16F15223 Configuration issue

[tumbleweed]

In Osc_Init_32MHz(), shouldn't the setting for OSCEN be

Code Select Expand

  OSCEN = $40        'HFINTOSC is explicitly enabled, operating as specified by the OSCFRQ register


[okmn]

nothing change  with  OSCEN = $40

Proc Osc_Init_32MHz()
    OSCEN = $40'00
    OSCFRQ = $05                                ' FRQ 32MHz
    OSCTUNE = $00
EndProc

it is alrady one led blinking  (1s)   other led  no blink (500ms)
problem looks timer0 can not setup.

It can't go to Timer0's interrupt at all, so even if it goes there once, it will turn on the led in the interrupt and turn it off the next time it goes... but it doesn't even turn it on.

Hi,
Looking on phone so not easy but I think you should put interrupt code above and a jump over it. As you have it in the middle of everything.

I think you need something like this but havent got Positron on tablet.

I don't think the problem is in the source because the same program from 16f15223 works on 18f26k40 as seen in the Proteus demo.

[okmn]

yes  it is works also for 16F15323  too.(i tested)

it has something! for 16F15223

[RGV250]

Hi,
Have you compared the PPI files / datasheets of the 2 to see if there are any differences?

I have just had a quick look and 16F15223 is not supported, If you look in the compiler where the Device =  line is. Device = 16F15323 text goes blue in the declare line but the 15223 does not.

Bob

[tnencon]

The compiler supports PIC16F15223. Otherwise, the compilation process would not occur.

[RGV250]

Hi,
Interesting, what version are you using as it does not on mine. 4.0.3.8

Bob

[Stephen Moss]

@RGV250 the 16F12223 is supported in 4.0.4.2, so if want it you would have to pay to update to the latest upgrade as that came in at 4.0.4.0, which unless I am missing a file from my collection appear to be the next version released after 4.0.3.8.

[RGV250]

Hi Stephen,
I never use 16 series, I was just trying to help the tread which due to the issue appears to be a PPI / configuration issue.
Thanks for letting me know though.

Bob

[top204]

Make sure you are actually using version 4.0.4.2 of the Positron8 compiler, because this corrected the config fuses for the newer enhanced 14-bit core devices added in the upgrade. Press the F2 button in the IDE and look at the top comments in the assembler file and it will tell you the compiler's version and who it is registered too.

I have attached a demonstration program of the PIC16F15223 operating a Timer0 overflow interrupt using a more structured approach and using a Timer0 library that has the commonly used Timer0 SFRs in it, and meta-macros to make them simple to use, and easier to follow in the main program listing. It also has a mechanism for creating the Timer0 value for a specific interrupt time interval.

The demo code listing is below, but it also uses the "Timer0_16Fxx223.inc" file that is within the attached zip file. I do not have a PIC16F15223 device, but according to the datasheet it should work OK, and I have used the same mechanisms and meta-macros on many other devices, but with modified SFRs and bits to suit the device used:

As you can see, it is more structured and easier to read and understand.

With a timer interrupt, always clear its interrupt flag at the end of the interrupt's code, otherwise, the timer's flag could set again before it is finished. Remember, a timer does not automatically stop while its interrupt is called and being used. The same for the timer's re-loading value (if there is one). This should be loaded at the end of the interrupt's code, just before its flag is cleared.

Viewing the config fuses for the above program (as in the image below), they are correct, and that is what the update's correction were for. The attached file is named: "16F15223_Timer0_Interrupt.zip", and make sure the "Timer0_16Fxx223.inc" file stays in the same folder as the program listing including it:

[tumbleweed]

because we need to return to bank zero to assign intcon

INTCON is part of the Core Registers, so it's accessible with any bank select setting.
Changing banks isn't necessary.

From the datasheet:

The core registers contain the registers that directly affect the basic operation. The core registers occupy the first 12 addresses of every data memory bank

[top204]

As tumbleweed stated, certain SFRs are in bankless RAM and the compiler is well aware of this so does not add unrequired RAM bank mnemonics.

For example, the RAM bank setting function for enhanced 14-bit core devices in the compiler uses the code below for placing the RAM bank mnemonic, after it has checked other things as well:

Code Select Expand

if(((Bytein_Address >> 7) != Global_Previous_RAM_Bank) && ((Bytein_Address & 0x7F) > 0x0B))
    {
        movlb(Bytein_Address >> 7);
        Global_Previous_RAM_Bank = Bytein_Address >> 7;
    }

See that it first checks whether the previous RAM bank setting is not the same as the one being looked at, and that the variable or SFR it is examining is not in bankless RAM, before issuing the movlb mnemonic and setting its internal variable for the current RAM bank it is in.

More optimised RAM bank manipulation has been with the 8-bit compiler since I started writing it all of those years ago, and is one of the things that makes the assembler code so optimised, and not just full of unrequired bank setting mnemonics on any device type, as some other compilers do.

As you can see, it is more structured and easier to read and understand.

With a timer interrupt, always clear its interrupt flag at the end of the interrupt's code, otherwise, the timer's flag could set again before it is finished. Remember, a timer does not automatically stop while its interrupt is called and being used. The same for the timer's re-loading value (if there is one). This should be loaded at the end of the interrupt's code, just before its flag is cleared.

Viewing the config fuses for the above program (as in the image below), they are correct, and that is what the update's correction were for. The attached file is named: "16F15223_Timer0_Interrupt.zip", and make sure the "Timer0_16Fxx223.inc" file stays in the same folder as the program listing including it:

Thank you Les,

i tried it  but only LED1_Pin (RC0) is blinking (i also checked by oscilloscope.)

Make sure you can actually use PORTA.2 for an output on this device. It may need an SFR's bit changing that has not been noticed in the datasheet.

yes i am sure.
Pin 11 (RA2) logic status no change
it's always 0 (npn transistor "base" pin connecting)
The transistor is also no failure

because we need to return to bank zero to assign intcon

this is bad

nothing change.
 only rc0 blinking.

Try replacing the line:

T0CON1 = %01010010

with

T0CON1 = %01000000

You will find it in the Timer0_Init procedure.

It seems as though I forgot to change that SFR's contents and it is set for a PIC18F26K40 device's Timer0 overflow and will actually syncronise the Timer0 and not allow it to work correctly on a PIC16F15223 device. I wish microchip would leave peripherals alone that do not need changing, and at least keep SFR bit settings as standard.
