PmodCMPS yana amfani da HMC5883L na Honeywell tare da fasahar Anisotropic Magnetoresitive (AMR). A cikin Ingilishi a sarari, wannan yana nufin cewa na'urori masu auna firikwensin guda uku (ɗaya ga kowane jagorar daidaitawa) suna da ɗan tsangwama ga juna don a iya dawo da ingantattun bayanai daga Pmod.

Yin hulɗa tare da Pmod

Pmod CMPS yana sadarwa tare da hukumar gudanarwa ta hanyar ka'idar I²C. Jumpers JP1 da JP2 suna ba da resistors 2.2kΩ na zaɓi don amfani da Serial Data da Serial Clock Lines. Adireshin 7-bit na wannan guntu akan allo shine 0x1E, yana yin adireshin 8-bit don umarnin karantawa 0x3D da 0x3C don umarnin rubutu.

Ta hanyar tsoho, PmodCMPS yana farawa a cikin Yanayin Auna Guda ta yadda kamfas ɗin ya ɗauki ma'auni guda ɗaya, ya saita babban fil ɗin Shiryewar Bayanai, sannan ya sanya kansa cikin Yanayin Ragewa. Yayin da yake cikin Yanayin Ragewa, manyan hanyoyin amfani da wutar lantarki (ba abin mamaki bane) nakasassu, kamar ADC na ciki wanda ke tattara vol.tage ma'auni. Koyaya, har yanzu kuna iya samun damar duk rajistar tare da ƙimar bayanan kwanan nan ta cikin bas ɗin I²C. Don canza PmodCMPS daga yanayin mara amfani baya zuwa ma'auni guda ɗaya ko yanayin auna ci gaba, mai amfani dole ne ya rubuta zuwa Rijistar Yanayin (0x02).
