[RTL8722CSM] [RTL8722DM] GPIO - Blink
Materials
AmebaD[AMB21 / AMB22] x 1
LED x 1
Resistor(220ohm) x 1
Steps
Blink is one of the best ambd_micropython/examples to get started with MicroPython.
Let us connect pin PB_22 to the anode leg of an LED which in series with a current limiting resistor and GND to cathode of the LED as shown below,
Then, copy the following code and press Ctrl + e
in REPL
to enter the paste mode (for more information about REPL
and paste mode, check “Getting Started” page). If you are using Tera Term
, simply right click on any blank space of the terminal and paste the code into REPL
, then press Ctrl + d
to execute the code. If everything is order, you should be able to see the LED blink for 3 times in 3 seconds.
