I-SmartDesign MSS
Ukucushwa kwe-SPI
Umhlahlandlela Womsebenzisi
Isingeniso
I-SmartFusion Microcontroller Subsystem (MSS) ihlinzeka ngama-SPI hard peripherals (APB_0 kanye namabhasi amancane e-APB_1) anesandiso sembobo sokukhetha isigqila sendwangu ye-FPGA.
Ukuziphatha kwangempela kwesenzakalo ngasinye se-SPI kufanele kuchazwe kuleveli yohlelo kusetshenziswa i-SmartFusion MSS SPI Driver ehlinzekwe yi-Actel.
Kulo mbhalo, sichaza ukuthi ungazivumela kanjani izimo ze-MSS SPI futhi ufinyelele izimbobo zokukhetha izigqila zendwangu. Ukuze uthole imininingwane eyengeziwe mayelana ne-MSS SPI hard peripherals, sicela ubheke Umhlahlandlela Womsebenzisi we-Actel SmartFusion Microcontroller Subsystem.
Izinketho zokumisa
Ukunika amandla/Ukukhubaza Izimo ze-SPI. Kukhanvasi ye-MSS, udinga ukunika amandla (okuzenzakalelayo) noma ukhubaze isenzakalo ngasinye se-SPI ngokusekelwe ekutheni iyasetshenziswa yini ohlelweni lwakho lokusebenza lwamanje. Izehlakalo ze-SPI ekhutshaziwe zigcinwa ngokusetha kabusha (isimo samandla aphansi kakhulu) ngemva kokusetshenziswa kwekhodi yokuqalisa yesistimu ye-Actel. Izimbobo zangaphandle ze-SPI ezinikwe amandla - ama-MSS I/Os - nazo zilungiswa ngokuzenzakalelayo ikhodi yokuqalisa yesistimu ye-Actel. Qaphela ukuthi ama-MSS I/Os abelwe isenzakalo se-SPI ayatholakala ukuze axhumeke kuma-MSS GPIO uma leso senzakalo se-SPI sikhutshaziwe. Bheka ku- I-MSS GPIO i-configurator handbook ukuze uthole imininingwane eyengeziwe.
I-Fabric Slave Khetha Isandiso. Ungashayela amasiginali wokukhetha izigqila ezifika kwezingu-3 ze-SPI_0 nezingu-7 ze-SPI_1 endwangu ye-FPGA; ukwenza lokhu, udinga ukuphromotha mathupha uye ezingeni eliphezulu imbobo ye-FAB_SS[] ekhona kuzenzakalo ze-MSS SPI ezisetshenziswa kuhlelo lwakho lokusebenza. Ungasebenzisa imbobo ye-FAB_SS ezingeni elilandelayo lokulandelana lapho 'inganqunywa' njengamasiginali wokukhetha isigqila ngasinye.
Incazelo Yembobo
| Igama Lembobo | Port Group | Isiqondiso | I-PAD? | Incazelo |
| DI | Ama-PAD | In | Yebo | Shift idatha ku (inkosi noma isigqila) |
| DO | Ama-PAD | Phuma | Yebo | Kukhishwe idatha ye-serial (ekhiqizwe i-SPI njengomphathi) |
| I-CLK | Ama-PAD | Inout | Yebo | Shift iwashi ngaphandle (ekhiqizwe i-SPI njengenkosi) |
| SS | Ama-PAD | Inout | Yebo | Imbobo yokukhetha izigqila ezizinikele yangaphandle (ekhiqizwe i-SPI njengenkosi) |
| FAB_SS[n:1] | Phuma | Cha | Izimbobo zokukhetha izigqila ezihanjiswa ngokuzithandela (ezikhiqizwe i-SPI njengomphathi) |
Amanothi:
- Izimbobo ze-PAD ziphromothwa ngokuzenzakalelayo ukuthi zibe phezulu kulo lonke uhlelo lokuklama.
- Izimbobo okungezona eze-PAD kufanele zithuthukiswe mathupha ziye ezingeni eliphezulu ukusuka kukhanvasi yokumisa ye-MSS ukuze itholakale njengezinga elilandelayo lesigaba.
I-Actel ingumholi kuma-FPGA anamandla aphansi kanye namasignali axubile futhi inikeza iphothifoliyo ebanzi kakhulu yohlelo nokuphathwa kwamandla. Izinto Zamandla. Funda kabanzi ku-5Hhttp://www.actel.com .
