SimpleBlink

Simple Blink

It blinks a LED connected to the PIN 4 via a resistor. For uploading binaries I use USBasp programmer which supports TPI (Tiny Programming Interface) and SPI (Serial Peripheral Interface).

TIP: How to program AVR microcontrollers in Visual Studio Code

Supported microcontrollers

ATtiny4, ATtiny5, ATtiny9, ATtiny10, ATtiny20 and ATtiny40.

How to compile and upload it to a microcontroller

Option 1

In Visual Studio Code just press Ctrl+Shift+B and it compiles the code and uploads it to a microcontroller. For correct intellisense in Visual Studio Code don't forget to change c_cpp_properties.json to your target microcontroller.

"defines": [
                "__AVR_ATtiny10__"
            ], 

Option 2

By default for ATtiny10, F_CPU=1000000UL.

make

Option 3

For any other microcontrollers.

make MCU=attiny20 F_CPU=8000000UL

Option 4

avr-gcc simple_blink.c -mmcu=attiny4 -DF_CPU=1000000UL -Os -o simple_blink.bin
avrdude -c usbasp -p attiny4 -U simple_blink.bin
