## Nonblocking continious ds18b20 handler, one wire over uart with dma

library include autosearch for devices on one bus by collisions after initialization and checking crc

```c

#include "dallas_temperature.h"

#include "UartOneWire.h"

extern UART_HandleTypeDef huart;

UartOneWire_HandleTypeDef ow;

DallasTemperatureData dt;

uint8_t resolution = TEMP_12_BIT;

int main () {

	OW_Init(&ow, &huart);

	DT_SetOneWire(&dt, &ow);

	DT_init(&dt, resolution);

	

	while(1) {

		uint32_t millis = HAL_GetTick();

		DT_ContiniousProceed(&dt, millis);	

	}

}

```

for get temperature and id devices go to  "DallasTemperatureData" declaration
