NCC# Description
188 Cannot modify a constant object [NCC#188]
The Neuron C compiler enforces the const keyword strictly. In addition,
data or objects declared using const might be placed in read-only memory
areas by the compiler. However, const network input variables are not
placed in read-only memory, because their values are updated by network
variable messages from other devices. Furthermore, note that constant
configuration parameters are placed in read-only memory unless the
directive #pragma codegen put_read_only_cps_in_data_memory is used.
189 Cannot modify via pointer-to-constant-object [NCC#189]
To prevent data that is declared const from being modified, Neuron C will
not permit constant objects to appear on the left-hand side of an
assignment statement, nor will it permit modification of the constant object
by a pointer with the const attribute, or by the ++ or - - operators.
Note that, in the case of network variables, a network variable declared as
const (or config, which implies const) cannot be modified in the device
where it is so declared, but it can be modified by other nodes in the
network.
190 Object is not a suitable assignment target [NCC#190]
The left-hand side of assignment operators, and the target of increment or
decrement operators must be nonconstant variables, or fields of
nonconstant structures or unions, or elements of arrays.
191 Object of call is not a function [NCC#191]
The syntax encountered is function call syntax, for example:
expression ( [ expression-list ] )
however, the expression being called is not a function (or a pointer to a
function). Note that this error could occur by omitting an operator.
If the following were intended:
int a, b, c, d;
a = b * (c + d);
but the following were actually written (omitting the multiplication
operator):
int a, b, c, d;
a = b (c + d);
This would appear to be a function call, but b is not a function.
192 Call to function without prototype [NCC#192]
Neuron C is more restrictive than ANSI C in this area. The Neuron Chip's
hardware architecture does not permit calling undeclared functions with
unknown numbers of parameters.
