GNSS ZOE Click is a evaluation board for ultra small ZOE-M8Q GNSS SiP receiver from u-blox.
We provide a library for the GNSS ZOE 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for GNSS ZOE Click driver.
gnsszoe_cfg_setup
Config Object Initialization function.
void gnsszoe_cfg_setup ( gnsszoe_cfg_t *cfg );
gnsszoe_init
Initialization function.
err_t gnsszoe_init ( gnsszoe_t *ctx, gnsszoe_cfg_t *cfg );
gnsszoe_default_cfg
Click Default Configuration function.
err_t gnsszoe_default_cfg ( gnsszoe_t *ctx );
gnsszoe_reset_device
This function resets the device by toggling the RST pin.
void gnsszoe_reset_device ( gnsszoe_t *ctx );
gnsszoe_generic_read
This function reads a desired number of data bytes from the module.
err_t gnsszoe_generic_read ( gnsszoe_t *ctx, uint8_t *data_out, uint8_t len );
gnsszoe_parse_gngga
This function parses the GNGGA data from the read response buffer.
err_t gnsszoe_parse_gngga ( char *rsp_buf, uint8_t gngga_element, char *element_data );
This example demonstrates the use of GNSS ZOE Click by reading and displaying the GNSS coordinates.
The demo application is composed of two sections :
Initializes the driver and resets the Click board.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
gnsszoe_cfg_t gnsszoe_cfg; /**< Click config object. */
/**
* 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.
gnsszoe_cfg_setup( &gnsszoe_cfg );
GNSSZOE_MAP_MIKROBUS( gnsszoe_cfg, MIKROBUS_1 );
err_t init_flag = gnsszoe_init( &gnsszoe, &gnsszoe_cfg );
if ( ( UART_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
Reads the received data, parses the GNGGA info from it, and once it receives the position fix it will start displaying the coordinates on the USB UART.
void application_task ( void )
{
gnsszoe_process( &gnsszoe );
if ( app_buf_len > ( sizeof ( GNSSZOE_RSP_GNGGA ) + GNSSZOE_GNGGA_ELEMENT_SIZE ) )
{
gnsszoe_parser_application( app_buf );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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. UART terminal is available in all MikroElektronika compilers.
