RK043FN02H-CT Parallel Display
|
||||
##############################
|
||||
|
||||
Overview
|
||||
********
|
||||
|
||||
RK043FN02H-CT is a 4.3 inch TFT 480*272 pixels with LED backlight and
|
||||
capacitive touch panel from Rocktech. This LCD panel can work with several i.MX
|
||||
RT EVKs and LPC MCUs for evaluation of applications with display.
|
||||
|
||||
More information about the shield can be found at the `RK043FN02H-CT product
|
||||
page`_.
|
||||
|
||||
This display uses a 40 pin parallel FPC interface plus 6 pin I2C interface,
|
||||
available on many NXP EVKs. Note that this parallel FPC interface is not
|
||||
compatible with the MIPI FPC interface present on other NXP EVKs.

Requirements
|
||||
************
|
||||
|
||||
This shield can only be used with a board which provides a configuration
|
||||
for the 40+6 pin parallel/I2C FPC interface
|
||||
|
||||
Programming
|
||||
***********
|
||||
|
||||
Set ``-DSHIELD=rk043fn02h_ct`` when you invoke ``west build``. For
|
||||
example:

||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/drivers/display
|
||||
:board: mimxrt1060_evk
|
