Detailed Description

SPIExtend Click example.

Description

In this example, if the connection is established, we read Accel axis of the connected Accel 14 Click boards to the SPI Extend Click ( Remote Mode ) which is connected by a LAN cable to SPI Extend Click ( Local Mode ) placed in the mikroBUS 1. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 1 sec.

The demo application is composed of two sections :

Application Init

Initializes SPI, sets INT pin as input and AN, RST, CS nad PWM pins as outputs and begins to write log. Also, initialization driver enables - SPI, set default configuration of the Accel 14 Click connected to the SPI Extend Click ( Remote Mode ).

Application Task

If the click is connected properly then the status becomes active and the X-axis coordinate is printed first on the UART terminal, then Y and finally Z. After 1s the process is repeated. In case an error has occurred, printed "LINK is not established" on UART Terminal.

Additional Functions :

void spiextend_accel14_get_axis ( uint8_t axis_out_reg ) - SPI Extend reading axis function.
void spiextend_display_status ( uint8_t check_status ) - SPI Extend check display status function.

< Logger config object.

< 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 LOG_MAP_USB_UART macro definition for detailed explanation.
