I want to create the firmaware on ATMEG2560 and Arduion IDE.
The firmware have to record (when a button is pressed) a sequence of commands and movements drive by the user trought a joysitck (command is 3 Analog Inputs, on 1 Analog, direction and speed informations) to controls 3 stepper motors, and stop reccording when it pressed again.
Another button lunch the sequence reccorded like a loop.
The reccording command could be store on a SD card communicate with SPI.
The hardware is Arduino mega + 3 EasyDriver v4.5 + SD Cards if you think a need to had more thing, tell me.
