## Connection

This connection method uses a 595 shift register. For AVR MCUs, you need to connect the CLK, DATA, and LATCH pins to SCK, MOSI, and SS respectively. Connect the remaining pins to any GPIO pin.

## Example Usage

1. Clone the repository and configure the port numbers inside the `config_{arch}.h` file.
2. Pass the interface implementation into the initialization function:

```c
#include "main.h"
#include "pdsp188x/port/avr/avr.h"

int main(void) {
  uint16_t counter = 0;

  PDSP188x_Init(&PDSP188x_AVR_Driver);
  PDSP188x_SetBrightness(PDSP188x_BRIGHTNESS_LEVEL_100);

  while (1) {
    PDSP188x_Clear();
    PDSP188x_SendStr("C=");
    PDSP188x_SendInt16(counter++);
    _delay_ms(500);
  }
}
```
