NV3007 LCD Controller driver
|
||||
=============================
|
||||
|
||||
Overview
|
||||
--------
|
||||
|
||||
The `NV3007 <https://www.buydisplay.com/download/ic/NV3007.pdf>`__ is a single-chip driver for 262,144-color, a-Si TFT liquid crystal display
|
||||
with maximum resolution of 168RGBx428 dots. It contains 252-channel source driver,
|
||||
a 24-channel GIP driver which used for dual-gate control, 161,784-byte GRAM for
|
||||
graphic display data, internal precise power supply circuit which supports full color,
|
||||
8-color display mode and sleep mode
|
||||
NV3007 supports 3-/4-line serial peripheral interface (SPI) ， quad serial
|
||||
peripheral interface (QSPI). The display area can be specified in internal GRAM by
|
||||
window address function.
|
||||
|
||||
The NV3007 LCD controller `driver <https://github.com/lvgl/lvgl/tree/master/src/drivers/display/nv3007>`__ is a platform-agnostic driver, based on the `generic MIPI driver <https://github.com/lvgl/lvgl/blob/master/docs/src/details/integration/external_display_controllers/gen_mipi.rst>`__.
|
||||
It implements display initialization, supports display rotation and implements the display flush callback. The user needs to implement only two platform-specific functions to send
|
||||
a command or pixel data to the controller via SPI or parallel bus. Typically these are implemented by calling the appropriate SDK library functions on the given platform.
|
||||
|
||||
Prerequisites
|
||||
-------------
|
||||
|
||||
There are no prerequisites.
|
||||
|
||||
Configuring the driver
|
||||
----------------------
|
||||
|
||||
Enable the NV3007 driver support in lv_conf.h, by cmake compiler define or by KConfig
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
#define LV_USE_NV3007 1
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
You need to implement two platform-dependent functions:
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
/* Send short command to the LCD. This function shall wait until the transaction finishes. */
|
||||
void my_lcd_send_cmd(lv_display_t *disp, const uint8_t *cmd, size_t cmd_size, const uint8_t *param, size_t param_size)
|
||||
{
|
||||
...
|
||||
}
|
||||
|
||||
/* Send large array of pixel data to the LCD. If necessary, this function has to do the byte-swapping. This function can do the transfer in the background. */
|
||||
void my_lcd_send_color(lv_display_t *disp, const uint8_t *cmd, size_t cmd_size, uint8_t *param, size_t param_size)
|
||||
{
|
||||
...
|
||||
}
|
||||
|
||||
To create an NV3007-based display use the function
|
||||
|
||||
.. code-block:: c
|
||||
|
||||
/**
|
||||
* Create an LCD display with NV3007 driver
|
||||
* @param hor_res horizontal resolution
|
||||
* @param ver_res vertical resolution
|
||||
* @param flags default configuration settings (mirror, RGB ordering, etc.)
|
||||
* @param send_cmd platform-dependent function to send a command to the LCD controller (usually uses polling transfer)
|
||||
* @param send_color platform-dependent function to send pixel data to the LCD controller (usually uses DMA transfer: must implement a 'ready' callback)
|
||||
* @return pointer to the created display
|
||||
*/
|
||||
lv_display_t * lv_nv3007_create(uint32_t hor_res, uint32_t ver_res, lv_lcd_flag_t flags,
|
||||
lv_nv3007_send_cmd_cb_t send_cmd_cb, lv_nv3007_send_color_cb_t send_color_cb);
|
||||
|
||||
|
||||
Arduino Example
|
||||
---------------
|
||||
|
||||
Here is a simple example of using the NV3007 display with Arduino framework and SPI interface:
|
||||
|
||||
.. code-block:: cpp
|
||||
|
||||
#include <lvgl.h>

||||

||||
#define LCD_RST 4
|
||||
#define LCD_SCK 18
|
||||
#define LCD_MOSI 23
|
||||
#define LCD_MISO -1
|
||||
#define LCD_BL 15
|
||||
#define SPI_CLK 40000000
|
||||
|
||||
#define BUFFER_SIZE 142 * 50
|
||||
uint8_t buf[BUFFER_SIZE];
|
||||
|
||||
/* Define your platform-specific functions to send commands and data */
|
||||
void my_lcd_send_cmd(lv_display_t *disp, const uint8_t *cmd, size_t cmd_size, const uint8_t *param, size_t param_size)
|
||||
{
|
||||
SPI.beginTransaction(SPISettings(SPI_CLK, MSBFIRST, SPI_MODE0));
|
||||
/* Send command */
|

|

|
||||
{
|

|
||||
SPI.transferBytes(param, NULL, param_size);
|
||||
}
|

|

SPI.endTransaction();
|

}
|

/* Send the command first */
|

|

SPI.transferBytes(cmd, NULL, cmd_size);
|
||||
|

/* Then send the pixel data */
|

if (param && param_size > 0)
|

SPI.transferBytes(param, NULL, param_size);
