GPS 4 Click carries the L70 compact GPS module from Quectel.
We provide a library for the Gps4 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Gps4 Click driver.
Config Object Initialization function.
void gps4_cfg_setup ( gps4_cfg_t *cfg );
Initialization function.
GPS4_RETVAL gps4_init ( gps4_t ctx, gps4_cfg_t cfg );
Generic parser function.
gps4_error_t gps4_generic_parser ( char rsp, uint8_t command, uint8_t element, char parser_buf );
Generic read function.
int32_t gps4_generic_read ( gps4_t ctx, char data_buf, uint16_t max_len );
Wake-up module.
void gps4_module_wakeup ( gps4_t *ctx );
This example reads and processes data from GPS4 clicks.
The demo application is composed of two sections :
Initializes driver and wake-up module.
void application_init ( void )
{
log_cfg_t log_cfg;
gps4_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
gps4_cfg_setup( &cfg );
GPS4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
gps4_init( &gps4, &cfg );
gps4_module_wakeup( &gps4 );

Reads the received data and parses it.
void application_task ( void )
{
gps4_process( );
parser_application( current_parser_buf );
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
