## 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);
|
|
}
|
|
}
|
|
```
