Re: TMR0 Pic 12F615

Thank you Benj, TMR0=0xFF it is, as you said, to reset the counter to 0 when overflowing. I tried without the C code and it's the same. It is incredible because this program work before, and it seems to me correct! The interrupt is on A2 (this is the external "clock" input, it is the signa...

TMR0 Pic 12F615

Hello Benj, Everyone, I have a problem that I can not solve with the attached program, which was running Flowcode 7 I think or maybe 6 (I don't remember), whatever, it worked. Lately I opened it under Flowcode 8.1.1.11 and compiled, since it doesn't works (in simulation under Proteus) the displayed ...

Re: DS18B20 with PIC18F26K22

Hello Benj, Thank you very much for your answers. I am sorry for this delay, I prepared, and now I am on an exhibition to present my products. It is very tiring ! I bought the XC8 compiler, 2 years ago and I use it every time. I tried to change the config 0x1; 0x2 and the OSCCON parameter. I calcula...

DS18B20 with PIC18F26K22

Hello everyone, I have a big problem with the operation of the DS18B20 and the PIC18F26K22. Usually I use a PIC 16F1829 with an OSCCON F0 configuration (32MHz) PLL enable and clock Flowcode at 32MHz and it works fine. Now I changed Pic for reasons of use of additional inputs and outputs, but here it...

Re: Write float value in eeprom

Thank you Benj,
I will try the first solution.
As for the second that you propose, I tried in C but I was not successful, during the compilation I got a lot of errors. Do you have an example (under the elbow).

Write float value in eeprom

Hello Benj,All, I would like, for reasons of precision, to be able to memorize in the EEPROM for example a value U = 4.9542 I tried by creating a 16-bit shift variable, with a variable U as Integer MSB = U >> 8 LSB = U => EEVAL = (MSB << 8) + LSB eeprom1::write(0,MSB) eeprom1::write(1,LSB) It works ...

Re: Delay, Timer

Medelec,
Forget all, sorry, I confused all.
But for a delay of 8 hours, if I set the timer 2 the minimum frequence is 122.070
for 8 hours 122.07 x 3600 x 8 =3515616
it is too much for the counter

Re: Delay, Timer

Hello Medelec thank you for this answer, I understand the role of the interruption, by cons if I have a main program that runs at 32 MHz (for example OSCCON 0xF0 for the 16F1829) and I want to involve this delay triggered by an interruption every 15.259 Hz (OSCCON 0x38), I can not mix the 2 OSCCON, ...

Re: Delay, Timer

Benj, I watched the demo you added. the OSCCON is settled: SCS = Oscillator Timer 1; IRCF = 31 KHz; SPLLEN = 4 x PLL disabled I do not understand : the interrupt frequency you wrotte at 15.259 Hz instead of 31 KHz; the timer is disabled (perhaps to avoid calling a macro, only for the demo). Do I hav...

Re: Delay, Timer

Thank you very much Benj for all In my question, about 8, I forgot to add "Hours". Yes I wonder how one can manage to count several hours, knowing that at the bottom, in general, with a prescaler at 1 the frequency of interruption is around 125 Hz => 125x3600x8 = 3600000. Sorry Benj for th...

Delay, Timer

Hello All my question is about timers. If I want, for example, to turn on the backlight of an LCD for 2 minutes, by pressing a push button and otherwise the main program continues to run. I imagine that I can bring in a timer (interupt), but if the delay should last 8:00, how can I (PIC 16F1829). Th...

Re: PIC 18F26K22

thank you very much Martin, I finally understood!
I need time, but now it's ok.
I will follow your advice and avoid using divisions and multiplication
the bit shifting will do the trick.
Many thanks a new time

Many thanks Martin, For the osccon that's OK, thanks. but for the EEPROM, I took a look at the thread and I don't understand, because you wrote : ByteHigh = (IntValue/ 256) ByteLow = IntValue - ByteHigh* 256 for exemple, IntValue = 1000; ByteHigh = 1000/256 = 3.9; ByteLow = 1000 - (3.9*256) = 0.
