ari logic probes mwanakomana bvunzo zviridzwa ayo anoshandiswa kudzora dhijitari logic mazinga emidziyo yemagetsi. Iwo anoshandiswa kunetsa emagetsi maseketi, Hardware, uye software nekutarisa logic kukosha pamapoinzi akasiyana dunhu. Verenga kuti udzidze zvakawanda nezve logic probe, nzira yekutenga imwe, uye mashandisiro ayo. A logic probe chishandiso chakakosha chekuongorora matambudziko mumagetsi edhijitari. Inogona kukubatsira kutsvaga zvikanganiso mudunhu. Izvo zvinobatsirawo pakugadzirisa software, kuona yakaipa kubatana, uye kukubatsira kuti unzwisise kuti otomatiki maitiro kana robhoti inoshanda sei. A logic probe inogona kubatsira kana iwe uchigara uchishanda nemamicroprocessors kana mamwe madhijitari ekudzora maseketi: ngationei zvavanoita uye kuti vanozviita sei. Ramba uchiverenga…
Zvirinani logic probes
Kana zvakadaro zvakanakisisa logic probes, tinokurudzira zvinotevera:
Chii chinonzi logic probe?
Una Logic probe chishandiso chakakosha kugadzirisa matambudziko emagetsi edhijitari. Basa rayo guru nderekutarisa magetsi aripo panzvimbo dzakasiyana-siyana mudunhu, uye kuratidza kana aya mapoinzi ari padanho repamusoro kana rakaderera. Iyo probe inogona kuona zvese zvakanaka uye zvisina kunaka voltage mazinga. A logic probe inoshandiswa kuongorora matambudziko mumagetsi edhijitari. Inogona kukubatsira kutsvaga zvikanganiso mudunhu. Izvo zvinobatsirawo pakugadzirisa software, kuona yakaipa kubatana, uye kukubatsira kuti unzwisise kuti otomatiki maitiro kana robhoti inoshanda sei. A logic probe inogona kubatsira kana iwe uchigara uchishanda ne microprocessors kana imwe dhijitari control circuitry. Inonyanya kushandiswa kutarisa voltage uye ikozvino mazinga panzvimbo dzakasiyana-siyana mudunhu.
Ko logic probe inoshanda sei?
A logic probe ine chikamu icho inoshandura mamiriro ayo (0 kana 1, CHOKWADI kana NHEMA) kana voltage ichichinja pane imwe nzvimbo mudunhu. Iyo probe ine maviri akabatana, imwe yekupinza uye imwe yekubuda. Iko kupinza kwakabatana kune voltage point uye inobuda kune chiratidzo. Chiratidzo cheprobe chinovhenekera kana voltage iri paprobe inopinza ichichinja kubva pasi kuenda kumusoro, kana kubva kumusoro kuenda pasi. Kana iyo voltage panzvimbo yakatariswa ichichinja, probe circuit inovhura kana kuvhara. Iyi shanduko yenyika inopfuudzwa kune probe inobuda uye probe chiratidzo chinovhenekera kumusoro.
Logic probes inoshandiswa kudzora mazinga emagetsi mumaseketi zvemagetsi. Iyo probe ine maviri akabatana, imwe yekupinza uye imwe yekubuda. Iyo probe yekupinda yakabatana kune voltage point uye inobuda kune chiratidzo. Kana iyo voltage panzvimbo yakatariswa ichichinja, iyo probe dunhu inoshandurawo mamiriro ayo kuratidza izvi. Iyi shanduko yehurumende inopfuudzwa kune yakabuda probe, uye probe chiratidzo chinovhenekera. Chiratidzo pane probe chinowanzo mwenje kana LED. Inogonawo kunge iri ruzha kana kutenheka.
Chii chekufunga kana uchitenga logic probe?
Paunotenga logic probe, ita shuwa kuti inogona kuita basa raunoda kuti iite. Iyo probe yaunosarudza inofanirwa kuve yakakodzera kune yako application. Chenjerera kune zvinotevera pfungwa:
- voltage levels: Mhando dzakasiyana dzelogic probes dzinogona kutarisa akasiyana voltage mazinga. Iva nechokwadi chekutenga probe inogona kutarisa mazinga evoltage mudunhu rako.
- mazinga azvino: Azvino probe inogona kushandiswa kuyera AC kana DC mafungu. Ita shuwa kuti unotenga ikozvino probe inogona kuyera ikozvino inoyerera mudunhu rako.
- Logic type inotsigirwa: Logic probes inogona kutsigira akasiyana marudzi epfungwa, senge DTL, TTL, CMOS, nezvimwe. Ita shuwa kuti inotsigira mhuri yeaya maseketi aunoda kuyedza.
- probe urefu: Ita shuwa kuti unotenga logic probe yehurefu hwakakodzera. Iwo mapfupi maprobe akanakira PCB kuyedzwa, nepo akareba anogona kushandiswa kuyedza majoi uye mamwe mahardware.
Ko logic probe inoshandiswa sei?
Kune akati wandei nzira dzekushandisa logic probe. Unogona kuishandisa kuyedza maseketi, kutsvaga zvisizvo zvikamu, kuteedzera zvakashata zvinongedzo, uye kugadzirisa matambudziko esoftware. Pano tinotsanangura maitiro ekuzviita:
- Kuongorora kwedunhu: Iwe unogona kushandisa logic probe kuyedza maseketi nekutarisa voltage iripo panzvimbo dzakasiyana siyana mudunhu. Iwe unogona ipapo kuziva matambudziko nekutarisa shanduko mumagetsi edunhu. Semuenzaniso, unogona kushandisa probe kuti uone kana dhijitari yedhijitari iri kushanda sezvaitarisirwa. Iwe unogona zvakare kutarisa kana dunhu rinofambiswa nemazvo.
- Tsvaga zvinhu zvisina kunaka: unogona kushandisa probe kutsvaga zvinhu zvisina kunaka nekutarisa voltage yavo. Semuenzaniso, iyo probe inogona kushandiswa kutarisa voltage pakubuda kwe transistor. Kana iyo transistor yakabuda isina iyo inotarisirwa voltage, unogona kunge wawana dambudziko.
- Kutsvaga kwekubatana kwakashata: Iwe unogona kushandisa logic probe kuteedzera pasi kuipa kwakabatana nekutarisa voltage pamapoinzi edunhu. Kana iwe ukaona kuti iyo voltage pane imwe nzvimbo yedunhu yakasiyana kubva kune voltage panzvimbo imwechete munharaunda yakavakidzana, iwe unogona kunge wakawana kubatana kwakaipa.
- Software Troubleshooting: Iwe unogona kushandisa logic probe kugadzirisa matambudziko esoftware nekutarisa voltage panzvimbo dzedunhu. Kana iwe ukaona kuti zvese zviri pachena padivi rehardware, zvinokwanisika kuti kusashanda kuri kukonzerwa nesoftware.
Chii chinogona logic probe monitor?
La kunetsana panzvimbo dzakasiyana yedhijitari yedunhu inogona kusiyanisa kubva ku0 kusvika ku5 volts (pakati pemamwe ma voltages). Ndiko kuti, iwo uye zero, kana yakakwirira uye yakaderera nyika sezvavanodanwa mumagetsi edhijitari. Zvakare, ramba uchifunga kuti probe inogona kutarisa mafungu anosvika gumi amps.
Zvechokwadi, unogona kutarisa zvose zvinowanzoitika yedhijitari yedunhu. Izvi zvinosanganisira magetsi ekupa, volti yepasi, iyo digital high voltage (VDH, inowanzoita 5 volts), iyo digital low voltage (VDL, 0 volts), uye chero magetsi aripo munharaunda nekuda kwezvino. Iyo probe inogona kushandiswa kutarisa voltage pakuiswa kwedunhu mhenyu, voltage pakubuda kwedunhu, kana ikozvino inoyerera nepadunhu. Iyo probe inogona zvakare kushandiswa kutarisa voltages mumaseketi anofamba.
