PmodMIC3 bụ igwe okwu MEMS nke Knowles Acoustics SPA2410LR5H-B na Texas Instruments ADCS7476 kwadoro. Ndị ọrụ nwere ike iji obere potentiometer gbanwee olu na-abata na bọọdụ sistemu tupu ha anata ibe 12 nke data site na SPI. PmodMIC3.
Atụmatụ gụnyere:
- MEMS Microphone modul nwere interface dijitalụ
- Jiri ntụgharị 12-bit A/D gbanwee ntinye ọdịyo
- Gbanwee olu mbata na potentiometer nọ n'ụgbọ
Nkọwa ọrụ
Emebere PmodMIC3 ka ọ na-akọ akụkọ dijitalụ na bọọdụ nnabata mgbe ọ bụla ọ chọpụtara mkpọtụ mpụga ọ bụla. Site na izipu onye nnọchi anya uru dijitalụ 12-bit nke ugboro na olu nke mkpọtụ, ọnụ ọgụgụ a nwere ike ịhazi ya site na bọọdụ sistemụ wee nwetaghachi ụda nnata nke ọma site na ọkà okwu. Enwere ike iji potentiometer nke nọ n'ụgbọ iji gbanwee uru sitere na igwe okwu banye ADC.
