SPI_W8R16BE(9) | Serial Peripheral Interface (S | SPI_W8R16BE(9) |
NAME¶
spi_w8r16be - SPI synchronous 8 bit write followed by 16 bit big-endian readSYNOPSIS¶
ssize_t
spi_w8r16be(struct spi_device * spi,
u8 cmd);
ARGUMENTS¶
spidevice with which data will be exchanged
cmd
command to be written before data is read back
CONTEXT¶
can sleepDESCRIPTION¶
This returns the (unsigned) sixteen bit number returned by the device in cpu endianness, or else a negative error code. Callable only from contexts that can sleep. This function is similar to spi_w8r16, with the exception that it will convert the read 16 bit data word from big-endian to native endianness.COPYRIGHT¶
