Ok,the character table I have. what I understand is that this table store in the EEPROM of my microntroller (PIC18 or ATMEL), to be called at the time of selection of characters, and to call all the characters need to read the entire table from eeprom. and show display characters that meet in my resolution, but I do not understand is how to make character displacement and the selection of the same.

{0x7e,0x11,0x11,0x11,0x7e,0x00 }, // A
{0x7f,0x49,0x49,0x49,0x36,0x00 }, // B
{0x3e,0x41,0x41,0x41,0x22,0x00 }, // C

Sorry, for the inconvenience.

Thank you

Yes you can store whole table in EEPROM, or in RAM, but IMO best way is to store it in FLASH, because of it's size and then you can allocate whole EEPROM for written text storage.
In AVR-GCC that should look like..

Code: Select all
static unsigned char my_data[3][6] PROGMEM =
{
{0x7e,0x11,0x11,0x11,0x7e,0x00},   //A
{0x7f,0x49,0x49,0x49,0x36,0x00},   //B
{0x3e,0x41,0x41,0x41,0x22,0x00},   //C
};

To select characters, index variable is assigned, which is increased or decreased by 1 as you press left/right key on remote. So, index var with value 0 corresponds to A, 1 is B, 2 is C, and so on.. Pointer to char is then calculated as:
Code: Select all
char_pointer = index_var * 6 + table_first_byte_address;

The whole concept of rendering graphics is a bit more complicated to explain than that, but it's enough to say that to create illusion of endless turning "wheel", it has been created from 4 parts, i.e. lookup table is rendered 4 times from different positions, the rest is math.

@mbruck: ne, nema posta o prethodnom satu. O zračnom trafu, kao i shema ima TU. Prema tome sam prvo i radio, ali nisam uspio izvući neku struju iz toga, pa sam neko vrijeme eksperimentirao sa flyback topologijom, ali sam se na kraju vratio na početak, malo modificirao, te pažljivije odabrao komponente.
Nije neka tajna, evo kako izgleda:

Ovo 100 i 110 zavoja za prim i sek je odprilike jer ne brojim, nego namotam koliko stane u 2 sloja, dakle do dole, pa natrag i to je tu negdje koliko sam napisao.

Nema potrebe jer napon izgleda pitomo.

Druga stvar da nema ovog 47nF konda. Onda to izgleda ovako:

Špica ide gore jako jako daleko, ali je odrezana na 60V jer je to upravo probojni napon IRFR1018. :D Tada se hajca poprilično, al neće da popusti. :twisted:

Hello Kizo

How you did with the calculations of the solenoids?
as you found the number of turns?
the secondary coil current?

"Mutual induction of two cylindrical solenoids", so is called the induction

thanks for the help Kizo

Bonjour, je suis Français et je ne comprends pas le Croate, donc, j' utilise Google pour la traduction, merci de votre compréhension. Il ya longtemps que je voulais réaliser une telle horloge, la votre est superbe!
félicitation pour cette réalisation. Voulant la réaliser, je me suis aperçu qu' il n' y à pas les plans des PCB et le programme, ma demande : est-il possible d' avoir ces documents pour réaliser cette horloge magnifique!
Merci de votre réponse. Cordialement.

Pozdrav, ja sam francuski i ja ne razumijem hrvatski, dakle, sam zapravo koristiti Google za prijevod, hvala vam na razumijevanju. Davno sam htjela napraviti takav sat, tvoj je super!
Čestitke za ovo postignuće. U želji da, shvatio sam da je don 'ne planira PCB-a i program, moje pitanje: je li moguće da su te dokumente kako bi ovaj prekrasan sat!
Hvala Vam na odgovoru. Srdačno.

Hello, I am French and I do not understand Croatian, therefore, I actually use Google for the translation, thank you for your understanding. Long ago I wanted to make such a clock, yours is superb!
congratulations for this achievement. Wanting to make, I realized that he don 'no plans to PCBs and the program, my question: is it possible to have these documents to make this beautiful clock!
Thank you for your response. Cordially.

sve pohvale majstoru, odlično odrađeno, našao sam na nešto slično na internetu pa ako nekog zanima mogu okačit ostatak.....evo sličica!

mislio sam nešto ovako pravit ali sad kad je kolega napravio i provjereno radi....predomislio sam se.

@Kizo, svaka čast :!:
Ne znam kako sam se našao ovdije, ali drago mi je da sam "zalutao" i vidio ovaj projekat :D

Hi all. Already collected two clocks, one on the pic16f628, other on atmega32. But in some and in others has its drawbacks. Kizo version is far superior to the watch I have already collected. Nowhere on the website did not find any circuits or firmware. It is the author's secret, or the author can still lay out the circuit and firmware? I will be grateful thanks.
Привет всем. Уже собрал двое часов, одни на pic16f628, другие на atmega32. Но и в одних и в других есть свои недостатки. Версия Kizo намного превосходит те часы, которые я уже собрал. Нигде по сайту не нашел ни схем, ни прошивок. Это авторский секрет, или автор все-таки может выложить схему и прошивку? Буду премного благодарен.
