DIGILENT PmodGYRO 3-axis gyroscope
Ozi ngwaahịa
PmodGYRO bụ gyroscope 3-axis kwadoro site na STMicroelectronics L3G4200D. Emebere ya iji nye data mmetụta ngagharị na nke ọ bụla n'ime anyụike atọ Cartesian. Enwere ike ịhazi modul ahụ ka ọ kọọ ọkụ ọkụ n'akụkụ na mkpebi ruru 2000 dps (ogo kwa nkeji) na ọnụego mmepụta ruru 800Hz. Ọ nwere gyroscope dijitalụ 3-axis MEMS nwere nnukwu nlanarị ujo yana mkpebi onye ọrụ nwere ike họrọ (250/500/2000dps).
Ntuziaka ojiji ngwaahịa
Iji jikọọ na PmodGYRO, ịnwere ike iji usoro nkwukọrịta SPI ma ọ bụ I2C. Modul ahụ na-ekwurịta okwu na mgbawa gyroscope ST L3G4200D iji weghachite data mmetụta ngagharị.
