy 4.x) or how to achieve 7N1 format on the 3.x hardware serial ports. I was wondering if anyone had knowledge/experience with this. For 7N1 on...
