currently most of the graphics blocks do not work directly with the stick yet without some modification.
For instance you can use the lcd.line and lcd.rect blocks in graphics but the hex value for colour needs to be removed from the code since the OLED is a monochrome display.
lcd.line(5, 5, 3, 3)
lcd.rect(8, 8, 10, 10)
For displaying text the lcd.text function is used. There is no blocks for this as of yet but you can type
lcd.text(x value, y value) which I think is limited to 8 characters per line.
The speaker blocks work without modification, and most of the units should be able to interface normally
with the stick on port A, I'm still testing so I cannot 100% confirm this.
The Led can also be controlled with the digital write blocks in the Pin section
Hope this helps
