bit manipulation - Error codes OR'd together -


i having trouble figuring 1 out , use help. data sheet hardware says "the reported error code or’d result of each detected error. error codes given in table 3."

table 3 

0x00 -> no error 0x01 -> power error 0x02 -> receiver error 0x03 -> transmitter error

the data sheet shows example.

example : (etv001t0c) + checksum -> test status 0x0c (rx , tx error)

0c error byte. first question - math wrong? have no idea getting 0c from. pretty sure 0x02 | 0x03 = 0x03. , second if 0c how figure out errors in that?

the table giving giving bit shift positions, used << operator.

1 << 0x00 = 0001b (?) -> no error 1 << 0x01 = 0010b -> power error 1 << 0x02 = 0100b -> receiver error 1 << 0x03 = 1000b -> transmitter error

using python calculator:

>>> (1 << 2) | (1 << 3) 12 >>> hex((1 << 2) | (1 << 3)) '0xc'

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
