NAME

6       spi-pipe - full-duplex SPI communication tool.
7

SYNOPSIS

9       spi-pipe options...
10

DESCRIPTION

12       This  program  allows full-duplex communications, sending data from its
13       standard input to the SPI slave, and displaying on its standard  output
14       the data received from the SPI port.
15
16       -d, --device=DEVICE
17              use the given Linux spidev character device.
18
19       -s, --speed=<int>
20              set the target SPI speed for transfer.
21
22       -b, --blocksize=<int>
23              set the block size (in bytes) for transfer.
24
25       -n, --number=<int>
26              set  the  number of blocks to transmit (-1 for continuous trans‐
27              fert).
28
29       -h, --help
30              display the help screen and exit.
31
32       -v, --version
33              display the version number and exit.

EXAMPLES

37       Get help:
38              $ spi-pipe -h
39
40       Send and receive at the same time
41              $ command-1 | spi-pipe --device=/dev/spidev0.0  | command-2
42              Note that command-1, command-2 and spi-pipe  run  simultaneously
43              in three different processes.
44
45       Send data to the SPI link
46              $ command-1 | spi-pipe --device=/dev/spidev0.0
47
48       Receive data from the SPI link
49              $ spi-pipe --device=/dev/spidev0.0 < /dev/zero | command-2
50              You  can  also  use command-2 < /dev/spidev0.0 but with spi-pipe
51              you can control what is sent to the device (always `0` here).
52
53       Read 40 blocks of 4 bytes from the SPI link
54              $  spi-pipe --device=/dev/spidev0.0 -b 4 -n  40  <  /dev/zero  |
55              command-2
