Why 3 write statements in SPI example?
I understand the SPI master example code is writing a series of 1, 2, 3..., but what is the purpose of the device.write statements above and below the counting output?

It is just a random program. No idea why the 0xE0, maybe it was intended as 0xF0 (four ones, four zeros). 0x55 (and 0xAA) are popular ones since they create a '10101010' pattern.
