Detailed Description

GNSS 21 Click Example.

Description

This example demonstrates the use of GNSS 21 Click by reading and displaying the GNSS coordinates.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.

Application Task

Reads the received data, parses the NMEA GGA info from it, and once it receives the position fix it will start displaying the coordinates on the USB UART.

Additional Function

  • static void gnss21_log_app_buf ( void )
  • static err_t gnss21_process ( gnss21_t *ctx )
  • static void gnss21_parser_application ( uint8_t *rsp )

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 LOG_MAP_USB_UART macro definition for detailed explanation.
