Key functions:

  • bargraph2_write(uint8_t regValue) - Generic write function
  • void bargraph2_reset() - Bargraph reset
  • void bargraph2_set(uint8_t value) - Sets the bargaph LEDs

Examples Description

  • System Initialization - GPIO and SPI module initialization
  • Application Initialization - SPI driver initialization
  • Application Task - Turning all 10 LED ON sequentially on the bargraph
void applicationTask()
{

  for (i = 0; i < 11; i++)
  {
   bargraph2_set(i);
   Delay_ms(100);
  }

}

Additional notes and information

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.
