rdimmer

[Jann1975]

selline loll küsimus, et ehitan skeemi viimasest arvutikasutajast Rdimmer

ja kuna käepärast on pic16f84a-04 siis asendan selle skeemis olevaga, aga siit küsimus, kas see *.hex fail võib jääda samaks mis originaal või peab seal ka midagi muutma.
...ja nagu aru saan siis tuleb sellele picile juurde veel skeemi resonaator, eks.
ja kas programmeerides tuleb valida siis oscilator HS.

tänud kui keegi lihtsalt lahti seletaks.

[felch]

Ei, nii lihtsalt see asi ei käi. Prosed on sarnased kuid valmis kompileeritud .hex fail ei sobi kindlasti. Võta koodi tekst ette ja tee seal muudatusi ning kompileeri oma prose jaoks.
4MHz kvartsi kasutamisel onn ostsillaatori bitt ikka XT mitte HS (viimane on kõrgema sageduse jaoks).
PIC16F629 on odavam!

[Jann1975]

selge, ostan siis selle pic12f629 aga sinna kriban ju ikka selle HEX faili, või kuidas on õigem öelda?

[felch]

Jah, sinna programmeerid faili sisse. Selleks on sul vaja programmaatorit. Skeeme netis leidub (ja nende juhtsofti samuti). Näiteks ICprog.
Ja kui muidu ei saa, too kivi ning kõrvetan ise.

Felch, hi!
The schematic in AK was with D6 and D5, but on ftp version
D5/D6 are removed....
ftp://ftp.arvutikasutaja.ee/rauakool/Rdimmer/skeem.JPG

so the right version is on ftp true?


Jann1975, hi!
some notes about IC-prog... and JDM programmer... with pic12f629
It is not possible to flash a pic12f629 with JDM original programmer.


you can find some info here:

I`m also trying to build this Rdimmer 8-)

[felch]

Hi!
The most up to date version is in ftp. Use this one.
Diodes were in early versions in order to protect PIC from resetting (i usedreconfigured reset input for voice) if voltage on that pin was higher than 5V. It was sometimes due to coupling capacitor. Now i removed the capacitor and diodes became useless. It wont hurt if you still connect them but ... no need any more.

Btw, where are you from and how did you find this circuit? I mean - AK is in estonian only...as far as i know.

Hi!

thank you for reply 8-)

Yep, AK is in estonian, 8-) and I live here 8-), but my estonian is realllllly bad 8-(, for now, I hope, I will improve it reading your articles in AK 8-) keep going! 8-)

Btw what programmer (hardware/software) do you use?

JDM or Tait clasic or Microchip ICD2 or clone ... http://icd2clone.narod.ru/...
just thinking to build another one.

I use KIT 128 from www.kitsrus.com (self-built but schematics and soft from mentioned page). Very stable and reliable although not so cheap. Of-course one can always use it through COM elliminating FT232, using ICP saves the cost of ZIF socket etc, etc...
