PmodGYRO jẹ module agbeegbe ti o nfihan sensọ išipopada STMicroelectronics® L3G4200D MEMS. L3G4200D n pese gyroscope oni-nọmba oni-nọmba oni-nọmba mẹta ti a ṣe sinu sensọ iwọn otutu.
Awọn ẹya pẹlu:
- Standard SPI ati I2C™ ni wiwo
- 250/500/2000dps Yan Awọn ipinnu
- Meji asefara da gbigbi awọn pinni
- Agbara-isalẹ ati Ipo oorun
- Sisẹ ifihan agbara atunto olumulo
Apejuwe iṣẹ-ṣiṣe
PmodGYRO naa nlo asopọ 12-pin boṣewa ati ibaraẹnisọrọ nipasẹ SPI tabi I²C, aifọwọyi si ibaraẹnisọrọ I²C. Atako ti o fa soke lori laini CS jẹ ki ẹrọ naa wa ni ipo I²C ayafi ti laini CS ba lọ silẹ nipasẹ ẹrọ titunto si
Ni wiwo
Nigbati o ba n ba ẹrọ sọrọ, oluwa gbọdọ pese adirẹsi iforukọsilẹ ati asia kan ti n ṣalaye boya igbese ti o tẹle jẹ kika tabi kikọ. Gbigbe gangan ti data tẹle aṣẹ yii. Nipasẹ ọna yii, olumulo le tunto ẹrọ naa nipa kikọ si awọn iforukọsilẹ iṣakoso kan pato laarin ẹrọ naa, tabi ka data pada lati awọn iforukọsilẹ kika lọtọ.
Awọn idilọwọ meji maapu taara si awọn pinni ti o wa fun olumulo lori asopo J1 ti PmodGYRO. Iṣeto ni INT1, ti o wa lori pin 7 ti J1, jẹ isọdi olumulo patapata. Lilo akọkọ ti INT1 jẹ lati awọn iṣẹlẹ giga ati kekere lori awọn aake mẹta nipa eyiti gyroscope ṣe iwọn iyara igun. Nipa aiyipada, INT1 jẹ alaabo. Idilọwọ keji, INT2, jẹ lilo akọkọ fun imurasilẹ data ati awọn idilọwọ FIFO ati awọn maapu lati pin 8 lori J1.
Fun alaye diẹ sii nipa awọn iforukọsilẹ iṣakoso, ikojọpọ data, ati awọn eto idalọwọduro ti o wa fun iṣeto olumulo, wo iwe data fun L3G4200D lori STMicroelectronics® webojula.
SPI Ibaraẹnisọrọ
Ni wiwo SPI nlo awọn laini ifihan agbara mẹta tabi mẹrin fun ibaraẹnisọrọ da lori iṣeto lọwọlọwọ ti ẹrọ naa. Iwọnyi jẹ Chip Select (CS), Data Serial Ni (SDI) tabi nirọrun Serial Data (SDA) ni ipo SPI-waya 3, Data Serial Out (SDO), ati Aago Serial (SCL). PmodGYRO ṣe aipe si ipo iṣẹ waya 4. Lati le lo ipo waya 3, iforukọsilẹ iṣakoso gbọdọ wa ni kikọ si. Fun alaye diẹ sii ibaraẹnisọrọ SPI, tọka si iwe data ẹrọ naa.
I²C Ibaraẹnisọrọ
Iwọn I²C nlo awọn laini ifihan agbara meji, data I²C (SDA) ati aago ni tẹlentẹle (SCL). Ẹrọ naa ṣe atilẹyin boṣewa mejeeji, 100 kHz, ati iyara, 400 kHz, awọn aago ni tẹlentẹle. Ni ibamu pẹlu ilana I²C, L3G4200D ni awọn ohun elo kan pato adirẹsi 7-bit ti oluwa ni tẹlentẹle nlo lati ṣe ibasọrọ pẹlu awọn ẹrọ lọpọlọpọ lori ọkọ akero data kan. Ẹrọ naa nlo adiresi 110100xb, nibiti pin 3 lori J1 (SDO/SA0) ṣe alaye ti o kere julọ-bit (LSB). Nipa aiyipada, LSB ti adirẹsi nigba ti o jẹ '1' nitori atako-fa soke lori JP1 bi o ṣe han nipasẹ sikematiki ti o wa lori Digilent webojula. Lakoko ti iye aiyipada jẹ '1', nipa sisọ pin 3 nirọrun lori J1 si iṣinipopada ilẹ olumulo le yi LSB pada si '0' kan. Oṣere yiyan olumulo yii jẹ ki awọn PmodGYRO meji le ṣee lo lori ọkọ akero I²C kanna. Iwe data fun L3G4200D ni alaye I²C kan pato ẹrọ siwaju sii.
