Library Description

Library contains functions for setting CS and RST pins to HIGH or LOW level.

Key functions:

• void dcmotor9_csSet( uint8_t pinState ) - Sets CS pin state to HIGH or LOW.
• void dcmotor9_rstSet( uint8_t pinState ) - Sets CS pin state to HIGH or LOW.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes LOG, PWM pin as output, RST pin as input and CS pin as output.
• Application Initialization - Initializes GPIO driver and ADC and PWM functionalities.
• Application Task - Executes dcmotor9_getVoltAmperWatt( ) - function.

void applicationTask( )
{
    _adcValue = dcmotor9_adcRead( );
    WordToStr( _adcValue, text );
    mikrobus_logWrite( text, _LOG_TEXT );
    mikrobus_logWrite( " ", _LOG_LINE );
    Delay_ms(750);
}

Additional Functions :

• dcmotor9_init( ) - Initializes PWM and ADC.
• dcmotor9_getVoltAmper( float adcRef ) - Performs ADC measurements and converts them to values of current and voltage.

Notes:

• Change pwm frequencty (uint16_t _frequency) from 0 to some value.
• Change pwm duty cycle (_dutyCycle = _maxDuty) from _maxDuty to value in range from 0 - _maxDuty.
• Optional : call - dcmotor9_getVoltAmper( adcRef ) - function to get value of voltage and current on shunt.
• float adcRef - is ADC value read from AN pin while no load is connected to device.

Other mikroE Libraries used in the example:

• ADC
• PWM
• UART
• Conversions

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.
