Chii ru-pachiteshi? The mudziyo, ru-chengarava utariri

Ru-Chiteshi, kana Serial chengarava riri bidirectional Serial inowanikwa iri rakagadzirirwa byte date exchange. Kokutanga, chiteshi chengarava rinoshandiswa batanidza chirwere uye zvadaro Modem, uye mbeva. Zvino inowanzoshandiswa kubatanidza uninterruptible simba nerubatsiro uye kuti kukurukura Hardware kubudiswa kadambari hurongwa midzi mhando.

kushandiswa

Saka, usati kutaura zvakawanda pamusoro kuti ru-pachiteshi, unofanira kuongorora zvekare kunzwisisa zvarinoreva. Makore 15 apfuura, nzira inoshandiswa kubatanidza mano kuti kombiyuta Via chaiwo mwero connector iri seri chassis uchishandisa unokosha Serial RS-232 waya. Nzira iyi ine payakaipira zhinji. waya akadaro, nezvinodiwa ano, inopa pasi kwazvo date zvazvingava - vanenge zana kilobits por wechipiri. Uyezve, kana achiita kubatana pakati connectors vaifanira kushandisa shutdown ari midziyo mumuviri, uye dzakanga dzakabatanidzwa mumwe achishandisa screws, kuitira kuvimbika, apo saizi kwavo kunobva wandei ukoshi.

A Nhoroondo shoma

Ru-chiteshi chengarava raiva ipapo makombiyuta dzinozivikanwa vaipfeka nhamba 1 kana 2, sezvo ivo vari kazhinji hapana anopfuura maviri. Unogona kuisa mamwe zvengarava kana vachimuka kudiwa. Kana mushandisi Software setup kunodiwa kuti vadzivise kuvhiringidzika uye zvakarurama urigadze ndiye unobatanidza anodikamwa zvokushandisa. Mumwe ru-chiteshi Kurongwa zvinoda nhamba kwakarurama pamusoro date yedzimudzangara, uyewo zvimwe cryptic parameters izvo aizivikanwa chete rakamanikana pedenderedzwa unyanzvi. Kubatanidza midziyo kuti abudirire, zvose parameters anodiwa aida nzvimbo kudzidza kana kunhonga experimentally, sezvo iyi, pakanga pasina chinhu otomatiki configuration. Uyezve, kubatana vachishandisa ru-chengarava inokwanisa unobatanidza chero Software chero midziyo zvokunze, kunyange chaizvo dzisingapindirani, ndokusaka ari mubishi yokumisa uye pane yakawanda zvikanganiso.

modernity

Zvino maererano Via ru-pachiteshi kwaidarika dzakawanda nzira ano, izvo zvinoda pasina ruzivo unokosha Implementation, kureva kuburikidza USB-chiteshi zvachose. Nzira iyi ndiyo isina ose zvainovhiringidzawo ambotaurwa. Zvisinei, ano mitemo kugarisana kubatana yamarudzi ose GPS-michina uye zvikuru heterogeneous Software aumba kwenguva refu kunhivi yokuti ru-zvengarava kuti takatora kuitika zvekare.

Izvi zvinosanganisira kuziva kuti pakutanga chero midziyo, kusanganisira GPS, aiva panze, uye kubatana kwayo kuti kombiyuta kuteererwa Serial waya chokuita mumwe Hardware zvengarava. Kubva mushandisi ari configuration kwacho kunodiwa kusarudza zvakarurama chiteshi nhamba uye mashoko rokushandura nokukurumidza pamusoro payo. Panguva iyoyo, paiva chikuru umbowo mureza kubva GPS-mugamuchiri purogiramu, zvino kunzi NMEA-0183. Kutaura zvazviri, mureza uyu zvinoda Developers zvose, kunyange Hardware ano uye Software kutaura kubudikidza ru-pachiteshi. Uye zvose izvi pamberi chii makombiyuta ano, uyewo CPC, vagara kunyanya ari USB mureza. Uye chimwe chinhu kuti ichangobva GPS-vagamuchiri vari kuramba akatanga iiswe zvakananga mukati yakakomberedzwa chiri chose vasipo chipi kubatana wire pakati payo uye huru mudziyo.

Virtual ru zviteshi

Nzira yokubuda yagadzirwa zvinoti kutanga "rakapotsa» ru-zvengarava. Zvakaratidza kuti dzomunyika Handheld mudziyo Somuenzaniso, GPS-mugamuchiri iri simulated mu-software sezvo ru-pachiteshi, nepo avo vasiri ari Hardware mazwi. In chirongwa ichi, icho rakagadzirirwa interfacing kuburikidza yakafanana mwero, hapana musiyano nayo sei rakatangwa. Panogona kuva pamberi rakapotsa simulation, uye kwete kuvapo Hardware Implementation. Saka zvinoita kuti tibu- kugarisana yekare womuenzaniso GPS-Software pamwe midziyo ano.

kuchinja

Panguva iyoyowo tichigadzirisa iyo ru-pachiteshi haana kuchinja yekudyidzana. The Old mushandisi anofanira kuita kunzwisisa setup anenge manually. Zvisinei, ano ru-chiteshi rinomirira kwete kura mudziyo anoiswa pamusoro rwemberi eDare hurongwa Unit, uye yakasiyana zvachose mudziyo. Zvino zvose ndechokuti kubva Software nemaonero, vose sokuti rekuremekedza pakuona, kureva, hapana musiyano pakati chaivoivo zvengarava. For-software chiteshi nhamba akasiyana chete kuti vari basa kuti PDA vagadziri kuti zvachose chero hwaro. Somuenzaniso, mugamuchiri mumwe ASUS makhiriniki pamusoro COM5, uye PocketLOOX 560 anoratidza mugamuchiri nokuda COM8. Zvakaratidza kuti purogiramu anoda kugamuchira kubva GPS-mugamuchiri Data rine pakutanga hapana mashoko akavimbika pamusoro kuzivikanwa nhamba pasi iyo pachiteshi sokuti, vave vakanyorwa kuti runoenzanirana mugamuchiri pamusoro PDA ichi.

zvose izvi basa sei?

With kuti, unogona kuita otomatiki kutsvaka yakakodzera muitiro ongororo zvose anowanika ru-zvengarava akadaro zvakarurama wokusavimbika uye zvikuru yainetsa. Izvi imhaka yokuti mudziyo akaratidza munyika sechipiriso ru-pachiteshi, inogona kunyatsonanga yakasiyanasiyana uye irege ukama GPS, vanogona kuva zvikuru nezvimwewo kupindura ongororo iyi. Somuenzaniso, PDA ndivo zvengarava chokuita dzomunyika cellular Modem, pamwe USB, michini chiteshi, uyewo mamwe zvinhu. Vasadaro chirongwa yakagadzirirwa kushanda chairo zano, kungaita kuti zvachose nezvimwewo siyana, uyewo malfunctions siyana kuti kunowanzokonzera ichimuremera PDA. Ndokusaka vachiedza kuvhura ru-pachiteshi kungaita kuti chisingatarisirwi ezvinhu kuti batidza Makaralı kana michini chiteshi. Uye pangava zvakawanda rakasviba zviitiko.

Jobs ru-chengarava

Nokuti ru-pachiteshi rinoshandiswa sepokutangira ane asynchronous yezvisikwa transceiver chip. Chip ichi inowanikwa siyana akawanda: Intel 16550A, 16550, 16450, 8250. Nokuti mumwe ru-pachiteshi nayo unotora munhu mugamuchiri evoruzhinji uye date wokutepfenyurisa uye nhamba rokudzora evoruzhinji kuti anogona kuwanikwa kuburikidza Bios, Windows uye MS dos. In matsva shanduro Chip akaronga kuti buffers kuti kwekanguva kuchengeta mashoko ari kutapukira uye akagamuchira. With kugona ichi, unogona kudimburira kushanda CPU zvishoma kakawanda, uyewo kuti batanidza umboo mwero nhepfenyuro.

Huru parameters

Ru-chiteshi mudziyo anotora kuvapo vakadaro mamirire zvinhu:

- garo Kero chengarava kuti inputting uye outputting ruzivo;

- the Hardware kudimburira nhamba;

- kukura imwe block mashoko;

- mwero panguva iyo mashoko ari zvitange;

- kuvimbika kuonekwa muoti;

- kuyerera kudzora nzira;

- Nhamba chemabhazi matomu.

How kutarisa ru-chiteshi chengarava riri kombiyuta yako? Chii kunotsvaka?

Sezvambotaurwa, kwakadai chengarava riri bi achitaura inowanikwa kuti umbowo Kupfuudzwa panguva vachitova pamwero nenzira yakarongeka nzira. The nevamwe Pakanzi tichienzanisa yakafanana chiteshi pano ndiyo ikakuruma Data kuchinjirwa kubudikidza wedzeredzei. Ru-Port anatomi akadaro kuti kombiyuta haazati oga anoshandisa Serial date hutachiwana nzira. Somuenzaniso, interfaces zvakadai Ethernet kana USB, kushandisawo ichocho, asi izvozvo ndizvo zvakaitika kare kuti Serial akaritumidza mureza RS232 pachiteshi.

Chinowanzoonekwa kunodiwa kuvhura ru-chengarava kuti kugadzira uye kombiyuta Diagnostics, apo zvakakodzerawo kunotarisa mutambo. Pisai chinhu nokuti nyore chaizvo. Izvi rikauya kazhinji kunokonzerwa inodzidzisa uyo unobereka zvakaipa disconnection mudziyo, kudhonza ari connector kana chokuita inowanikwa. Nzira iri nyore kuedza inowanikwa kuita ndiko kubatanidza nayo pamwe mbeva. Zvisinei, izvi ndizvo zvakaoma kuwana mufananidzo wakakwana, sezvo achifurira anoshandisa chete nehafu chiratidzo akarongwa masere. Chete kushandiswa rinokosha chivhariso uye kubvumira purogiramu kuti aone chokupika. Nokuti chinangwa ichi chiripo kare zvikuru dzakabudirira software.
