## Installation
```
cd
mkdir components
cd components
git clone https://github.com/VedantParanjape/esp-epaper-display.git epaper
```
Change CMakeList.txt to add the line given below:
`set(EXTRA_COMPONENT_DIRS )`
component folder must contain `epaper` component
## Configuration
Set the pins used and appropriate display module used in menuconfig
```bash
idf.py menuconfig
```
Setting present at: `Component config --> E-Paper display configuration`
#### Pin setting
Path: `Component config --> E-Paper display configuration`
#### Display model setting
Path: `Component config --> E-Paper display configuration --> Display Type`
## Example code
Example app: https://github.com/VedantParanjape/esp-component-examples/tree/master/esp-epaper-example
```c
#include "epaper.h"
#include "esp_log.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "driver/timer.h"
#define COLORED 0
#define UNCOLORED 1
extern "C" void app_main()
{
Epd epd;
unsigned char* frame_ = (unsigned char*)malloc(epd.width * epd.height / 8);
Paint paint_(frame_, epd.width, epd.height);
paint_.Clear(UNCOLORED);
ESP_LOGI("EPD", "e-Paper init and clear");
epd.LDirInit();
epd.Clear();
vTaskDelay(2000);
int d = 3;
for (char i = '0'; i <= '9'; i++)
{
paint_.DrawCharAt(d, d, i, &Font20, COLORED);
epd.DisplayPart(frame_);
vTaskDelay(100);
d = d + 20;
}
epd.Sleep();
}
```
