I don't have a video of my own railroad, because it is still under construction. Most of the usage to date has been on contract jobs with custom layout builders. I will work on getting a video of one of those layouts, but I am hoping to develop an instructional video in the near future that...

This project, originally developed for signaling and control systems for model railroads, can actually be used for almost any kind of control or lighting project. It features 8 inputs and 16 powered outputs, as well as two network connections to add up to 50 expansion boards. A simple...

Thanks for that suggestion... It turned out you have to set the DTR (Data Terminal Ready) line ON before the PC will connect to the Teensy. Who knew... Anyway, all seems OK now.

This is written in POWERBASIC and EZ_GUI but is basically similar to VB. I extracted a bit of the code, because the whole program is 7000 lines, most of which are not of any interest. LOCAL BYTES_REPLY AS LONG LOCAL REPLY_MSG AS STRING COM_HANDLE = FREEFILE COM_PORT =...

Is there any secret to sending/receiving data from the PC via the USB connection to the Teensy (4.1) ?? Here's my setup: I have a PC program that I want to communicate with the teensy over the USB serial port. The teensy is opening the Serial connection on its side and waiting for a message...

Is there support and/or examples of using the backside flash/psram memory on the Teensy 4.1? Or a list of what the Auduino pin number are for the memories. I'm new to this and not sure how to map the pins on the schematic to the Arduino "pin" numbers. I need to add a chunk of flash to the 4.1...

Thanks! That seems to have fixed the issue. Chuck

Beginning just yesterday, my Arduino compiler will no longer run - it just shows the splash screen and then crashes. I read on the Arduino forum that there is a new overnight build that gets around this problem, but after I installed it, I can't install Teensyduino. Apparently they are not...

That would be OK in my app - once it is programmed, it won't be reprogrammed by the user, but I'd like to let them load configuration data into the unused flash area. I can add an external flash chip, but I figured since all this memory is sitting there, it would be nice to use it.....

I see that the new Teensy 4.0 has 2 M of flash memory, but the system RAM is 1 M, and I'm never likely to have my program grow that large. Can I use a portion of the flash memory to store information that is needed by the program? I don't need a real file system, just a way to store and...

Can someone tell me what the proper connection is for the power pushbutton on the 4.0? I assume it is a normally open with a connect to ground when closed, but I can't actually find anywhere this is documented, and I hate assuming....
