Function apigpio::constants::PI_error_code_lookup
source · Expand description
Provides string descriptions of a 32-bit pigpio error code.
val
is the value from Error:Pi
, or similar. It can be
one of the PI_*
values representing error codes.
The returned strings are
- The
PI_*
abbreviation name. - The comment from pigpiod.h.
If the returned value is None
, the error code was not
recognised. Probably this means that you are using a newer
pigpiod than this library.
(The error codes are negative. So you should pass a negative number to this function. Do not negate the error code to make it positive.)
