mikroSDK Library Blog
Library description
This library contains functions that control the Enable pin and can retrieve the state of the PG pin.
Key functions:
void boost2_setENpin(uint8_t newState)- Sets the EN pin
uint8_t boost2_getPGpin()- Gets the status of the PG pin
Example description
The application is composed of three sections :
- System Initialization - Initializes PIN directions and UART logger
- Application Initialization - Initializes click driver
- Application Task (code snippet) - Demonstrates the use of the click drivers function. It shows how to enable or disable click operation, and how to check if supplied voltage is good.
void applicationTask()
{
mikrobus_logWrite("Enabling click operation...", _LOG_LINE);
boost2_setENpin(1);
Delay_ms(3000);
mikrobus_logWrite("Checking output voltage...", _LOG_LINE);
Delay_ms(500);
if(boost2_getPGpin())
{
mikrobus_logWrite("Output voltage good.", _LOG_LINE);
}
else
{
mikrobus_logWrite("Output voltage incorrect.", _LOG_LINE);
}
Delay_ms(3000);
mikrobus_logWrite("Disabling click operation...", _LOG_LINE);
boost2_setENpin(0);
Delay_ms(5000);
}

Additional notes and information
Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
