Library Description
The library contains all the necessary functions for full DC motor control.
Key functions:
void dcmotor11_control(uint8_t dir, uint8_t speed) - Motor Control.void dcmotor11_stop() - Motor Stop.uint8_t dcmotor11_getFault() - Get Fault.Examples description
The application is composed of three sections :
void applicationTask()
{
uint8_t dataReady_;
char receivedData_;
dataReady_ = UART_Rdy_Ptr( );
if (dataReady_ != 0)
{
receivedData_ = UART_Rd_Ptr( );
switch (receivedData_)
{
case '+' :
{
/* Speed increase */
motorSpeed += 4;
if(motorSpeed >= _DCMOTOR11_VSET_4820mV)
{
mikrobus_logWrite("---- MAX SPEED ----", _LOG_LINE);
motorSpeed = _DCMOTOR11_VSET_4820mV;
dcmotor11_control(motorDir, motorSpeed);
}
else
{
mikrobus_logWrite("---- Speed increase ----", _LOG_TEXT);
mikrobus_logWrite(" MOTOR SPEED: ", _LOG_TEXT);
IntToStr(motorSpeed, demoText);
mikrobus_logWrite(demoText, _LOG_LINE);
dcmotor11_control(motorDir, motorSpeed);
}
break;
}
case '-' :
{
/* Speed decrease */
motorSpeed -= 4;
if( motorSpeed < _DCMOTOR11_VSET_480mV )
{
mikrobus_logWrite("---- MIN SPEED ----", _LOG_LINE);

dcmotor11_control(motorDir, motorSpeed);
}

case 's' :

}
break;
}
case 'd' :
{
/* Direction - Forward / Backword */
if(motorDir == 2)
{
mikrobus_logWrite("---- Direction - [FORWARD] ----", _LOG_LINE);

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.
