Is there a way to configure the Aurdino IDE to look for the teensy library source in a different place? I want to hack on usb_desc.h, usb_desc.c, and usb_dev.c and I'd like to put my changes under version control. I'd...
Maybe this has been a known issue for at least 9 years: https://answers.microsoft.com/en-us/windows/forum/windows_xp-hardware/virtual-serial-port-usbsersys-is-not-sending/a086cbf6-2d0a-4c46-88fd-73865bc185f5
Thank you for your time and attention. I really appreciate it. I like that protocol analyzer.
And you answered my question: there is no custom driver. Maybe the bug is in the Windows driver. Any maybe all the...
There is a collection of ham radio apps that use RTS to key a transmitter. These all work with standard USB to serial port adapters like the FTDI. Of the four apps I tried, only one works to set RTS on the Teensy. Maybe...
I just did a quick google and found this: https://github.com/PaulStoffregen/cores/blob/master/teensy3/usb_serial.h and I can't help wonder if
operator bool() { return usb_configuration &&...
I should add that it's not *just* Termite that is doing something weird. I have several other programs that use RTS as a signal, and they all function fine using other USB-to-serial adapters but not with the Teensy.
Here's more interesting behavior using Termite:
DTR can be ON or OFF as its initial state.
Turn RTS ON. Teensy does not see the RTS state change to ON.
Toggle DTR. Teensy now sees the RTS state change to ON....
Interestingly, RTS works as expected with CoolTerm. It must be something with how the COM port is initialized by the Windows programs. So far, I have 2 programs where RTS works as expected, and 3 where it doesn't. Maybe...
I am trying to use Serial.rts() as a signal from a Windows program to teensy code, like this:
const int LEDpin = 13;
void setup() {
Serial.begin(9600);
pinMode(LEDpin, OUTPUT);
digitalWrite(LEDpin, LOW);...
