DIGILENT PmodGYRO 3-Axis Gyroscope

Tlhahisoleseding ya Sehlahiswa

PmodGYRO ke gyroscope ea 3-axis e tsamaisoang ke STMicroelectronics L3G4200D. E etselitsoe ho fana ka lintlha tsa ho utloa ho sisinyeha ho e 'ngoe le e 'ngoe ea lilepe tse tharo tsa Cartesian. Mojule o ka hlophisoa ho tlaleha lebelo la angular ka qeto ea ho fihla ho 2000 dps (likhato ka motsotsoana) ka sekhahla sa tlhahiso ea ho fihla ho 800Hz. E na le gyroscope ea dijithale ea 3-axis MEMS e nang le ts'ebetso e phahameng ea ts'oenyeho le tharollo e ka khethoang ke mosebelisi (250/500/2000dps).

Litaelo tsa Tšebeliso ea Sehlahisoa

Ho hokahana le PmodGYRO, o ka sebelisa liprothokholo tsa puisano tsa SPI kapa I2C. Mojule o buisana le chip ea gyroscope ea ST L3G4200D ho fumana lintlha tsa ho utloa ho sisinyeha.

Ho kopana le Pmod

PmodGYRO e na le lihlooho tse peli, J1 le J2, tse fanang ka pinout bakeng sa ho hokahanya. Tafole ea tlhaloso ea pinout e tjena:

Hlokomela: Matla leha e le afe a ka ntle a sebelisoang ho PmodGYRO a tlameha ho ba ka har'a 2.4V le 3.6V, le hoja ho kgothaletswa ho sebetsa Pmod ho 3.3V.

Khutlisa Lintlha

Lintlha tse lekantsoeng tse tsoang ho gyroscope li ngotsoe le ho bolokoa lirejiseteng tsa L3G4200D ka likhato ka motsotsoana (dps). Boleng bo lekantsoeng ba 360 dps bo lekana le 60 rpm. U ka fumana lintlha ho tsoa ho PmodGYRO ka ho latela khoutu e fanoeng example bukeng ea mosebelisi.

Fetileview

PmodGYRO ke gyroscope ea 3-axis e tsamaisoang ke STMicroelectronics L3G4200D. Ka ho buisana le chip ka SPI kapa I2C, basebelisi ba ka hlophisa module ho tlaleha lebelo la angular ka qeto ea ho fihla ho 2000 dps ka sekhahla sa tlhahiso ho fihla ho 800Hz.

Likarolo li kenyelletsa:

• 3-axis MEMS digital gyroscope e nang le pholoho e phahameng ea ts'oenyeho
• Fumana lintlha tsa lebelo la angular ka tharollo e ka khethoang ke mosebelisi (250/500/2000dps)
• Lithakhisa tse peli tse sitisang

• 12-pin Pmod port e nang le sebopeho sa SPI le I²C e eketsehileng
• Laebrari le mohlalaample khoutu e fumaneha setsing sa lisebelisoa

Tlhaloso ea Ts'ebetso

PmodGYRO e sebelisa gyroscope ea ST L3G4200D ho fana ka lintlha tsa ho lemoha ho sisinyeha ho e 'ngoe le e 'ngoe ea lilepe tse tharo tsa Cartesian. Basebelisi ba ka hlophisa likhetho le likhetho tsa ho sefa bakeng sa data e lekantsoeng.

Ho kopana le Pmod

PmodGYRO e buisana le boto e amohelang batho ka liprothokholo tsa SPI kapa I²C. Ka ho khanna mohala oa Chip Select (CS) ho ea ho logic low voltage state, SPI mode e butswe.
