Ahoj Michale <br>
<br>
Opravuji se ten RSTB nedela cely reset ale jen reset dekoderu.<br>

Ahoj Michale<br>
<br>
To RTS dela /RESET citacu pro cteni a mechaniky. Ma to delat to,
ze pri log0 mechanika nechava hlavicku na zacatku media a az potom
co se to da do log1 se zacne hlavicka pohybovat.<br>
<br>
RXCA je opravdu signal hodin pro prijem znaku. Mel by jsi tam
videt frekvenci 101,562 kHz. Prijem funguje tak, ze RAW signal z
mechaniky se synchronizuje do casove domeny radice. Pak se
synchronizuje s vnitrnim generatorem frekvence co vychazi z
oscilatoru 6,5MHz. Pak to jde do dekoderu a z nej vychazeji dva
vodice. Jeden jsou ty hodiny RXCA a druhy jsou data na RXDA.<br>

<p><font size="+1">Ahoj,</font></p>
<p><font size="+1">potreboval bych se ujistit, zda dobre rozumim
zapojeni SIO v QD radici. Jde mi konkretne o kanal B, kterym
se pres DTR (zapis do CTRL 7. bit) spousti motor. Ovsem k
cemu tam slouzi signal RTS </font><font size="+1"><font
size="+1">(zapis do CTRL 1. bit)</font>? <br>
</font></p>
<p><font size="+1">Jde to do nejake logiky, ktera je pak
pripojena na RXC kanalu A. Podle datasheetu k SIO se jedna o
Receiver Clocks - predpokladam tedy, ze aktivaci RTSB se
rozkmitaji hodiny, ktere rikaji kanalu A casovani toho, jak
ma scanovat prijem dat z QD.</font></p>
<p><font size="+1">Pokud jsem to identifikoval spravne, tak by
mne zajimalo k cemu je to dobre? Myslim tim to samostatne
ovladani toho signalu RXCA. Nebylo by lepsi mit to ovladane
rovnou s motorem? <br>
</font></p>
<p><font size="+1">Predpokladam spise, ze mi neco unika...</font></p>
