Bhodhi racho rine bhatani reReset (2), iro riri kuseri kwebhodhi. Inoshandiswa kugadzira LOW logic level pane microcontroller reset pini.

Power supply unit

Iyo magetsi emagetsi unit (PSU) inopa yakachena uye yakadzorwa simba, inodiwa pakushanda kwakakodzera kweiyo mikromedia 5 FPI yekuvandudza bhodhi. Iyo inotambira MCU, pamwe chete nemamwe maperipherals, inoda kudzorwa uye isina ruzha magetsi ekupa. Naizvozvo, iyo PSU yakanyatso kugadzirirwa kudzora, kusefa, uye kugovera simba kune ese zvikamu zve mikromedia 5 FPI. Iyo yakashongedzerwa neatatu akasiyana emagetsi emagetsi ekuisa, achipa ese anochinjika ayo mikromedia 5 FPI inoda, kunyanya kana ichishandiswa pamunda kana sechinhu chakabatanidzwa chehurongwa hombe. Mune iyo nyaya kana akawanda masosi emagetsi achishandiswa, otomatiki magetsi ekuchinja dunhu ane zvakafanotsanangurwa zvinoona kuti yakanyanya kukodzera ichashandiswa.

Iyo PSU zvakare ine yakavimbika uye yakachengeteka bhatiri yekuchaja dunhu, iyo inobvumira imwe-sero Li-Po/Li-Ion bhatiri kuchajwa. Simba OR-ing sarudzo inotsigirwawo, ichipa isina kukanganiswa magetsi ekupa (UPS) kushanda kana kunze kana USB sosi yemagetsi inoshandiswa pamwe chete nebhatiri.

Tsanangudzo yakadzama

Iyo PSU ine basa rinoda kwazvo rekupa simba kune iyo inotambira MCU uye ese maperipherals ari mubhodhi, pamwe neaya akabatana nekunze. Chimwe chezvakakosha zvinodikanwa kupa zvakakwana ikozvino, kudzivirira voltage donhedza pane zvabuda. Zvakare, iyo PSU inofanirwa kukwanisa kutsigira akawanda magetsi masosi ane akasiyana mazita voltages, kubvumira kuchinja pakati pavo nekutanga. Iyo PSU dhizaini, yakavakirwa pane seti yepamusoro-inoshanda simba switching ICs inogadzirwa neMicrochip, inova nechokwadi chemhando yakanaka yekubuda vol.tage, yakakwira ikozvino mwero, uye yakaderedzwa yemagetsi mwaranzi.

Pakupinza stage yePSU, iyo MIC2253, yakakwirira-inoshanda inosimudzira regulator IC ine overvolvetage protection inovimbisa kuti voltage input pane inotevera stage inodzorwa zvakanaka uye yakagadzikana. Inoshandiswa kuwedzera voltage ye low-voltage magetsi masosi (a Li-Po/Li-Ion bhatiri uye USB), ichibvumira inotevera stage kuendesa yakanyatsogadziriswa 3.3V uye 5V kubhodhi rekuvandudza. Seti yezvikamu zvakasiyana-siyana zvinoshandiswa kuona kana simba rekupinza rinoda voltage boost. Kana akawanda masosi emagetsi akabatana kamwechete, iyi siketi inoshandiswawo kuona iyo yekuisa yekutanga nhanho: kunze yakabatana 12V PSU, simba pamusoro pe USB, uye Li-Po/Li-Ion bhatiri.

Shanduko pakati pemasimba anowanikwa emagetsi akagadzirirwa kupa kusakanganiswa kushanda kwebhodhi rekuvandudza. Iyo inotevera PSU stage inoshandisa maviri MIC28511, synchronous stepdown (buck) regulators, inokwanisa kupa kusvika ku3A. Iyo MIC28511 IC inoshandisa HyperSpeed ​​Control® uye HyperLight Load® zvivakwa, ichipa mhinduro yekukurumidza-inokurumidza kupfupika uye yakakwirira-yekuremedza mwenje kunyatsoshanda. Imwe neimwe yeaviri mabheji ekudzora anoshandiswa kupa simba kune inoenderana magetsi emagetsi njanji (3.3V uye 5V), mukati mese bhodhi rekusimudzira uye akabatana maperipheral.

Voltage reference

Iyo MCP1501, yakakwira-chaiyo buffered voltage referensi kubva kuMicrochip inoshandiswa kupa iro rakanyatsojeka voltage referensi isina voltage drift. Inogona kushandiswa kune zvakasiyana siyana: iyo inonyanya kushandiswa inosanganisira voltage mareferensi eA/D anoshandura, D/A anoshandura, uye anoenzanisa peripherals pane iyo host MCU. Iyo MCP1501 inogona kupa kusvika ku20mA, ichimisa kushandiswa kwayo chete kune vol.tage comparator application ine yakakwira yekupinza impedance. Zvichienderana nechishandiso chaicho, ingave 3.3V kubva panjanji yemagetsi, kana 2.048V kubva kuMCP1501 inogona kusarudzwa. Iyo iri paboard SMD jumper yakanyorwa kuti REF SEL inopa maviri voltage referensi sarudzo:

Midziyo inoenderana neruzha

Nekupa maviri ezviyo zvine chekuita neruzha, mikromedia 5 FPI inotenderedza-up iyo multimedia pfungwa. Iyo ine piezo-buzzer, iri nyore kwazvo kuronga asi inogona kuburitsa chete manzwi akareruka, anobatsira chete kumaalarm kana zviziviso. Yechipiri yekuteerera sarudzo ndiyo ine simba VS1053B IC (1). Iyo Ogg Vorbis/MP3/AAC/WMA/FLAC/WAV/MIDI odhikodha decoder, uye PCM/IMA ADPCM/Ogg Vorbis encoder, ese ari pane imwechete chip. Iyo inoratidzira ine simba DSP musimboti, yepamusoro-mhando A/D uye D/A inoshandura, stereo mahedhifoni mutyairi anokwanisa kutyaira 30Ω mutoro, zerocross yekuona ine yakatsetseka vhoriyamu shanduko, bass uye treble control, uye zvimwe zvakawanda.

Piezo buzzer
Piezo buzzer (2) mudziyo uri nyore unokwanisa kuburitsa ruzha. Inotungamirirwa nediki pre-biased transistor. Iyo buzzer inogona kufambiswa nekushandisa chiratidzo chePWM kubva kuMCU pazasi pe transistor: kurira kweinzwi kunoenderana nekuwanda kweiyo PWM chiratidzo, nepo vhoriyamu inogona kudzorwa nekuchinja basa rayo kutenderera. Sezvo zviri nyore kwazvo kuronga, zvinogona kubatsira zvakanyanya kune akareruka maaramu, zviziviso, uye mamwe marudzi ezvakareruka masaini masaini.

Audio CODEC

Resource-inoda uye yakaoma maodhiyo ekugadzirisa mabasa anogona kuburitswa kubva kune iyo host MCU nekushandisa yakatsaurirwa odhiyo CODEC IC, yakanyorwa seVS1053B (1). Iyi IC inotsigira akawanda akasiyana maodhiyo mafomati, anowanzo kuwanikwa pane akasiyana siyana edhijitari madhijitari. Iyo inogona encode uye decode odhiyo hova yakazvimiririra ichiita DSP-ane hukama mabasa akafanana. Iyo VS1053B ine akati wandei akakosha maficha anoita iyi IC yakakurumbira sarudzo kana zvasvika pakugadzirisa odhiyo.

Nekupa yemhando yepamusoro hardware compression (encoding), iyo VS1053B inobvumira iyo odhiyo kurekodhwa ichitora nzvimbo shoma kana ichienzaniswa neiyo yakafanana ruzivo rweodhiyo mune yayo mbishi fomati. Mukubatana nepamusoro-mhando ADCs uye maDACs, mutyairi wemahedhifoni, yakasanganiswa odhiyo yakaenzana, kutonga kwevhoriyamu, uye nezvimwe, inomiririra mhinduro-yakatenderedza chero mhando yeaudio application. Pamwe chete neiyo ine simba giraidhi processor, iyo VS1053B yekuteerera processor inotenderedza zvizere-pamusoro mamultimedia emikromedia 5 FPI yekuvandudza bhodhi. Iyo mikromedia 5 FPI board ine 3.5mm ina-pole mahedhifoni jack (3), inobvumira kubatanidza mahedhifoni nemakrofoni.

Sensors uye mamwe maperipherals

Seti yemamwe maonboard sensors nemidziyo inowedzera imwezve dhizaini yekushandisa kune iyo mikromedia 5 FPI yekuvandudza bhodhi.

Digital motion sensor
Iyo FXOS8700CQ, yepamberi yakasanganiswa 3-axis accelerometer uye 3-axis magnetometer, inokwanisa kuona zvakawanda zvakasiyana-siyana zvine chekuita nekufamba, zvinosanganisira kutariswa kwechiitiko chekutarisa, kuona kusununguka, kuona kuvhunduka, pamwe nekutep, uye kupeta kaviri chiitiko chiitiko. Zviitiko izvi zvinogona kutaurwa kune iyo inotambira MCU pamusoro pemapini maviri akazvitsaurira ekukanganisa, nepo kuendesa data kunoitwa pamusoro peiyo I2C yekutaurirana interface. Iyo FXOS8700CQ sensor inogona kubatsira zvakanyanya pakuonekwa kwekutarisa. Inogona zvakare kushandiswa kushandura mikromedia 5 FPI kuita yakakwana 6-axis e-compass mhinduro. Iyo I2C kero yemuranda inogona kuchinjwa nekushandisa maviri SMD jumpers akaiswa pasi peiyo ADDR SEL label (1).

Yechokwadi-nguva wachi (RTC)

Iyo inotambira MCU ine chaiyo-nguva wachi peripheral module (RTC). Iyo RTC peripheral inoshandisa yakaparadzana magetsi sosi, kazhinji bhatiri. Kubvumira kuenderera mberi kwekutevera nguva, mikromedia 5 FPI ine bhatani cell bhatiri inochengetedza RTC kushanda kunyangwe iyo huru magetsi AKADZIMWA. Kunyanya kuderera kwesimba rekushandisa kweRTC peripheral inobvumira mabhatiri aya kuti agare kwenguva refu. Iyo mikromedia 5 FPI yekuvandudza bhodhi ine bhatani cell bhatiri inobata (2), inoenderana neSR60, LR60, 364 bhatani bhatiri marudzi ebhatiri, ichiibvumira kuti ibatanidze wachi chaiyo yenguva mukati mezvishandiso.
