Library Description

Library performs the control of the output pins (OUT1 - OUT7) by setting input pins (IN1 - IN7).
For more details check the documentation.

Key functions :

• void driver_setIN1( uint8_t state ) - Function determines state of output 1 (OUT1).

Example description

The application is composed of three sections :

• System Initialization - Initializes peripherals and pins.
• Application Initialization - Initializes GPIO driver and selects which inputs will be set in operation. Bits from 0 to 6 (selectIN) select inputs from IN1 to IN7, respectively.
• Application Task - (code snippet) - Performs cycles in which selected inputs will be turned on for pulse width delay time one by one. When one input is turned on, he will be turned off after the desired delay time before the next input be turned on.

void applicationTask()
{
 temp = 1;

 for (count = 0; count < 7; count++)
 {
 switch (selectIN & temp)
 {
 case 0x01 :
 {
 driver_setIN1( enableIN );
 Delay_ms( pulseWidth );
 driver_setIN1( disableIN );
 break;
 }
 case 0x02 :
 {
 driver_setIN2( enableIN );
 Delay_ms( pulseWidth );
 driver_setIN2( disableIN );
 break;
 }
 case 0x04 :
 {
 driver_setIN3( enableIN );
 Delay_ms( pulseWidth );
 driver_setIN3( disableIN );
 break;
 }
 case 0x08 :
 {
 driver_setIN4( enableIN );
 Delay_ms( pulseWidth );
 driver_setIN4( disableIN );
 break;
 }
 case 0x10 :
 {
 driver_setIN5( enableIN );
 Delay_ms( pulseWidth );
 driver_setIN5( disableIN );
 break;
 }
 case 0x20 :
 {
 driver_setIN6( enableIN );
 Delay_ms( pulseWidth );
 driver_setIN6( disableIN );
 break;
 }
 case 0x40 :
 {
 driver_setIN7( enableIN );
 Delay_ms( pulseWidth );
 driver_setIN7( disableIN );
 break;
 }
 default :
 {
 break;
 }
 }

 temp <<= 1;
 }
}

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.
