Library Description
Library contains functions for setting states of RST and PWM pins Library contains function for setting configuratoin word Library contains function for setting output value Library contains function for calculating output value expressed in percent Library contains function for device initialization.
Key functions:
uint8_t stepup_setConfig( uint16_t config )
- sets first 4 bits in command word.uint8_t stepup_setOut( uint16_t out_value )
- sets output value.void stepup_init(void)
- initializes the device.Examples description
The application is composed of three sections :
void applicationTask( )
{
if (UART_Data_Ready( ) == 1)
{
uart_char = UART_Read( );
switch ( uart_char )
{
case '-' :
{
if (out_value < 4095)
{
out_value++;
}
stepup_setOut( out_value );
stepup_logPercent( out_value );
break;
}
case '+' :
{
if (out_value > 0)
{
out_value--;
}
stepup_setOut( out_value );
stepup_logPercent( out_value );
break;
}
default :
{
mikrobus_logWrite( "error : invalid command", _LOG_LINE );
break;
}
}
}
}

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.
