# UART1Wire Click | ||
|
||
- **CIC Prefix** : UART1WIRE | ||
- **Author** : Katarina Perendic | ||
- **Verison** : 1.0.0 | ||
- **Date** : jun 2018. | ||

### Software Support | ||
|
||
We provide a library for the UART1Wire Click on our [LibStock](https://libstock.mikroe.com/projects/view/2439/uart-1-wire-click) | ||
page, as well as a demo application (example), developed using MikroElektronika | ||
[compilers](http://shop.mikroe.com/compilers). The demo can run on all the main | ||
MikroElektronika [development boards](http://shop.mikroe.com/development-boards). | ||
|
||
**Library Description** | ||
|
||
The library initializes and defines the UART bus driver and drivers that offer a choice for writing data on UART. | ||
The library includes function for read n data and functions for go to Command/Data mode. | ||
The user also has the function for reset chip and storage read data. | ||
|
||
|
||
Key functions : | ||
|
||
- ``` void uart1wire_writeCommand(uint8_t input) ``` - Functions for write one byte on UART | ||
- ``` uint8_t uart1wire_readByte() ``` - Functions for read byte from UART | ||
- ``` void uart1wire_goToCommandMode() ``` - Functions for go to command mode | ||
- ``` void uart1wire_goToDataMode() ``` - Functions for go to data mode | ||
- ``` void uart1wire_readData(uint8_t *buf, uint8_t nData) ``` - Functions for read data | ||
|
||
**Examples Description** | ||
|
||
The application is composed of three sections : | ||
|
||
- System Initialization - Initializes UART module | ||
- Application Initialization - Initializes Driver init, interrupt routine and init thermo 2 click | ||
- Application Task - (code snippet) - Reads the temperature from the Thermo 2 click board and logs data to UART. | ||
Connection between Thermo 2 and UART 1 Wire is made through 1- Wire interface. | ||
You can place thermo 2 click on mikrobus 2 socket and use side headers to make connection between click boards. | ||
|
||
|
||
```.c | ||
void applicationTask() | ||
{ | ||
/* Start converzion */ | ||
uart1wire_reset(); | ||
uart1wire_goToDataMode(); | ||
Delay_10ms(); | ||
uart1wire_writeCommand(_UART1WIRE_SKIP_ROM); | ||
uart1wire_writeCommand( 0x44 ); | ||
Delay_ms( 750 ); | ||
|
||
/* Start reading temperature */ | ||
uart1wire_reset(); | ||
uart1wire_goToDataMode(); | ||
Delay_10ms(); | ||
uart1wire_writeCommand(_UART1WIRE_SKIP_ROM); | ||
uart1wire_writeCommand( 0xBE ); | ||
Delay_10ms(); | ||
|
||
uart1wire_readData(&dataBuffer[0], 8); | ||
|
||
Temp = dataBuffer[ 1 ]; | ||
Temp = Temp << 8; | ||
Temp = Temp | dataBuffer[ 0 ]; | ||
|
||
fTemp = Temp * 0.0625; | ||
mikrobus_logWrite(" Temperature : ", _LOG_TEXT); | ||
FloatToStr(fTemp, demoText); | ||
mikrobus_logWrite(demoText, _LOG_LINE); | ||
|
||
Delay_ms( 1000 ); | ||
} | ||
``` | ||
|
||
The full application code, and ready to use projects can be found on our | ||
[LibStock](https://libstock.mikroe.com/projects/view/2439/uart-1-wire-click) page. | ||

||
**Additional notes and informations** | ||
|
||
Depending on the development board you are using, you may need | ||
[USB UART click](http://shop.mikroe.com/usb-uart-click), | ||
[USB UART 2 Click](http://shop.mikroe.com/usb-uart-2-click) or | ||
[RS232 Click](http://shop.mikroe.com/rs232-click) to connect to your PC, for | ||
development systems with no UART to USB interface available on the board. The | ||
terminal available in all Mikroelektronika | ||
[compilers](http://shop.mikroe.com/compilers), or any other terminal application | ||
of your choice, can be used to read the message. | ||
