pico is raspberry pi's micro controller Chirstened RP2040. It is an arm cortex 0(2 cores) micro controller.
this is meant to be a toy project. It will allow you to turn on the onboard led of pico.
You need to plugin the pico into your usb port, and install a serial communication program,
I have tested this with minicom, send the character j for a dash(long duration led blink),
any other key will be a dot(short duration blink).
-
To compile download arm-eab-none-gcc, keep the binary folder(of this compiler) in your path.
-
Clone this repository, and make build directory
-
cd into the build directory and use
- cmake and
- make
-
move the .uf2 file to your rpi2040
-
use minicom to connect to rpi with serial communication.
-
type
j, and you will see led turn on for 200 ms -
any other char and you will see it turn on for 10 ms
go run serial_write.go, is a program to write serial
