I am doing a lib to control ILI9341 Display and in order to send command or data i need to control two CS lines.
I am able to define and assert two CS with no problem, but i am not able to deassert only one. even when i write TXDAta plus CTRL the second CS would not go low.
the only way i am able to deassert is sending EOT + EOF but in this case both lines would go high again.
Does any one knows how to do that using this microcontroller?
thank you very much.
