# ESP LCD ILI9341
|
||||
|
||||
[](https://components.espressif.com/components/espressif/esp_lcd_ili9341)
|
||||
|
||||
Implementation of the ILI9341 LCD controller with esp_lcd component.
|
||||
|
||||
| LCD controller | Communication interface | Component name | Link to datasheet |
|
||||
| :------------: | :---------------------: | :------------: | :---------------: |
|
||||
| ILI9341 | SPI | esp_lcd_ili9341 | [Specification](https://cdn-shop.adafruit.com/datasheets/ILI9341.pdf) |
|
||||
|
||||
## Add to project
|
||||
|
||||
Packages from this repository are uploaded to [Espressif's component service](https://components.espressif.com/).
|
||||
You can add them to your project via `idf.py add-dependency`, e.g.
|
||||
|
||||
```bash
|
||||
idf.py add-dependency "espressif/esp_lcd_ili9341^2.0.0"
|
||||
```
|
||||
|
||||
Alternatively, you can create `idf_component.yml`. More is in [Espressif's documentation](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-component-manager.html).

wherever such third-party notices normally appear. The contents

notices within Derivative Works that You distribute, alongside

or as an addendum to the NOTICE text from the Work, provided
|

that such additional attribution notices cannot be construed
|

as modifying the License.
|

|

You may add Your own copyright statement to Your modifications and
|

may provide additional or different license terms and conditions
|

for use, reproduction, or distribution of Your modifications, or

for any such Derivative Works as a whole, provided Your use,

reproduction, and distribution of the Work otherwise complies with

the conditions stated in this License.
|

|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of

this License, without any additional terms or conditions.
|

Notwithstanding the above, nothing herein shall supersede or modify

with Licensor regarding such Contributions.
|

|

6. Trademarks. This License does not grant permission to use the trade

7. Disclaimer of Warranty. Unless required by applicable law or

agreed to in writing, Licensor provides the Work (and each

Contributor provides its Contributions) on an "AS IS" BASIS,

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

implied, including, without limitation, any warranties or conditions
|

of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

appropriateness of using or redistributing the Work and assume any
|

risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
