5-42 Neuron C Compiler Errors (NCC)

NCC# Description

332 Problem reading 'snvt.typ' [NCC#332]

The snvt.typ file is read by the compiler to obtain definitions of the

current Standard Network Variable Types (whose names begin with

the characters SNVT_). This type file is located in the TYPES

subdirectory of the LonBuilder system directory. The LonBuilder

system directory is, by default, named \lb. This error message does

not indicate a missing file, rather, it indicates a read error on the file,

possibly due to a disk or hardware failure, or a corruption in the DOS

file system. The DOS command chkdsk can be used to diagnose file

system errors. This error is not applicable in version 4.00 or later

versions of the Neuron C Compiler.

334

Specify 'idempotent_duplicate_<off,on>' pragma with

'micro_interface' [NCC#334]

The Microprocessor Interface Program option for a Neuron C

compilation requires specification of one of the following two

pragmas:

#pragma idempotent_duplicate_off

#pragma idempotent_duplicate_on

For more information, see Chapter 1 of the Neuron C Programmer's

Guide.

335

Byte/Nibble output has no effect on timer/counter output pins

[NCC#335]

A timer/counter output device has precedence over a byte or nibble

output device. The pin used by the timer/counter device, either IO_0

or IO_1, will not be affected by any output operations on the byte or

nibble device. However, the remaining pins of the byte or nibble

device will still function. The declaration is permitted for situations

such as a timer/counter device on pin IO_0, and a 7-bit output device

on pins IO_1 through IO_8, which could use a byte device declared

on pin IO_0 to accomplish the function.

336 Struct assign for EEPROM dest limited to 255 bytes [NCC#336]

The Neuron Chip firmware functions that copy blocks of memory to

EEPROM destination addresses support a maximum length of 255

bytes per copy. Larger blocks can be copied by using multiple calls,

substructure assignments, etc.

337 Priority bind_info options ignored for NV ‘<name>’ [NCC#337]

Any explicit priority bind_info( ) options for network variables are

ignored when the number of priority buffers is zero. The number of

priority buffers is set to zero explicitly by the priority buffer count

pragmas (see the Compiler Directives chapter of the Neuron C

Reference Guide and the Memory Management chapter of the Neuron

C Programmer's Guide for more information).
