Library Description

Initializes and defines gpio driver and constant values witch can be used in example code, and also performs the chip enable.

Key functions:

• void stspin250_enable(uint8_t state) - Function for enable or disable device.
• void stspin250_setPH(uint8_t state) - Function for select the direction of rotation of the motor.

Examples description

The application is composed of the three sections :

• System Initialization - Sets AN,RST,CS and PWM pin as OUTPUT and INT pin as INPUT.
• Application Initialization - Initialization driver init, PWM init and enable device.
• Application Task - (code snippet) - Changes the PWM dutyCycle and controls the motor speed. You can change the direction of the motor rotation by setting PH to 0 or 1..

void applicationTask()
{
// PWM DEMO EXAMPLE
    _dutyCycle += 250;
    stspin250_pwmSetDuty(_dutyCycle);
    if (_dutyCycle > 40000 )
    {
        _dutyCycle = 0;
        stspin250_pwmStop();
        Delay_ms(2000);
        stspin250_pwmStart();
    }
	stspin250_setPH(1);
    Delay_ms( 200 );
}

Other mikroE Libraries used in the example:

• GPIO
• PWM

Additional notes and informations

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.
