How do I open a bi-directional terminal for IoT Basic?

[twoporylyj]

Describe the bug When I compile and run Stefan's IoT Basic, i get only an unidirectional terminal, which is not interactive, and I cannot tell the Basic interpreter to do something, all I get is a startup prompt...

To Reproduce Open a blank page with e.g. Nano in the emulator. Remove file with default sketch. Upload all these four files into the emulator from here: https://github.com/slviajero/tinybasic/tree/main/TinybasicArduino Start emulation and wait for terminal to appear.

Expected behavior Bi-directional terminal instead of unidirectional one. Ability to communicate with Basic interpreter beyond the startup prompt.

Environment (please complete the following information): Chromium based browser on Android 9

Additional context None

You can change the Serial Monitor into a Serial Terminal by setting the display mode to "terminal" in diagram.json:

  "serialMonitor": { "display": "terminal" }

Here is a complete example (which you can also use as a starting point):

Good luck running IoT Basic! Please do share the project on our discord community. There's a #projects channel for sharing.

Thanks, it was so simple!

You're welcome :-)

To all experimenters, if you still experience problems after this change (interpreter does not respond to what user types), take hardware-arduino.h file, find there the following line:

undef USESPICOSERIAL

And change it as shown below:

define USESPICOSERIAL

And everything becomes excellent. I am planning to perform some experiments with HD44780 compatible display controlled from this Basic both on emulator and real hardware. Nothing complicated, really. Found how to use the display and what else to define here: https://create.arduino.cc/projecthub/sl001/basic-on-arduinos-5b4e24 And which pins are used as standard on such shields: https://arduinomaster.ru/platy-arduino/arduino-lcd-keypad-shield/ Connected the display (only virtual for now) accordingly, tried to control it by using print &2, and... success!

Just programmed an example. Four spaces before each line are required to correctly automatically paste text with line numbers from Android clipboard to Javascript terminal. 10 pinm 2,2 20 pinm 3,2 30 pinm 11,2 35 pinm 12,2 40 print &2,dread(2); 50 print &2,dread(3); 60 print &2,dread(11); 70 print &2 80 delay 100 75 if dread(12)=0 goto 100 90 goto 40 100 print &2, "Stopped" 110 stop This program simulates behaviour of some PLCs which display state of all inputs on LCD. In this case, there are four pulled-up inputs connected to buttons. State of three of them is displayed on the HD44780 compatible display. When none is pressed, there is 111. If you push one of the buttons, its state changes to 0. Like this: 011. Multitouch is supported by the emulator, i tried to push all three buttons simultaneously, and it works. The fourth button stops the program with displaying "Stopped".
