We provide a library for the BarGraph3 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library initializes and defines SPI bus driver and drivers that offer a choice for writting data in registers and reading data from registers.
Library includes functions for logging values on the BarGraph display.
User can enable and disable the chip with the function bargraph3_enable(), which is supported in the library.
Key functions :
void bargraph3_display(uint8_t ctrl, uint8_t dir, uint8_t counter)- Displays functionvoid bargraph3_enable(uint8_t state)- Functions for enable the chip
Examples Description
The application is composed of three sections :
- System Initialization - Initializes SPI module and sets AN, RST, CS and PWM pin as OUTPUT
- Application Initialization - Initialization driver init, enable device and set PWM
- Application Task - (code snippet) - Counter passes through the loop and logs the value of the counter on the bargraph display
void applicationTask()
{
uint8_t bargraph_cnt;
for (bargraph_cnt = 0; bargraph_cnt <= 5; bargraph_cnt++)
{
bargraph3_display(_BARGRAPH3_INCREASE_LED, _BARGRAPH3_DIRECTION_BOTTOM_TO_TOP, bargraph_cnt);
Delay_1sec();
}
}The full application code, and ready to use projects can be found on our LibStock page.

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.
