Library Description
Initializes and defines the GPIO click driver and functions witch turn on or turn off the LED.
Key functions:
Example description
The application is composed of three sections:
void applicationTask()
{
uint8_t check_flag;
if(!Ow_Reset(OW_PORT, OW_PIN))
{
check_flag = Read_Key();
if(check_flag = 0)
{
mikrobus_logWrite("Key exist", _LOG_LINE);
Delay_ms(500);
}else
{
mikrobus_logWrite("Key doesn't exist", _LOG_LINE);
Delay_ms(500);
}
}
else
{
mikrobus_logWrite("Add new key", _LOG_LINE);
Delay_ms(500);
while(Ow_Reset(OW_PORT, OW_PIN))
{
if(check_state == 0)
{
mikrobus_logWrite("Insert iButton", _LOG_LINE);
Delay_ms(500);
check_state = 1;
}
}
check_flag = Add_key();
if(check_flag == 0)
{
mikrobus_logWrite("Key added", _LOG_LINE);
Delay_ms(500);
}else
{
mikrobus_logWrite("Key already exist", _LOG_LINE);
Delay_ms(500);
}
mikrobus_logWrite("Read iButton", _LOG_LINE);
check_state = 0;
}
Delay_ms(100);
}
Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or 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, or any other terminal application of your choice, can be used to read the message.
