c23b7ec93d From Lorenz Meier: The implementation of access() as vararg macro has the issue that any function call with the same name (even in a C++ class) will match with it and result in a compile error. I have replaced it with a small function, and tried to have decent documentation as well. This resolves the compile issue, and shouldn’t have negative side effects for users of the function. 2014-11-11 11:52:24 -06:00

f8c4c75c17 include: adds interface description for ili9341
This adds the description of the generic interface to communicate with
the ili9341 lcd single chip driver used by any displays.

The interface have to be implemented by the platform specific subdriver.
The following functions must be exported:

-select
 Select the spi device before starting an operations.

-deselect
 Deselect the spi device after operations finished and if the device was
 selected before.

-sendcmd
 Send any command to the ili9341 display driver.

-sendparam
 Send any parameter corresponding to the ili9341 display driver.

-recvparam
 Receive any parameter from the ili9341 display driver. This is only possible
 for the read commands supported by the ili9341.

-sendgram
 Send pixel data to the gram of the display. This i similar to the function
 sendparam, but pixel data operations needs another handling of how to send the
 data to the display.

-recvgram
 Receive pixel data to the gram of the display. This i similar to the function
 recvparam, but pixel data operations needs another handling of how to receive
 the data from the display.

-backlight
 Change the backlight level of the display.

64ab35b399 There used to be two ways to pass parameters to new tasks, depending upon the configuration: Either (1) argv[] as created as an array with each string strdup'ed. Or (1) argv[] array and strings were created on the stack before the new task was started. Now, there is only one way, way (1). Way (2) might be slightly more compact, but this is not worth carry the complexity of two different ways of doing the same thing. 2014-09-01 15:39:34 -06:00
