Van egy tök jó 3 részes cikk erről. Nulláról a robotokig a címe. Abban minden le van írva.

Rendben, köszönöm szépen a segítséget!
További szép estét nektek!

Sziasztok!

Szeretnék segítséget kérni Tőletek, mert kezdem feladni a dolgot. Egy nixie óra alapot terveztem át, és a programját Haver próbálja fejleszteni. A fejlesztés során felhasználásra került a PDG és PGC láb mint kimenet. Azóta a csatolt videón látható hibát produkálja. Nem jövünk rá miért. Van ötletetek? Ez a program az alap hardveren ugyanezt a hibát produkálja ezért nem hardveres hibára gondolok.

Előre is köszönöm a segítséget.

Kacsolási rajz és forráskód nélkül erre aligha lehet mit mondani.

Sajnos nincs kapcsolási rajzom Azt nem kaptam hozzá. PIC18F452 hajtja a 6 db 74141-et direktbe, nem multiplexelt. Mivel eredetileg csak órát mutatott így nem volt a meghajtók minden lába bekötve, viszont Én szeretnék dátumot is, így minden vezerlő, minden lába be lett kötve. Ez viszont csak a PGD és PGC lábak felhasználásával sikerülhetett. A forrást szívesen küldöm ha kell.

Sziasztok! Kicsit off leszek. Ha véletlenül vannak itt oldschool hobbisták munkakeresés közepette, és nincs nagyon ellenükre a C programozás, egy életjelet kérnék tőlük. Dióhéjban összefoglalva ezért. Köszönöm a figyelmet.

Szia!
Szerintem látatlanban a hiba az, hogy a kijelző nem másodpercenkét van módosítva, hanem sokkal többször, ez eleve nem jó, és ráadásul egy megszakítás, vagy egyéb programozási hiba miatt szemét adat kerül kijelzésre. Ha nem hadititok, akkor a forráskódot tedd fel ide, vagy rajzold vissza a panelt (kb 1 óra munka) és akkor lehet akár egy új programot is írni,vagy a hibát megtalálni.
A PGD és PGC lábak nem lehetnek a hiba forrásai.

Hello everyone, I need help, I have a project "Remote controlled fan regulator" using pic microcontroller, I downloaded from hamradio.in,project is working fine when using given hex file, but I tried to convert hex from "c" in mplab, but I failed to convert "c" to hex, I am weak in software, please help me,
file attached here:
link of the project is:
https://www.hamradio.in/projects/remote-controlled-fan-regulator-with-timer

Hello! What error message(s) did you got?

error is attached here:

Line 133 of main.c: READ_OSCCAL_DATA() not defined function taken a function returning one integer value. Has to be defined somewhere.
Line 142 of main.c: OPTION not defined symbol. The symbol of OPTION register is OPTION_REG.

Hello Hp41C Mr. Generous, you help me once again, dear I am very weak in coding, kindly make the changes in main.c, I will be really appreciate,
Thank you for your response.

Hi,
the line 142 of main.c should be modified to:

Since READ_OSCCAL_DATA() not devined it should be replaced with code form datasheet.

If the retlw instruction at the last address of program memory not kept the program vill not start.

Dear I change the code as you said,then some errors appears :

Project can be compiled with xc8 compiler without issues.

ok, I will try soon

Dear Mr. genius, please upload the source code with necessary changing, which will running successfully without error, in the mean time, I trying to learn how to use xc8, as I told you already that I am weak in software.
Thanks in advance

Dear as I tried to compiled in xc8 ,I found 6 errors as attached below:
1. file no.1,with changes told by you 6 error.
2. file no.2. without any change 4 errors.

Hi,
first of all, this program was written in 2010 - 2011, so it is better to use the old IDE form Microchip (the MpLab8) and an old version of xc8 (in my case V1.33). Sorry the syntax has changed sinse then.

Dear friend Hp41C, I run the code successfully now, you are really great, you are helping others without any personal benefit,
one more question please, this code is used for Remote address : 0xff00,
I need to change the address of remote, but don't know where is address of remote written, I know the commands only, that was written in remote_commands file, but don't know about address,
Thanks,
Thanks,
Thanks,
and again Thanks,
Naresh Jain,

Hi,
according this page, NEC remote protocol shifts the 8-bit address and its complement in the IR telegram. The program stores them in IrData structure.
in line 238 of main.c this statement can be found:

If the constatnt is changed, the decoded address would change as well.
For examle>

This line modifies the address to 0x18 (24 in decimal).
The address may be in the other half on data, so it can react to address 0xE7 (231 decimal).

as mine remote having address is : 0x7FD80,
then you means address would be:
1. if ( IRData. byte0 == 0x80 ) // Address is zero


This line modifies the address to 0x80 (128 in decimal).

The page last linked states the address of a device with NEC IR remote control has only 8 bit of ddress.

Thank you very much, i want, i gift you somthing ,how can i gift you

Dear friend, have you successful and simple circuit with rtc of wand clock

Dear respected friend, I have successfully running code for AT89C2051 to control the speed of two fans upto 10 levels and four lights turns on/off with remote , I need modification, I want when I switched on the fan or change the speed level then fan should start at full speed for 3 seconds

Hi,
keep the speed information of motors is GPRs, after a speed contorol packet received, store new speed code in GPR but set motor out at full speed, start a timer (3 sec). Whec the time elepsed modify motor out to the stred speed.

Dear, I can not understand , I upload the code here,I used the nec remote to control,please check :

hp41c's very busy person , I think nobody can solve my problem

Dear friend will you solve my problem
