Computer to microbit connection with Small Basic.
You can write a simple GUI to send commands to a microbit running Python:
The program sends Python commands over a serial connection to the microbit. I’ve kept it as simple as possible so you can customise it further.
Clicking PIN0 High sends the command
pin0.write_digital(1) to the microbit. You could type
display.show(Image.HAPPY) and click Send Command would show a smiley on the microbit.
Flash a Python program to the microbit. You can just flash an empty program from within mu.
Install the lit dev extensions for Small Basic. These are used to communicate over a serial connection.
Find out the COM port of your microbit.
Add your COM port at the top of the Small Basic code.
comPort = "COM4" Initialise() While ("True") Program.Delay(10) EndWhile Sub Initialise 'draw window' GraphicsWindow.Width = 500 GraphicsWindow.Height = 100 GraphicsWindow.Title = "Small Basic Microbit Controller" 'draw pin control buttons' pin0high = Controls.AddButton("PIN0 High", 20, 10) pin0low = Controls.AddButton("PIN0 Low", 100, 10) 'draw status and command buttons & boxes' statusbox = Controls.AddTextBox(20,50) value = Controls.AddTextBox(210,13) send = Controls.AddButton("Send Command", 380, 10) 'Open connection to microbit' Controls.SetTextBoxText(statusbox,"Status : "+ LDCommPort.OpenPort(comPort, 9600)) 'Assign variables' Controls.ButtonClicked = OnButtonClicked nl = Text.GetCharacter(10) 'new line character' EndSub Sub OnButtonClicked button = Controls.LastClickedButton val = Controls.GetTextBoxText(value) 'if button pressed, send command and new line character' If (button = pin0high) Then LDCommPort.TXString("pin0.write_digital(1)+nl") ElseIf (button = pin0low) Then LDCommPort.TXString("pin0.write_digital(0)+n1") EndIf If (button = send) And (val <> "") Then LDCommPort.TXString(val+nl) EndIf EndSub
