Was necesary only to set the port RA.5 as output . Its iteresting that portA5 work well as digitall output pin but did'n work as PWM pin only if its set to output.
Thank you...
Hi,
HPWM work right on PORTA.1 . Also , the PORTA.5 work well like a digitall port.
I want to move the PWM1 from PORTA.1 to PORTA.5 . Theoretically is very simple, must set APFCON.0 =1 .
Now I...
100% 16f1847 work at 3,3v , I worked many time.
Tumbleweed, with PK2 or PK3 you can't programm 18FxxK40. ( read here :https://www.microchip.com/forums/m1011325.aspx ) . A simple way for standalone programmer is upgrade to PicKitPlus (...
The file "PK2Devicefile.dat" have not edited the microcontroller type. Use DEVICE EDITOR software from here https://sites.google.com/site/pk2devicefileeditor/ and here is the Device ID PIC's
Sometimes I read this topic but when I needed it I did not find it ...I dug after him a few hours, so thousands thanks to all for help !
Now its clear for me.
Thank you very much for your patience and explanation !!
Thank you very much Richard !
Now I see that 100 iterations overflowing a word var, so I'll use 10 iteration or DT Average routine, but nevermind right now.
I know it's unpleasant to ask...
I work on proffesional PCB, I changed the capacitor, but the same problem. So, nevermind, without 100nF capacitance the AN0 is ok. Anyway is strange whats what happen there.
On AN0 I read the...
Thank you Ioannis for your effort ! .. you spend a time for me. The problem is solved, I don't understand what happened really.
So, on AN0 I had a TC1047 ( analog temperature sensor ) with a 100nF...
Now I readed the some value on AN2 with succes, but AN0 is the same.
Thank you for your fast reply !
I tried your version, but don't work. The readed adc values oscilating from 10x to 22x.....
Hi to all,
I have troubles with reading 10 bit on AN0 , too .
Can somebody give me some ideas, please ?

Hello Fratello,
Sounds like a hardware issue. I worked with LM2931 and i had some strange problems because I used a lower capacitance on output. Connect a 100uF (0,1uF is too low) near the stab...
Try to install MPLAB 8.92
Thank you very much Art ! All its ok, now is working perfectly.
I adjusted the value, now the pulse on all chanells have 1,5mS

I decoded a PPM signal from a old RC receiver with a shift register(HC595) with succes, but short noises cause random output on all channels , so was not a good ideea.
Also I tried to decode a PPM...
May be I'm wrong, but verify if you have a shortcircuit between pin3 and pin6 from LCD (Vo pin and E pin)
Now all are ok! The problems was from lookup table, was missing one value.
Now all are ok !
SOLVED !
1000 x thanks , HENRIK
I modified the the loockup table :
lookup value ,[30,40,50,65,80,90,100,117,136,153,168,180_

Thank you very much for explanation , Henrik....

The pulses are 100% ok , I verified with a osciloscope,

If I turn on the pic with signal>185 then duty = 0 ; then I reduce the signal value under 185 , then duty=divf
