1, Lub hauv paus ntsiab lus tso saib thiab kho vajtse lub hauv paus ntawm lub vijtsam tawg code
Segment Code Structure thiab Tsav Tsheb Logic
Cov khoom siv ntawm lub vijtsam tawg muaj ntau ntu, txhua ntu sib txuas rau ib qho hluav taws xob ywj pheej (SEG), thiab txhua ntu sib koom ua ke ib qho electrode (COM). Ua tus lej 8- zoo li tus lej ua piv txwv, nws muaj 7 ntu ntu (AG) thiab 1 tus lej lej ntu ntu (DP), thiab tau qhib thiab kaw los ntawm kev tswj hwm qhov sib txawv ntawm SEG thiab COM. Piv txwv li, tso saib tus naj npawb "8" yuav tsum tau tag nrho 7 kab mob stroke yuav tsum tau teeb ib txhij, thaum tso saib "1" tsuas yog teeb rau ntu b thiab c.
Cov neeg tsav tsheb chips (xws li HT1622, TM1621) tswj cov ntu ntu code npo los ntawm lub sijhawm- faib dynamic scanning, thiab lub voj voog lub luag haujlwm thiab kev tsis ncaj ncees ntawm txhua COM txiav txim siab cov zaub thiab qhov sib txawv. Piv txwv li, HT1622 txhawb nqa 1/4 lub voj voog lub luag haujlwm thiab 1/3 kev tsis ncaj ncees, thiab tuaj yeem tsav mus txog 32 SEGs thiab 8 COMs, ua rau nws tsim nyog rau cov khoom siv sib txawv.
Kev siv lub cev ntawm cov lej lej thiab cov cim
Tus lej lej (DP) ua haujlwm raws li ntu kev ywj pheej, thiab nws cov zaub nyob ntawm qhov kev tso npe ntawm tus tsav nti. Hauv daim ntawv thov raug siv ntawm HT1622, COM0-COM7 sib raug rau COM1-COM8 ntawm lub vijtsam tawg, thiab SEG0-SEG10 sib raug rau SEG1-SEG11 ntawm lub vijtsam tawg. Txhawm rau tso saib tus lej lej, qhov sib thooj SEG sau npe me ntsis yuav tsum tau teeb tsa rau qib siab. Piv txwv li, thaum tso saib "12.34", ntu DP ntawm tus lej thib ob yuav tsum tau teeb ib txhij.
Kev siv cov cim (xws li chav tsev "degree" thiab cov xib xub taw qhia) yuav tsum tau siv cov yeeb yaj kiab pwm rau cov kab lis kev cai, uas ua ke cov kab mob stroke ntawm cov cim rau hauv iav substrate. Piv txwv li, lub cim "degree" ntawm tus pas ntsuas kub tuaj yeem tuav SEG thiab COM cov peev txheej ntxiv thiab yuav tsum tau tswj hwm nyias hauv cov tsav tsheb logic.
2, Kev sib tw ntawm kev nthuav qhia cov lej lej thiab cov cim
Sau npe cov kev txwv ntawm cov tsav tsheb chips
Cov ntawv sau npe me ntsis dav ntawm qee tus tsav tsheb yuav txwv cov zaub ntawm cov lej lej lossis cov cim. Piv txwv li, nyob rau hauv ib qho xwm txheej, SEG3 / SEG4 / SEG9 / SEG10 ntawm HT1622 yuav tsis tso tawm ob qho tib si sab saum toj thiab hauv qab kab thaum sau qhov siab tshaj plaws, tej zaum vim yog sau npe me ntsis tsis sib haum xeeb lossis lub sijhawm yuam kev. Hom teeb meem no yuav tsum tau daws los ntawm optimizing tus tsav tsheb code, xws li refreshing upstream thiab downstream cov ntaub ntawv nyob rau hauv ib lub sij hawm- sib qhia yam kom tsis txhob sau cov kev tsis sib haum xeeb ntu ib txhij.
Kev cuam tshuam ntawm lub luag haujlwm voj voog ntawm dynamic scanning
Lub luag hauj lwm lub voj voog ntawm lub sij hawm- faib scanning ncaj qha cuam tshuam rau kev ruaj ntseg ntawm tus lej lej zaub. Yog tias lub voj voog ua haujlwm tsawg dhau (xws li 1/8), tus lej lej yuav flicker vim tsis txaus refresh tus nqi. Cov tshuaj muaj xws li:
Xaiv lub voj voog tsav tsheb loj (xws li 1/4 lossis 1/3);
Ua kom zoo dua qhov kev txiav txim scanning thiab ua kom muaj qhov tseem ceeb ntawm cov ntu uas muaj cov lej lej;
Ua kom cov zaub cache kom txo tau -lub sij hawm xam latency.
Customization nqi ntawm cov cim
Cov zaub ntawm cov cim yuav tsum tau tsim ua ntej ntawm cov yeeb yaj kiab pwm rau ntu ntu code cov ntxaij vab tshaus, uas ua rau tus nqi ntawm pwm ua. Rau cov khoom me me, cov cim yooj yim tuaj yeem ua tiav los ntawm kev sib txuas cov ntu uas twb muaj lawm (xws li siv "-" los qhia qhov tsis zoo). Piv txwv li, ib qho voltmeter qhia txog qhov tsis zoo los ntawm kev rov qab siv b ntu ntawm tus lej "1", txuag cov peev txheej rau cov cim kev ywj pheej.
3, Cov xwm txheej ntawm daim ntawv thov thiab kev daws teeb meem
Multi parameter zaub ntawm kev lag luam twj paj nruag
Nyob rau hauv ntau qhov kev lag luam cov twj paj nruag, qhov kev cuam tshuam lub vijtsam yuav tsum tso saib qhov muaj nuj nqis, chav nyob, thiab cov cim xwm txheej ib txhij. Piv txwv li, lub ntsuas siab yuav tsum tso saib "12.34 MPa ↑", qhov "MPa" yog chav tsev thiab "↑" yog qhov xwm txheej xub xub. Kev daws:
Siv cov chips tsav tsheb SEG siab (xws li TM1640 txhawb 64 SEG);
Customize segment code screen rau integrate units thiab cov cim rau hauv ib cheeb tsam ruaj;
Los ntawm kev tsav tsheb logic kom rov kho qhov tseem ceeb thiab cov cim nyob rau hauv ib lub sij hawm - sib faib, kev tsis sib haum xeeb yuav zam tau.
Kev sib tham sib interface ntawm cov neeg siv khoom siv hluav taws xob
Lub disconnect screen ntawm lub ntse bracelet yuav tsum tso saib lub sij hawm, kauj ruam, thiab icons (xws li lub plawv dhia thiab lub tswb moos). Vim muaj qhov chaw tsawg, nws yog ib qho tsim nyog kom ua tiav cov ntsiab lus ntau yam los ntawm kev txheeb xyuas dynamic thiab rov siv lub cim. Piv txwv li:
Nkaum kauj ruam icon thaum tso saib lub sij hawm;
Flashing lub plawv dhia icon thaum suav cov kauj ruam tso tawm;
Siv ob lub tshuab buffering los txo cov latency tshiab.
Kev ntseeg tau tsim ntawm Automotive Instruments
Lub tsheb ntsuas vaj huam sib luag yuav tsum tau tso saib ruaj khov ntawm qhov kub thiab txias (-40℃~ 85 degree). Qhov kev ntseeg tau tsim ntawm qhov tawg code screen suav nrog:
Xaiv lub nti dav dav tsav tsheb (xws li HT1621B txhawb nqa -40℃~ 105 degree);
Ntxiv ESD tiv thaiv Circuit Court los tiv thaiv electrostatic puas tsuaj rau SEG/COM;
Optimize backlight tsav los xyuas kom meej nyeem tau nyob rau hauv lub teeb muaj zog.
