Expected result
|
|
===============
|
|
The test code transmits one byte with each SPI mode and a string over the
|
|
software SPI MOSI line. This can be verified with a Logic Analyzer connected to
|
|
the corresponding pins. When you see 0xa5 in all four SPI modes and the string
|
|
"Soft SPI Test String" in SPI mode 0 being transmitted via the CLK and MOSI pin,
|
|
the test is successful.
|
|
|
|
Notes
|
|
==========
|
|
- Because the module does not cover MISO inputs, neither does the test.
|
|
- The definition of SOFT SPI devices is done via the CFLAGS in the Makefile
