- GoBadge aka Adafruit PyBadge
- Personal computer with Go 1.18/1.19 and TinyGo installed, and a serial port.
If somehow you have not installed Go on your computer already, you can download it here:
Now you are ready to install TinyGo.
Follow the instructions here for your operating system:
https://tinygo.org/getting-started/
Plug the GoBadge into your computer using a USB cable. There may be one provided in your starter kit.
Make sure that the GoBadge is on.
The TinyGo programs will run directly on the GoBadge's microcontroller. The procedure is basically:
- Edit your TinyGo program.
- Compile and flash it to your GoBadge.
- The program executes from the GoBadge. You can disconnect the GoBadge from your computer (plug it into a battery, if it isn't already), the program executes directly on the microcontroller.
Let's get started!
This tests that you can compile and flash your PyBadge with TinyGo code, by blinking the built-in LED (it's on the back).
tinygo flash -target gobadge ./step0
Once the PyBadge is flashed correctly, the built-in LED labeled "D13" (on the back) should start to turn on and off once per second. Now everything is setup correctly and you are ready to continue.
Run the code.
tinygo flash -target gobadge ./step1
When you press the START button, the built-in LED should turn on.
Challenge: See if you can modify ./step1/main.go so that the LED turns on if the SELECT button is pressed instead of the START button.
Run the code.
tinygo flash -target gobadge ./step2
The 5 neopixels should light up green and red alternatively.
Run the code.
tinygo flash -target gobadge ./step3
The 5 neopixels should light up in different colors depending on which button you press.
What happens if you press more than one button at a time?
try out ./step3b, what does it do?
After deploying it should look like this:
Run the code.
tinygo flash -target gobadge ./step4
Run the code.
tinygo flash -target gobadge ./step5/main.go
The message "Hello Gophers!" should appear on the display.
Run the code.
tinygo flash -target gobadge ./step6/main.go
The display will show some blue circle that represent that buttons on the board. When a button is pressed a ring will be shown around its corresponding circle.
Run the code.
tinygo flash -target gobadge ./step7
The display will show a bar for each X,Y,Z axis. Move the Pybadge to see it in action.
Run the code.
tinygo flash -target gobadge ./step8/main.go
Press the buttons and create your melody.
Good job in completing the basic tutorials. Now can check out the more complicated tutorials
