Hello,
I am trying to test a digipot MCP41010 on a BeagleBone Black and I can't
make it work.
I made the connections between BeagleBone and the digipot MCP41010 as below:
PORT | CS0 |
DO |DI |SCLK
SPI0 |
P9_17 |
P9_21 |
P9_18 |
P9_22
I used the code below , from this page:
https://adafruit-beaglebone-io-python.readthedocs.io/en/latest/SPI.html, to
test the output of the BeagleBone:
*import Adafruit_BBIO.SPI as SPI
from Adafruit_BBIO.SPI import SPI
# spi = SPI(bus, device) #/dev/spidev<bus>.<device>
# /dev/spidev0.0
spi = SPI(0, 0)
print(spi.xfer2([32, 11, 110, 22, 220]))
spi.close()*
The output should be: *32, 11, 110, 22, 220*; but, it is: *255, 255, 255, 255,
255*.
Can anybody help me, please?
Thanks for the attention
