An buga lambar tushe don tashar tashar Doom don wayoyin tura-button akan guntuwar Spreadtrum SC6531. Canje-canje na guntu na Spreadtrum SC6531 sun mamaye kusan rabin kasuwa don wayoyi masu arha na turawa daga samfuran Rasha (sauran na MediaTek MT6261 ne, sauran kwakwalwan kwamfuta ba su da yawa).
Menene wahalar jigilar kaya:
- Babu aikace-aikacen ɓangare na uku da ake samu akan waɗannan wayoyi.
- Karamin adadin RAM - megabytes 4 kacal (alamomi/masu sayarwa sukan lissafta wannan a matsayin 32MB - amma wannan yaudara ce, tunda megabits, ba megabytes ba).
- Rufaffiyar takaddun (zaku iya nemo ɓoyayyen sigar farko da mara kyau kawai), don haka an samu da yawa ta amfani da injiniyan baya.
Guntu yana dogara ne akan na'ura mai sarrafa ARM926EJ-S tare da mitar 208 MHz (SC6531E) ko 312 MHz (SC6531DA), na iya saukar da agogo zuwa 26 MHz, ARMv5TEJ processor architecture (babu rarraba da kuma iyo).
Ya zuwa yanzu, kawai an yi nazarin ƙaramin ɓangaren guntu: USB, allo da maɓalli. Don haka, kawai kuna iya yin wasa tare da haɗa wayarku da kwamfutar ta hanyar kebul na USB (ana canja wurin kayan wasan daga kwamfutar), kuma babu sauti a cikin wasan.
A halin yanzu tana aiki akan wayoyi 6 cikin 9 da aka gwada bisa guntuwar SC6531. Don sanya wannan guntu cikin yanayin taya, kuna buƙatar sanin maɓallan da za ku riƙe yayin taya, maɓallan don samfuran da aka gwada: F+ F256: *, Digma LINX B241: cibiyar, F+ Ezzy 4: 1, Joy's S21: 0, Vertex M115: sama , Vertex C323 : 0.
An kuma buga bidiyo biyu: tare da zanga-zanga wasanni a waya da ƙaddamarwa akan 4 ƙarin wayoyi.
PS: An buga irin wannan abu akan OpenNet, labarai daga gare ni, mai kula da rukunin yanar gizon ne kawai ya gyara shi.
Ba tare da lasisi ba, yana da wuya a faɗi abin da lasisi ya kamata ya kasance don lambar da aka samu ta hanyar injiniya ta baya, la'akari da shi azaman haƙƙin mallaka - kwafi da canzawa, bari wasu su canza shi.
An yi amfani da wasan Doom don jawo hankali, a matsayin misali, Ina son firmware kyauta don wayoyi masu fasali. Kwayoyin su sun fi ƙarfin abin da ake amfani da su a cikin firmware. Haka kuma, kayan masarufi suna da arha kuma sun yadu, ba kamar wayoyi da ba kasafai suke da “bude” OS ba ko kuma wadanda ke ba ku damar gudanar da lambar ku. Ya zuwa yanzu ban sami wanda zan yi aiki da shi ba, kuma injiniyan juzu'i yana da daɗi. Kyakkyawan wurin farawa shine nemo sarrafa katin SD da sarrafa wutar lantarki ta yadda zaku iya amfani da waɗannan wayoyi azaman na'urar wasan bidiyo. Baya ga Doom, zaku iya tashar tashar NES/SNES emulator.
