| Wizzard Error? Undefined Identifiers WDT_ON & WDT_DIV_16 |

Please pardon a very rusty PIC CCS programmer. I am trying to write new code for an old product using PIC16C58A chips. My 20 year old code doesn't compile under (PCWH) PCB 5.058 so I am trying to start with "Hello World" and add one part at a time. I used the Wizard to make is simple dummy program to start with:
Dummy_main.c
| Code: |
#include <Dummy_main.h>
void main()
{
setup_wdt(WDT_ON);
setup_wdt(WDT_2304MS|WDT_DIV_16); //~2.3 s reset
while(TRUE)
{
//TODO: User Code
}
} |
Dummy_main.h
| Code: |
#include <16C58A.h>
#FUSES WDT //Watch Dog Timer
#use delay(crystal=7.3728MHz,restart_wdt)
|
When I try to compile this simple bit I get:
| Code: |
*** Error 12 "Dummy_main.c" Line 5(11,17): Undefined identifier WDT_ON
*** Error 12 "Dummy_main.c" Line 6(22,32): Undefined identifier WDT_DIV_16
2 Errors, 0 Warnings.
Build Failed.
|
"WDT_ON" and "WDT_DIV_16" do not appear in 16C58A.h.
Is the Wizard putting in things it should not, or should these WDT bits be defined elsewhere?

The 'Wizard' is as smart as PROTEUS......
simply do NOT use it...
I started with PCM V2.534 and have never used either. Frankly I don't trust them. been proven over and over they ain't smart
Consider who wrote the Wizard. That guy does NOT code the way you or I do, so 'stuff' is either defaulted on or off, the opposite of how we program so you'll spend hours in a daze wondering WHY it doesn't work...it used to...
Start from scratch, enter in EVERY fuse the way YOU want, cut a 'flashing LED' program. When it finally works save it twice. The second copy is your starting point for the next program. This way you'll ALWAYS have KNOWN programs to go back to. If you keep editing the same program over and over...it'll fail and you'll be in a daze again.....

The problem here is that the 16C58A, does not have a software
configurable WDT. On early PIC's the watchdog can only be enabled
in the fuses. No software option.
On the timings, this chip only has the 'expected times', not divisors
directly available. So WDT_288MS.
I think these chips really 'predate' the Wizard, so it does not properly
handle them.
At the very least, you should be using the 58B, not the A. This is a
slightly later replacement chip. However even better there are 'F' chips
that are pin compatible and would help the overall performance.
The 16F716 for example, is pin compatible, more RAM, more ROM etc.. |
