The DlnSpiMasterRead() function receives data via SPI bus. The received data is an array of 1-byte elements.
DlnSpiMasterRead()
DLN_RESULT DlnSpiMasterRead( HDLN handle, uint8_t port, uint16_t size, uint8_t *readBuffer );
A handle to the DLN-series adapter.
A number of the SPI master port.
The size of the message buffer. This parameter is specified in bytes. The maximum value is 256 bytes.
A pointer to an array of unsigned 8-bit integers that receives data from slave during the function execution.
The function successfully received data.
The port number is not valid. Use the DlnSpiMasterGetPortCount() [1] function to find the maximum possible port number.
The SPI master port is disabled. Use the DlnSpiMasterEnable() [2] function to activate the SPI master port.
The DlnSpiMasterRead() function is defined in the dln_spi_master.h file.
