Stepper moter code

I had an experience to fail running stepper moter with c programming so I use .

Test touch sensor and output with I2C

 

16 key touch sensor and LCD display code

we are useing 2004 LCD with i2c/SPI character LCD backpack and TTP229 capacitive touch sensor. First I tested individuar board. LCD and TTP229 works well.



-check datasheet for TTP229. Option stats '1' means defalt. '0' needs to solder/jumper.

When I connected '2004 LCD with i2c/SPI character LCD backpack' and 'TTP229 capacitive touch sensor' at one Uno board, it did not work.
I put common SDA in A4, SCL in A5. but the board did not work.



I run I2C address scanning code to know exact address of each board.
-LCD with I2C can get its address exactly. but TTP229 changed whenever I did and sometimes did not show up at all.


-it was hard to find a exact address of each board. So I decied to use 2 arduinouno board. But it did not work again.

-Due to lack of time, I changed the button to 4x4 Matrix Keypad. and it works well.

Motor control with RAMPS.

Setup all funtions for ready.

-On arduino mega board with RAMPS, I set up keypad, LCD, 4 step motors to run.

Native Programming.

Last Coding works with YoungSik. First, we discuss about the programming process. Then check with the mechanicla part step by step.
