Fetileview
PmodGYRO ke mochine oa peripheral o nang le STMicroelectronics® L3G4200D MEMS motion sensor. L3G4200D e fana ka gyroscope e hlahisoang ke dijithale ea likarolo tse tharo e nang le sensor ea mocheso.
Likarolo li kenyelletsa:
- SPI e tloaelehileng le I2C™ interface
- 250/500/2000dps Liqeto tse Khethang
- Lithakhisa tse peli tse sitisang
- Matla a tlase le Mokhoa oa ho Robala
- Tlhophiso ea mats'oao e ka lokisoang
Tlhaloso ea Ts'ebetso
PmodGYRO e sebelisa khokahanyo e tloaelehileng ea li-pin-12 'me e buisana ka SPI kapa I²C, e ikamahanya le puisano ea I²C. Sehanyetsi se hulang holimo moleng oa CS se boloka sesebelisoa se le maemong a I²C ntle le haeba mohala oa CS o tsamaisoa tlase ke sesebelisoa se hloahloa.
Sehokedi
Ha o buisana le sesebelisoa monghali o tlameha ho fana ka aterese ea ngoliso le folakha e hlalosang hore na ketso e latelang ke ho bala kapa ho ngola. Phetiso ea 'nete ea data e latela taelo ena. Ka mokhoa ona, mosebelisi a ka hlophisa sesebelisoa ka ho ngolla lirekoto tse itseng tsa taolo ka har'a sesebelisoa, kapa a bale lintlha tsa morao-rao ho tsoa ho lirekoto tse fapaneng tse baloang feela.
Litšitiso tse peli ka kotloloho ho 'mapa oa liphini tse fumanehang ho mosebelisi ho sehokelo J1 sa PmodGYRO. Tlhophiso ea INT1, e teng ho pin 7 ea J1, e ka khoneha ka ho feletseng. Tšebeliso ea mantlha ea INT1 e bakoa ke liketsahalo tse phahameng le tse tlase ho lilepe tse tharo tseo gyroscope e lekanyetsang lebelo la angular. Ka kamehla, INT1 e koetsoe. Khatiso ea bobeli, INT2, e sebelisoa haholo-holo bakeng sa data e lokisitsoeng le FIFO e sitisa le limmapa ho penya 8 ho J1.
Bakeng sa tlhaiso-leseling e batsi mabapi le lirejista tsa taolo, pokello ea data, le litlhophiso tse sitisang tse fumanehang bakeng sa tlhophiso ea basebelisi, bona leqephe la data bakeng sa L3G4200D ho STMicroelectronics®. websebaka.
Puisano ea SPI
Sebopeho sa SPI se sebelisa mela e meraro kapa e mene ea lipontšo bakeng sa puisano ho itšetlehile ka tlhophiso ea hona joale ea sesebelisoa. Tsena ke Chip Select (CS), Serial Data In (SDI) kapa feela Serial Data (SDA) ka 3-terata SPI mode, Serial Data Out (SDO), le Serial Clock (SCL). PmodGYRO e fetohela ho mokhoa oa ho sebetsa oa terata tse 4. E le hore u sebelise mokhoa oa 3-wire, rejisetara ea taolo e tlameha ho ngolloa. Bakeng sa puisano e felletseng ea SPI, sheba leqephe la data la sesebelisoa.
I²C Puisano
Tekanyetso ea I²C e sebelisa mela e 'meli ea matšoao, data ea I²C (SDA) le serial clock (SCL). Sesebelisoa se ts'ehetsa lioache tse tloaelehileng, 100 kHz, 'me ka potlako, 400 kHz, lioache tsa serial. Ho latela protocol ea I²C, L3G4200D e na le aterese e khethehileng ea 7-bit e sebelisoang ke serial master ho buisana le lisebelisoa tse ngata ka bese ea data. Sesebelisoa se sebelisa aterese ea 110100xb, moo pin 3 ho J1 (SDO/SA0) e hlalosang bonyane ba bohlokoa haholo (LSB). Ka ho sa feleng, LSB ea aterese ha e ntse e le '1' ka lebaka la sehanyetsi se hulelang holimo ho JP1 joalo ka ha ho bonts'itsoe ke moralo o fumanehang ho Digilent. websebaka. Le ha boleng ba kamehla e le '1', ka ho hokela pin 3 ho J1 ho seporo sa fatše mosebelisi a ka fetola LSB ho '0'. Karolo ena e ka khethoang ke mosebelisi e nolofalletsa li-PmodGYRO tse peli hore li sebelisoe beseng e le 'ngoe ea I²C. Leqephe la lintlha bakeng sa L3G4200D le na le lintlha tse ling tsa I²C tsa lisebelisoa.
