Bayakwazi ukujongana nentshabalalo kwiselfowuni esisiseko
I-Doom inike ukuthetha kwakhona kwaye kukuba kweli nqaku siza kuthetha ngeprojekthi entsha ngalo mdlalo oye wakwazi ukufikelela kwiindawo apho umntu angazange acinge. Kwaye kungenxa yokuba, ngenxa yomzamo kunye nokuyila kwabadwelisi benkqubo abaninzi, intetho ethi "Ukuba inesikrini, ineDoom" isiwe kwinkcazo yayo ephezulu.
Iprojekthi esiza kuthetha ngayo namhlanje yinxalenye ye Iprojekthi yeFPDoom kwaye apho into entsha kukuba izibuko Intshabalalo yeefowuni ezisisiseko ezisekwe kwitshiphu ye-Spreadtrum SC6531.
Kwabo bangaziyo ngeDoom, kufuneka bayazi loo nto Igqalwa njengomnye wemidlalo yevidiyo engoovulindlela yomntu wokuqala. ngokwazisa, kwiminyaka yeekhompyuter ezihambelana ne-IBM, amanqaku anoveli afana nemizobo ye-3D, indawo ye-XNUMXD, umdlalo wenethiwekhi yabadlali abaninzi, kunye nenkxaso yemod.
Ikhowudi yomthombo weDoom yakhutshelwa uluntu nge-23 kaDisemba 1997. Nangona iDoom yayidalelwe iDOS ekuqaleni, ukukhutshwa kwakuyeyenguqulelo yeLinux kwaye ikhowudi yomthombo kwafuneka ibuyiselwe kwiDOS kunye nezinye iinkqubo zokusebenza.
Ikhowudi yonikezo yapapashwa kuqala phantsi kwelayisensi yobunini ethintela ukusetyenziswa kwezorhwebo kwaye ayifuni ukuba abaphuhlisi babonelele ngekhowudi yemvelaphi yohlengahlengiso abayipapashe ngendlela ephunyezwayo. Ukusukela namhlanje, uninzi lwamazibuko eDoom yimithombo evulekileyo.. I-GNU GPL ifuna ababhali abasebenzisa ikhowudi ye-GPL kwisoftware yabo ukuba nabo bakhuphe ikhowudi yemvelaphi elungisiweyo.
Umbono wokuzisa iDoom kula maqela kungenxa ukuya kolunye uhlengahlengiso lwetshiphu ye-Spreadtrum SC6531 nangaphezulu kwayo yonke loo nto ezi zithatha malunga neentengiso ezininzi zeefowuni ezisisiseko eTshayina, eRashiya nakwamanye amazwe.
Itshiphu isekwe kwiprosesa ye-ARM926EJ-S. kunye ne-frequency ye-208 MHz (SC6531E) okanye i-312 MHz (SC6531DA), i-architecture ye-ARMv5TEJ processor. Kwaye nangona zonke zivakala zilungile kakhulu, kukhankanyiwe ukuba izibuko linobunzima obuphezulu bokuhamba kwaye kungenxa yezi zinto zilandelayo:
- Akukho zi-apps zomntu wesithathu ezikhoyo kwezi fowuni.
- Isixa esincinci se-RAM: kuphela i-4MB (iimpawu / abathengisi bahlala bedwelisa oku njenge-32MB, kodwa oku kuyalahlekisa njengoko bebhekisa kwi-megabits, hayi i-megabytes).
- Amaxwebhu avaliwe (unokufumana kuphela ukuvuza kuguqulelo oludala nolusezantsi), ngoko ke kuninzi kwatsalwa kusetyenziswa indlela yobunjineli ebuyela umva.
Okwangoku, kuphela inxalenye encinci yetshiphu ephandiweyo: I-USB, isikrini kunye nezitshixo, ngoko unokudlala kuphela kwifowuni eqhagamshelwe kwikhompyuter ngentambo ye-USB (izixhobo zomdlalo zidluliselwa kwikhompyuter), kwaye akukho sandi kumdlalo.
Ngendlela yayo yangoku, umdlalo ukhutshwa kwiifowuni ezi-6 kwii-9 ezivavanyiweyo ezisekelwe kwi-chip ye-SC6531.
Uyifaka njani iDoom kwi-SC6531?
Ku Unomdla wokuvavanya iprojekthi?, unokulandela imiyalelo yokwakha ekwabelwana ngayo kwi ukulandela ikhonkco.
Ukubeka le chip kwimowudi yokuqalisa, kufuneka wazi ukuba sesiphi isitshixo omawusibambe ngexesha lokuqalisa (kwimodeli ye-F+F256 eli liqhosha elithi “*”, le-Digma LINX B241 – iqhosha “eliphakathi”, le-F+Ezzy 4 – iqhosha elithi «1», leVertex M115 – «phezulu», le-Joy's S21 kunye ne-Vertex C323 – «0»).
Ukuqhuba umdlalo kukhankanyiwe ukwenza uvimba weefayili osebenzayo kwaye ubeke ifayile yesixhobo seDoom apho, umzekelo doom1.wad kuguqulelo lweshareware lweDoom 1.
Emva koko, le miyalelo ilandelayo kufuneka yenziwe kwiscript kwaye emva koko uqhagamshele ifowuni:
./spd_dump --wait 300 fdl nor_fdl1.bin 0x40004000 fdl fpdoom.bin ram cd workdir && ../libc_server -- --bright 50 --rotate 3 doom
--eqaqambileyo i-X kukuqaqamba kwesikrini sefowuni (X = 0..100).
--jikelezisa i-S[,K] yikhusi/ibhodi ejikelezileyo kwiiyunithi ze-90 degrees (-1 okanye 3 = -90, 1 = +90, njl.)
Kukhankanyiwe ukuba zonke izikrini ze-LCD zolu hlobo lweefowuni zithe nkqo, ke ukuba isixhobo sakho sinesikrini esithe tye, oko kuthetha ukuba sisikrini se-LCD esithe nkqo esibekwe ngokuthe tye, kufuneka kusetyenziswe amaxabiso e-S kunye no-K ahlukeneyo.
Ukongeza koku unokongeza iinketho ezongezelelweyo zeDoom, umzekelo doom -timedemo demo1.
Gqibela ukuba unomdla wokwazi okungakumbi ngayo malunga neli zibuko, kunye noluhlu lwemizekelo ehambelanayo, ungajonga iinkcukacha Kule khonkco ilandelayo.
