Library Description

The library carries functions related to GPIO pins control of the Buck 8 click. PWM control is not part of the library and should be initialized depending on the development system.

Key functions:

• void buck8_setMode(uint8_t mode) - Set working mode.
• void buck8_enable( uint8_t state ) - Returns the status of the Click board™.

Examples Description

The demo application is composed of three sections:

• System Initialization - Initialization of the CS and RST pin as INPUT.
• Application Initialization - Initialization Driver init and set PWM frequency on 450kHz (OPEN mode).
• Application Task - (code snippet) - Logs the message to USBUART if the voltage is greater than the maximum setpoint value.

void applicationTask()
{
 if( buck8_getState() && flag == 0)
 {
 mikrobus_logWrite("max range ",_LOG_LINE);
 flag = 1;
 }
 else 
 {
 flag = 0;
 }
 Delay_1sec();
}

Other MikroElektronika libraries used in the example:

• UART

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.
