SPI on OrangePi One Success

[mantouboji]

After some hack,  I use the SPI port on OPi One to connect with a MAX6675 board. 

 

The SPI port on One is SPI0,  so armbianEnv.txt should include these:

 

overlays=spi-spidev
param_spidev_spi_bus=0
param_spidev_spi_cs=0

 

the MAX6675 connects to OPi One as:

 

MAX6675                       One GPIO

------------------------------------------

VCC                                 PIN17

GND                                PIN20

SCK                                 PIN23

CS                                   PIN24

SO                                  PIN21

 

 

Then use the attachment program to read from MAX6675
