Library Description

The library initializes and defines SPI drivers along with the driver that gives an option to set desired positive and negative output voltages.

Key functions:

  • void boostinv2_enable() - Functions for enable chip.
  • void boostinv2_setPositiveVoltage( uint16_t voltage ) - Functions for set positive output voltage.
  • void boostinv2_setNegativeVoltage( uint16_t voltage ) - Functions for set negative output voltage.

Example description

The application is composed of three sections:

  • System Initialization - Initializes I2C module and sets RST,AN,CS and PWM pin as OUTPUT
  • Application Initialization - Initializes Driver init and enable chip
  • Application Task - (code snippet) - Changes the positive and negative output voltage. Positive output voltage goes from 5V to 15V with Negative output voltage goes from -5V to -15V
void applicationTask()
{
 /* Positive output voltage */
 boostinv2_setPositiveVoltage( _BOOSTINV2_POS_VOUT_6V );
 Delay_ms( 3000 );
 boostinv2_setPositiveVoltage( _BOOSTINV2_POS_VOUT_8V );
 Delay_ms( 3000 );
 boostinv2_setPositiveVoltage( _BOOSTINV2_POS_VOUT_12V );
 Delay_ms( 3000 );
 boostinv2_setPositiveVoltage( _BOOSTINV2_POS_VOUT_14V );
 Delay_ms( 3000 );
 boostinv2_setPositiveVoltage( _BOOSTINV2_POS_VOUT_12V );
 Delay_ms( 3000 );
 boostinv2_setPositiveVoltage( _BOOSTINV2_POS_VOUT_8V );
 /* Negative output voltage */
 boostinv2_setNegativeVoltage( _BOOSTINV2_NEG_VOUT_5V );
 Delay_ms( 3000 );
 boostinv2_setNegativeVoltage( _BOOSTINV2_NEG_VOUT_7V );
 Delay_ms( 3000 );
 boostinv2_setNegativeVoltage( _BOOSTINV2_NEG_VOUT_13V );
 Delay_ms( 3000 );
 boostinv2_setNegativeVoltage( _BOOSTINV2_NEG_VOUT_7V );
}

Additional notes and information

Depending on the development board you are using, you may need USB UART clickUSB 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.
