MicroBit Project #09 for INF 294

Project description:

Using code for MicroBit built in C/C++, send a message via radio TX that displays A when button A is pressed and B when button B is pressed. A second board receives the message and displays the corresponding character.

I used the MakeCode editor to test the algorithm in the MicroBit framework, then wrote the code in the mbed compiler to create the HEX file and test the program. I also edited the MicroBitConfig.h file to disable BLE so the radio could be enabled.

Following is the JavaScript that corresponds to the blocks in makeCode. This serves as a pretty good algorithm when the image of the blocks cannot be viewed.

input.onButtonPressed(Button.A, function () {
    radio.sendString("A")
    basic.showString("A")
    basic.pause(500)
    basic.clearScreen()
})
input.onButtonPressed(Button.B, function () {
    radio.sendString("B")
    basic.showString("B")
    basic.pause(500)
    basic.clearScreen()
})
radio.onReceivedString(function (receivedString) {
    basic.showString(receivedString)
    basic.pause(500)
    basic.clearScreen()
})
