Chitsauko 1: Nhanganyaya

Iyi serial communication board yakagadzirirwa kushandiswa muPC/104 makomputa anoenderana. Maviri akasarudzika serial data ports anopiwa pabhodhi. Model COM-2S ingori isiri yega yega yeICOM-2S.

Multipoint Opto-isolated Communications
Bhodhi rinobvumira kutapurirana mapoinzi akawanda pamitsara yekutaurirana yakareba munzvimbo dzine ruzha uchishandisa RS422 kana RS485 madhiraivha ekusiyanisa mitsetse. Mitsara yedata ndeye opto-yakasarudzika kubva pakombuta uye kubva kune mumwe kune imwe kuvimbisa kutaurirana kana hombe yemodhiyo ruzha rwakasimudzwa. Iwo ari pabhodhi DC-DC anoshandura anopa ega simba kune mutsara wemutyairi maseketi.

A crystal oscillator iri pabhodhi. Iyi oscillator inobvumira kusarudzwa chaiko kwemabaud mitengo kubva pa50 kusvika 115,200. Baud mitengo inosvika 460,800 baud inogona kupihwa senge fekitori sarudzo. Chikamu cheProgramming chebhuku rino chine tafura yekushandisa pakusarudza chiyero chebhaud.
Matransceivers ekubuda anoshandiswa, mhando 75176B, anokwanisa kutyaira mitsara yekutaurirana yakareba zvakanyanya pamitengo yakakwira baud. Vanogona kutyaira kusvika ku ± 60mA pamitsetse yakadzikama uye vanogashira zvinopinda zvakaderera se ± 200mV chiratidzo chekusiyanisa. Opto-isolators pabhodhi inopa dziviriro kusvika ku500 V. Muchiitiko chekukakavadzana kwekukurukurirana, ma transceivers anoratidza kuvhara kwekushisa.

COM Port kuenderana
Type ST16C550 UARTs inoshandiswa seAsynchronous Communication Element (ACE) iyo inosanganisira 16-byte transmit/receive buffer kudzivirira kubva kurasika data mumamultitasking masisitimu anoshanda, uku uchichengeta zana muzana kuenderana neyekutanga IBM serial port.
Iwe unogona kusarudza kero yekutanga chero mukati meI/O kero renji 000 kusvika 3E0 hex.
Kukurukurirana Modes
Iyi modhi inotsigira akasiyana 2-waya uye 4-waya tambo dzekubatanidza. 2 waya kana Hafu-Duplex inobvumira traffic kufamba munzira mbiri, asi nzira imwe chete panguva. Mune 4 waya kana Yakazara-Duplex modhi data inofamba mumativi ese panguva imwe chete.

Mutsara Kurerekera uye Kugumisa
Kuti uwedzere kudzivirira kweruzha, mitsara yekutaurirana inogona kutakurwa kune inogamuchira uye yakarerekera kune inotumira. RS485 kutaurirana inoda kuti imwe transmitter ipe bias voltage kuona iyo inozivikanwa "zero" mamiriro kana ese ma transmitter adzimwa, uye yekupedzisira inogashira kumagumo etiweki inomiswa kudzivirira "kurira". Bhodhi rinotsigira sarudzo idzi nemajumper pabhodhi. Ona Chitsauko 3, Sarudzo yeSarudzo kuti uwane rumwe ruzivo.

Transceiver Control
Kukurukurirana kweRS485 kunoda kuti mutyairi wetransmitter agoneswe uye aregedzwe sezvinodiwa, kubvumidza mabhodhi ese kugovera tambo yekutaurirana. Bhodhi rine automatic driver control. Kana bhodhi risiri kufambisa, inogamuchira inogoneswa uye mutyairi wetransmitter akaremara. Pasi pekutonga otomatiki, kana data ichizoendeswa, mugamuchiri akaremara uye mutyairi anogoneswa. Bhodhi rinogadzirisa nguva yaro kune baud rate ye data.

Yechipiri yekutanga nhanho ndeye kuseta iyo Line Control Register paBase Kero +3. Iri rejisita rinotsanangura kureba kwezwi, kumisa bits, parity, uye iyo DLAB.

Bits 0 uye 1 kudzora urefu hwezwi uye bvumira kureba kwemazwi kubva pa5 kusvika ku8 bits. Bit marongero anotorwa nekubvisa 5 kubva pahurefu hwezwi hunodiwa.
Bit 2 inosarudza nhamba yekumira bits. Panogona kunge paine imwe kana maviri ekumira mabits. Kana Bit 2 ikaiswa ku0, pachave nekumira zvishoma. Kana Bit 2 ikaiswa ku1, pachave nembiri dzekumira.
Bits 3 kuburikidza ne6 kudzora parity uye kuputsa kugonesa. Iwo haawanzo shandiswa pakutaurirana uye anofanirwa kuiswa kune zeroes.

Nhanho yechitatu yekutanga kutevedzana ndeye kuseta iyo Modem Kudzora Rejista paBase Kero +4. Rejista iyi inodzora mabasa pane mamwe mabhodhi. Bit 1 ndiyo Chikumbiro Chekutumira (RTS) control bit. Iyi bhiti inofanira kusiiwa yakaderera kusvika nguva yekufambisa. (Cherechedza: Paunenge uchishanda mune otomatiki RS485 modhi, mamiriro eichi bhiti haana kukosha.) Bits 2 uye 3 ndeye-yakatarwa nevashandi. Bit 2 inogona kufuratirwa pabhodhi iri. Bit 3 inoshandiswa kugonesa kuvhiringidza uye inofanirwa kuiswa pakakwirira kana inofambiswa-inofambiswa inogamuchira ichizoshandiswa. Yekupedzisira yekutanga nhanho ndeyekutsvaira mabhafa ekugamuchira. Iwe unoita izvi nekuverenga kuviri kubva kune inogamuchira buffer paBase Kero +0. Kana yaitwa, iyo UART yakagadzirira kushandisa.

Reception
Kugamuchira kunogona kubatwa nenzira mbiri: kuvhota uye kukanganisa-inofambiswa. Pakuvhota, kugamuchira kunoitwa nekugara uchiverenga Line Status Rejista paBase Kero +5. Bit 0 yeiyi rejista inoiswa kumusoro pese kana data yagadzirira kuverengerwa kubva kuchip. Kuvhota hakushande pamitengo yepamusoro yedata iri pamusoro nekuti chirongwa hachigone kuita chero chimwe chinhu kana chiri kuvhota kana data rinogona kupotsa. Iyo inotevera kodhi chidimbu inoshandisa polling loop uye inoshandisa kukosha kwe13, (ASCII ngoro yekudzoka) seyekupedzisira-yekutumira-mucherechedzo:
