/* Test the integer size overriding in nanopb options.
|
|
* This allows to use 8- and 16-bit integer variables, which are not supported
|
|
* directly by Google Protobuf.
|
|
*
|
|
* The int_size setting will override the number of bits, but keep the type
|
|
* otherwise. E.g. uint32 + IS_8 => uint8_t
