Library Description

This library holds functions that allow user to start up the device, write to the device, make one clock pulse and control each individual pin used.

Key functions:

• void scanner_startup (); - Function is used to start up the linear array sensor.
• void scanner_serial_cmd ( uint8_t cmd ); - Function is used to write command to the device.
• void scanner_clock ( ); - Function is used to make SCK pulse.
• void scanner_read_pixel ( uint8_t *pixel_data ); - Function is used to read pixel status.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO and LOG structures, sets MOSI and SCK pins as output and MISO pin as input.
• Application Initialization - Initialization driver enables GPIO and starts device and sets gain and offset.
• Application Task - Device reads device pixels and logs values in 3 rows, left, center and right.

void application_task ( )
{
    scanner_pixel_log( log_write );
}

Other mikroE Libraries used in the example:

• Conversions
• UART

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.
