Quote from: okmn on Jun 04, 2024, 02:02 PMthe problem is timer0 interrupt issue
we could not see any led blinking still by using timer0 16bit

Did you try:

- 8-bit Timer0
- Fosc/4 instead of HFINTOSC
- Timer1

i had been tried this ;
Fosc/4 instead of HFINTOSC
same problem persists

I will try other tests later.

I have simulated the program in mplabx with pic-as and it works with the following values
 
T0CON1 = $45
TOCON0 = $90

hi Pepe,

only Blink_Led_2 is blinking

Toggle Blink_Led_1 is not blinking.

Could you be so kind as to try the 2 hexs files again?
to determine if the interrupt is executed every 10ms

Hello okmn,

can you try this ISR code where instead of toggling the LATA.2, it is being read first and then changed:

Context Save
    If PIR0bits_TMR0IF = 1 Then   
        PIR0bits_TMR0IF = 0
        TMR0H = $F6
        TMR0L = $3C
        Inc Ten_MilliSeconds
        If Ten_MilliSeconds = 50 Then
            Ten_MilliSeconds = 0
            If LATA.2 = 1 Then
                LATA.2 = 0
            Else
                LATA.2 = 1

to determine if the interrupt is executed every 10ms

interrupt not runed,
 
only one led blinking it is in do--loop

Quote from: trastikata on Jun 06, 2024, 04:43 AMHello okmn,

can you try this ISR code where instead of toggling the LATA.2, it is being read first and then changed:

Code Select Expand

Context Save
    If PIR0bits_TMR0IF = 1 Then   
        PIR0bits_TMR0IF = 0
        TMR0H = $F6
        TMR0L = $3C
        Inc Ten_MilliSeconds
        If Ten_MilliSeconds = 50 Then
            Ten_MilliSeconds = 0
            If LATA.2 = 1 Then
                LATA.2 = 0
            Else
                LATA.2 = 1
            EndIf
        EndIf           
    EndIf
Context Restore

only the led in do-loop is blinking

Timer0 16bit inerrupt rutine looks not enable/run (Although we write the relevant commands)

Try setting the timer to run in async mode (T0CON1.ASYNC = 1)

try again

Leds.hex is ok. 
2 led are blinking

Pepe, can you share the source code of the Leds program?
Thanks

If the program I attached works well, then I have been able to determine what the error is why when it is compiled with positron it does not work and when it is compiled with ccs it works correctly.
I await your response okmn.
Thank you.

Green color led is RC0
Red color Led is RA2

Indeed the problem was what I thought, you will have to wait for Les to solve it.

Looking at the movlb mnemonic in the assembler listing, it is not being generated correctly as its device value, as posted in the anomaly section.

So.... Looking at the info details about the 16F15223 device, the only thing I could see different was in the "8bit_device.info" file, and it was a difference so subtle, it should not do anything, but it seems it does!

With Notepad.exe only, open the "8bit_device.info" file at "C:\Program Files (x86)\ProtonIDE\PDS\Includes\bin8\8bit_device.info\"

And do a text search for <PIC16F15223>.

The line will be:

<PART_INFO_TYPE><15223><PIC16F15223><16Exxx><a><1><7ff><40><7f><0><0-0><0-0><0><5>

So change it to:

<PART_INFO_TYPE><15223><PIC16F15223><16EXxx><a><1><7ff><40><7f><0><0-0><0-0><0><5>

Notice the subtle change of <16Exxx> to <16EXxx>.

Now the movlb mnemonic seems to create the correct device values. i.e:

017E movlb 0x3E

Instead of the incorrect one of:

003E movlb 0x3E

Wow! I've seen some subtle querks in programs, but that one is totally idiotic. Why on earth should a lowercase and uppercase character in a device's type make any difference to the mnemonic code it generates? They are the same device family. i.e. Enhanced 14-bit core devices! However, with microchip, every idiotic thing is possible in their programs. :-)

This should correct the anomaly with the movlb mnemonic and I have just found a 16F15224 that has the same querk, so I will run some tests, and post a new "8bit_device.info" file.

Many thanks for finding the anomaly.

Guys ,
tahnk you so much
16F15223 Timer0 interrupt is ok now 

Green led is RC0
red Led is RA2
