18F46K80-NEW COMPILER Ver 4.121- [SOLVED] FIXED
PostPosted: Tue Mar 29, 2011 1:50 pm     Reply with quote

Hi,
There are new changes with this chip?? TGM MAY 7, 2011 see post at end


This compiler change for the K80 chip setup in Ver 4.121 is good now!!!

#include <18F46K80.h>
#device ADC=16
#device HIGH_INTS=true
#fuses NOWDT,NOPROTECT,NOBROWNOUT,PUT,NOMCLR,HSH,PLLEN // 4x PLL enable
#use delay(clock=64M, crystal=16M) // 4x PLL enable
#define VSS 0xFF //Analog Negative Channel connected to Vss

//This (NOMCLR) and programming of EEPROM is FIXED in the NEW CCSLOAD Progammer software
GO TO CCS site and load the new software for ICD-U64.....

At this time the ICD-U40 may not work with the new ccsload software so be aware that problem and U40 device.

//can program fuse "NOMCLR" so Pin 1 is now RE3 "INPUT ONLY", no master reset

---------------
Thanks Nick, --------- for your great work on this fix -----------
---------------

Thank You,
Tom W2DRZ Question

FWIW, I am using the 18F45Kxx and 18F46Kxx chips with no problems on PCWH 4.114.

FIXED IN NEW COMPILER.

18F46K80 ---NEW COMPILER Ver 4.121--- [SOLVED]
PostPosted: Sun May 01, 2011 9:25 pm     Reply with quote

Hi,

After have a problem with the interrupts not working that had mux settings with interrupts and with ANALOG use on the same pin,
4 days of working on fix.......

I found a 'DUMB' programming setting on my part...........

This will not do a error or warning so just be aware not to do the same.

This is GOOD:
setup_adc_ports (sAN0|sAN1|sAN3|VSS_VDD); // ect of ad pins

THIS IS BAD--------------------

setup_adc_ports (sAN0-sAN1-sAN3,VSS_VDD);

This will enable a override of 'MUXED' pins to BE --ANALOG and
NO interrups on these 'MUXED' pins will work correctly-----
Now all seems to work just fine with the 18F46K80 chip including "FUSE NOMCLR"

Obviously. Where did you get the idea to combine sANx constants with a minus operator?

18F46K80 MUX PROBLEMS with RC0 & RC1 pins
PostPosted: Sat May 07, 2011 2:51 pm     Reply with quote

Hi Here is the latest.

Have issues with RC0 and RC1 not switched to being I/O ports,
Need a fix any help?
This is in the spec sheets but do not find a command in the compiler to deal with the 'SOSCSEL bits' must be set to Digital mode.

SEE pg 58:
3.3 Clock Sources and
Oscillator Switching
If a secondary oscillator is not desired and digital I/O on
port pins, RC0 and RC1, is needed, the SOSCSEL bits
must be set to Digital mode.

Also have ISSUES with the setting of:
#define VSS 0xFF //Analog Negative Channel connected to Vss

The Analog change to using the
PIC18FXX80 to PIC18FXXK80 Migration Guide
12-BIT ANALOG-TO-DIGITAL
CONVERTER (A/D)

while PIC18FXXK80 devices have a 12-bits with a sign
bit A/D Converter.
The converter in PIC18FXXK80 devices is a differential
A/D Converter (with two inputs), while PIC18FXX80
devices have a single input. The PIC18FXXK80
devices differential A/D Converter can be configured as
a single input A/D Converter by connecting the negative
input internally to AVSS


This command has a differance voltage from ANALOG VDVSS ground and core VSS ground of 2 millivolts to 4 millivolts.

Any comments on a fix to the analog problem and the compiler command for RC0 & RC1 I/O setting.



Thank You,

Post an extremely short test program that demonstrates these problems
and that I can "copy and paste" into MPLAB, and compile, to see these
problems. The program needs to have the #include for the PIC, #fuses,
#use delay, main(), and be extremely short. I assume you are using
vs. 4.121 for these tests. If not, let me know.

The 18F46K80.h file lists this fuse in it, and it works:
Code:

SOSC_DIG


Regarding the analog problem, can you explain more about it ?
Make a small (only 1/5 of the code that you posted) that
shows what you are trying to do with the A/D converter.
Explain in what way it doesn't work. Explain how you know it
doesn't work.

Hi,
These old eyes did not see the fuse after 3 days of looking at the problem never found that fuse, BIG AS ALL GET OUT, in the first line....

Code:

// 05/08/2011 - SIMPLE TEST PROGRAM FOR NEW THINGS IN THIS -K80- CHIP
// compiler ver. 4.121     ICD-U64 with ccsload 28 software installed

#include <18F46K80.h>

#fuses NOWDT,NOPROTECT,NOBROWNOUT,PUT,MCLR,HSH,PLLEN,SOSC_DIG // 4x PLL enable
#use delay(clock=64M, crystal=16M)  // 4x PLL enable

#USE STANDARD_IO(C)
#define VSS 0xFF                      //Analog Negative Channel connected to Vss
short    new_val;
long     val;
float    gAzimuth;

void main ()
{
   setup_adc_ports (sAN0|sAN1|sAN3|VSS_VDD);       // for 18F46K80 04/12/2011
   setup_adc(ADC_CLOCK_DIV_64|ADC_TAD_MUL_20);     // 64 MHz & 16 bit conversion
   set_adc_channel(0);
   new_val = true;
   enable_interrupts (int_ad);
   enable_interrupts (global);               // start all interrupts

   RunME ();
}

void RunME ()
{
   do{
      if (new_val){   
        read_adc (ADC_START_ONLY); // Channel 0 Atod
        new_val = false;
     }
   }
   while (true);
}

#int_ad        // ADC interrupt service routine
void adc_isr ()
{
   val = gAzimuth = read_adc (ADC_READ_ONLY);    // read the ADC result
   new_val = true;
}


The voltage for wiper ground output of the port will be negative value reading.
Not zero value as normal single ended analog core.

It is not any fix I find,
but then again I can not spell 'SOSC_DIG' or see it either??

That fuse FIXED the 'C0 and C1' I/O problem fine--------------

I can not find this setting in the .H file, do not know where I found this setting now??

#define VSS 0xFF //Analog Negative Channel connected to Vss

There is a value of +2 to +5 millivolts between ground and wiper of pot when the readout is near zero or as I recall to be 18 digital value for near zero, then reverts to reading up to about 15,000 at wiper zero voltage.

Read the A/D errata on page 3 of the 18F46K80 errata sheet:
http://ww1.microchip.com/downloads/en/DeviceDoc/80519b.pdf
Does the errata explain your problems with the A/D ?
