Name

spi_w8r16be — SPI synchronous 8 bit write followed by 16 bit big-endian read

Synopsis

ssize_t spi_w8r16be (struct spi_device * spi,
 u8 cmd);
 

Arguments

spi

device with which data will be exchanged

cmd

command to be written before data is read back

Context

can sleep

Description

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.

Callable only from contexts that can sleep.

Return

the (unsigned) sixteen bit number returned by the device in cpu endianness, or else a negative error code.
