Yep, I got eventually to know Processing for Arduino projects.
The board is maple mini with STM32 chip.
The lcd is the 0.96" OLED display that is 128x64 pixels.
The reason for this is that using the hardware and software of debugging the code and uploading it to the maple mini is ok.
But I liked the idea of doing the same process of outputting pixels with similar coding.
I can choose the resolution that fit any LCD I can find on the market.
So for example in places; like, in airport where I wanted to do some programming with microcontroller graphics without taking the hardware out of my bag and connect the cables and put the stuff aside and start programming.
Now, I only have to open my laptop and do my programming directly and simulate the lcd output with processing output window.
