Enwere nhọrọ abụọ dị maka K66F kpọmkwem PDM nkwurịta okwu nke chọrọ mgbakwunye software protocol na CPU cycles iji jikwaa protocol PDM ma ọ bụ jiri DA7212 iji tọghata PDM na ofufe na Pulse-code modulation (PCM) maka nkwukọrịta K66F. Site na ndabara, J30 na J31 bụ shunt 1-2 gaa DA7212.

Njikọ I/O

Igwe isi
Enwere ike itinye isi ekweisi ọkọlọtọ nwere igwe okwu na FRDM-K66F site na oghere 3.5 mm 4-pole J28. Enwere nhazi abụọ na ekweisi dabere na onye nrụpụta isi. Enwere ike iji J35 1-2 na J36 1-2 (Ntọala ndabara) ma ọ bụ J35 2-3 na J36 2-3 na-ebugharị akara MIC na GND maka nhazi abụọ ahụ. Igwe ekweisi aka ekpe na aka nri ka edobere.

Mkpebi DC maka igwe okwu isi sitere na MICBIAS2. Ihe mgbama igwe bụ ntinye na DA7212 na MIC2_R.

Enwere ike ijikọ akara ngosi analog na ntinye inyeaka AUX_L/AUX_R site na oghere jakị 3.5 mm J29. Ntinye analọg ahụ bụ nke DC na-enweghị isi ma tinye usoro DC igbochi capacitor n'ụzọ ntinye.

Igwe okwu analog
Enwere ike itinye igwe okwu analog abụọ dị na bọọdụ site na nkụnye eji isi mee 1 × 2 J32 na J33. A na-ebugharị J32 pin 1 na MIC1_R na J33 pin 1 ga-ebuga na MIC2_R. Ma J32 na J33 pin 2 bụ ala. MIC2_R ejikọrọ na 3.5 mm igwe isi okwu abụọ J28. MICBIAS1 na-enweta nhụsianya DC maka MIC1_R na MIC2_R sitere na MICBIAS2.
