Jednoduch\u00e9 zozn\u00e1menie z FPGA kitmy ktor\u00e9 pou\u017e\u00edvam.<\/strong><\/p>\n

V\u0161etky kity ktor\u00e9 vlast\u00edm s\u00fa zalo\u017een\u00e9 na Altera Cyclone-II. Jedn\u00e1 sa o lacn\u00e9 kity z Ebay.<\/p>\n

Tento \u010dl\u00e1nok je ich jednoduch\u00fdm popisom.<\/p>\n

Ako prv\u00fd je EP2C5\/EP2C8 mini board.<\/strong><\/p>\n

Na Ebay je to najjednoduch\u0161\u00ed FPGA kit a tie\u017e najlacnejs\u00ed. Samotn\u00ed stoji cca 27$, spolu z klonom USB Blasteru cca 37$. Za tieto peniaze dostanete do\u0161ti\u010dku osaden\u00fa EP2C5T144, Konfigura\u010dnou pametou EPCS4 a oscil\u00e1torom 50MHz. Jedin\u00e9 osaden\u00e9 perif\u00e9rie s\u00fa 3ks LED,\u00a0 jedno tla\u010d\u00edtko a RC \u010dlen.<\/p>\n

\"\"<\/a>Podla m\u0148a nieje najlep\u0161\u00ed pre za\u010diato\u010dn\u00edkov. Na druh\u00fa stranu d\u00e1va ve\u013ek\u00fa vo\u013enos\u0165 pri prip\u00e1jan\u00ed perif\u00e9rii. Ja ho vyu\u017e\u00edvam ako z\u00e1klad hotov\u00fdch kon\u0161trukci\u00ed. aktu\u00e1lne mam rozpracovan\u00e9 dva projekty. SSLA (Super Simple Logic Analiser) Co je vlastne len upraven\u00fd k\u00f3d z projektu www.sump.org. Dal\u0161\u00edm projektom je FPGA PC na ktorom mi aktu\u00e1lne be\u017e\u00ed ZX81.<\/p>\n

Par pozn\u00e1mok k tomuto „kitu“.<\/p>\n

    \n
  1. FPGA sa a vymeni\u0165 za v\u00e4\u010d\u0161ieho bra\u010deka EP2C8T144 (Sk\u00f4r ako v\u00fdmenu odpor\u00fa\u010dam n\u00e1kup len PCB a veci si tam osadi\u0165 s\u00e1m.<\/li>\n
  2. Kit je osaden\u00fd 4ks 0R rezistorou (R1,R2,R9,R10). Tieto odpor\u00fa\u010dam odstr\u00e1ni\u0165, s\u00fa nutn\u00e9 len pre EP2C8T144.\u00a0 A znefunk\u010d\u0148uj\u00fa 4 IO porty.<\/li>\n
  3. Ve\u013ek\u00fdm nedostatkom tohoto kitu je fakt ze ka\u017ed\u00fd konektor ma in\u00e9 osadenie nap\u00e1jan\u00ed. Tak\u017ee nieje mo\u017en\u00e9 spravi\u0165 univerz\u00e1lne moduly.<\/li>\n<\/ol>\n

    Druh\u00fd je AC2580<\/strong><\/p>\n

    Toto je kit ur\u010den\u00fd prim\u00e1rne na realiz\u00e1ciu SoC rie\u0161en\u00ed. Obsahuje okrem FPGA, FLASH a SDRAM. Po\u010det perif\u00e9rii je len o m\u00e1lo lep\u0161\u00ed ako pri predch\u00e1dzaj\u00facom kite. V z\u00e1klade s\u00fa 5 tla\u010d\u00edtok a 4 LED. Oscil\u00e1tor klasicky 50MHz. Ale je mo\u017en\u00e9 osadi\u0165 e\u0161te jeden.<\/p>\n

    Kis ta dod\u00e1va v dvoch konfigur\u00e1ci\u00e1ch:<\/p>\n
