MCX Nx4x TSI tsananguro yebasa
Heino tsananguro yeaya achangowedzerwa maficha:
- Iyo nzira dzepedyo dzinobatanidza basa
- Basa repedyo rinoshandiswa kubatanidza akawanda TSI chiteshi chekuongorora. Gadzirisa TSI0_GENCS[S_PROX_EN] ku 1 kuti igone kugonesa nzira yepedyo, kukosha mu TSI0_CONFIG[TSICH] haashandi, haashandiswe kusarudza chiteshi mune zviri pedyo.
- Iyo 25-bit register TSI0_CHMERGE[CHANNEL_ENABLE] yakagadziridzwa kuti isarudze machanera akawanda, iyo 25-bit inodzora kusarudzwa kwemachanera makumi maviri neshanu eTSI. Inogona kusarudza kusvika kumatanho makumi maviri neshanu, nekugadzirisa 25 bits ku25 (25_1_1_1111_1111_1111_1111b). Kana chinokonzeresa chikaitika, machanera akawanda akasarudzwa neTSI1111_CHMERGE[CHANNEL_ENABLE] anoongororwa pamwe chete uye oburitsa imwe seti yeTSI scan value. Iko kukosha kwe scan kunogona kuverengwa kubva murejista TSI1111_DATA[TSICNT]. Iyo yepedyo yekubatanidza basa ne theoretically inobatanidza kugona kwematanho akawanda uye yobva yatanga kuongorora, iyo inongoshanda mu-self-cap mode. Iyo yakawanda yekubata nzira inosanganiswa inogona kuwana ipfupi yekuongorora nguva, iyo idiki kukosha kwekutarisa, uye kuderera kwekunzwa. Naizvozvo, kana kubata kwaonekwa, yakawanda yekubata capacitance inodiwa kuti uwane iyo yepamusoro senitivity. Iri basa rakakodzera kune yakakura-nzvimbo yekubata kubata uye yakakura-nzvimbo yekuona padhuze.
- Baseline auto-trace basa
- Iyo TSI yeMCX Nx4x inopa rejista yekuseta hwaro hweTSI uye yekutanga trace basa. Kana iyo TSI channel software calibration yapera, zadza kukosha kwekutanga muchikamu cheTSI0_BASELINE[BASELINE]. Mavambo ekutanga echiteshi chekubata muTSI0_BASELINE[BASELINE] rejisita anonyorwa musoftware nemushandisi. Kuseta kweiyo baseline inoshanda kune imwe chiteshi chete. Baseline trace function inogona kugadzirisa hwaro mu TSI0_BASELINE[BASELINE] rejista kuti ive pedyo ne TSI current s.ample value. Basa rekutanga retrace rinogoneswa neTSI0_BASELINE[BASE_TRACE_EN] bit, uye auto trace ratio inoiswa murejista TSI0_BASELINE[BASE_TRACE_DEBOUNCE]. Hwaro hwekutanga hunowedzerwa kana kudzikiswa otomatiki, kukosha kwekuchinja kwega kwega kuwedzera/kuderera ndeye BASELINE * BASE_TRACE_DEBOUNCE. Iyo yekutanga trace basa inogoneswa chete mune yakaderera-simba modhi uye kuseta kunongoshanda kune imwe chiteshi. Kana iyo yekubata chiteshi ichishandurwa, iyo yekutanga-inoenderana-marejista inofanirwa kugadziridzwa zvakare.
- Threshold auto-trace basa
- Chikumbaridzo chinogona kuverengerwa neIP mukati me hardware kana threshold trace ikagoneswa nekugadzirisa TSI0_BASELINE[THRESHOLD_TRACE_EN] bit kusvika 1. Huwandu hwepakati hwakaverengerwa hunoiswa ku TSI0_TSHD. Kuti uwane threshold yaunoda, sarudza threshold reshiyo muTSI0_BASELINE[THRESHOLD_RATIO]. Iyo chikumbaridzo cheiyo yekubata chiteshi inoverengerwa zvinoenderana neiyo pazasi formula mune IP yemukati. Threshold_H: TSI0_TSHD[THRESH] = [BASELINE + BASELINE >>(THRESHOLD_RATIO+1)] Threshold_L: TSI0_TSHD[THRESL] = [BASELINE – BASELINE >>(THRESHOLD_RATIO+1)] BASELINE ndiko kukosha kuri mu TSI0_BASELINE[BASELINE.
- Debounce basa
- MCX Nx4x TSI inopa iyo hardware debounce basa, iyo TSI_GENCS[DEBOUNCE] inogona kushandiswa kugadzirisa nhamba yekunze-kwe-renji zviitiko zvinogona kuunza kukanganisa. Chete kunze-kwe-range kunokanganisa chiitiko modhi inotsigira debounce basa uye kuguma-kwe-scan kukanganisa chiitiko haitsigire.
- Automatic trigger function.
- Kune matatu matatu anokonzeresa masosi eTSI, anosanganisira iyo software inokonzeresa nekunyora TSI0_GENCS[SWTS] bit, hardware inokonzeresa kuburikidza neINPUTMUX, uye otomatiki inokonzeresa neTSI0_AUTO_TRIG[TRIG_EN]. Mufananidzo 4 unoratidza iyo inokonzeresa-inogadzirwa kufambira mberi.
- Iyo otomatiki inokonzeresa basa chinhu chitsva muMCX Nx4x TSI. Ichi chimiro chinogoneswa nekuseta
- TSI0_AUTO_TRIG[TRIG_EN] kusvika 1. Kana iyo automatic trigger yabatidzwa, software trigger uye hardware trigger configuration mu TSI0_GENCS[SWTS] haichaiti. Nguva iri pakati peinokonzeresa imwe neimwe inogona kuverengerwa neinotevera formula:
- Nguva yenguva pakati pechimwe nechimwe chinokonzeresa = chinokonzeresa wachi / chinokonzeresa wachi divider * trigger wachi counter.
- Chengetedza wachi: gadzirisa TSI0_AUTO_TRIG[TRIG_CLK_SEL] kuti usarudze iyo inokonzeresa wachi.
- Trigger wachi divider: gadzirisa TSI0_AUTO_TRIG[TRIG_CLK_DIVIDER] kuti usarudze chinokonzeresa wachi.
- Trigger clock counter: gadzirisa TSI0_AUTO_TRIG[TRIG_PERIOD_COUNTER] kugadzirisa kukosha kwemutambi wewachi.
- Pawachi yeautomatic trigger clock source, imwe ilp_osc 32k wachi, imwe iFRO_12Mhz wachi kana clk_in wachi inogona kusarudzwa neTICKSEL[SEL], yogovaniswa neTICLKDIV[DIV].
- Kune matatu matatu anokonzeresa masosi eTSI, anosanganisira iyo software inokonzeresa nekunyora TSI0_GENCS[SWTS] bit, hardware inokonzeresa kuburikidza neINPUTMUX, uye otomatiki inokonzeresa neTSI0_AUTO_TRIG[TRIG_EN]. Mufananidzo 4 unoratidza iyo inokonzeresa-inogadzirwa kufambira mberi.
- Wachi kubva chip system wachi
- Kazhinji, Kinetis E yakatevedzana TSI inopa yemukati referensi wachi kugadzira iyo TSI inoshanda wachi.
- Kune iyo TSI yeMCX Nx4x, wachi yekushandisa haigone chete kubva kuIP yemukati, asi inogona kubva kune chip system wachi. MCX Nx4x TSI ine maviri mashandiro wachi sosi sarudzo (nekugadzirisa TSICLKSEL[SEL]).
- Sezvinoratidzwa muMufananidzo 5, imwe kubva ku chip system clock inogona kuderedza iyo TSI yekushandisa simba rekushandisa, imwe inogadzirwa kubva kuTSI yemukati oscillator. Inogona kuderedza jitter yeTSI inoshanda wachi.
- FRO_12 MHz wachi kana clk_in wachi ndiyo TSI function clock sosi, inogona kusarudzwa neTICKSEL[SEL] yopatsanurwa neTICLKDIV[DIV].
- Test munwe basa
- MCX Nx4x TSI inopa bvunzo yemunwe basa iro rinogona kutevedzera kubata kwemunwe pasina chaiyo yemunwe kubata pabhodhi rehardware nekugadzirisa rejista inoenderana.
- Iri basa rinobatsira panguva yekodhi debug uye hardware board test.
- Kusimba kwechigunwe chekuedza kweTSI kunogona kugadzirwa neTSI0_MISC[TEST_FINGER], mushandisi anogona kushandura simba rekubata kuburikidza nazvo.
- Pane 8 sarudzo dzekugona kwemunwe: 148pF, 296pF, 444pF, 592pF, 740pF, 888pF, 1036pF, 1184pF. Kuedza kwemunwe kushanda kunogoneswa nekugadzirisa TSI0_MISC[TEST_FINGER_EN] kuenda ku1.
- Mushandisi anogona kushandisa basa iri kuverenga iyo hardware touchpad capacitance, iyo TSI parameter debug, uye kuita software kuchengetedza / kutadza bvunzo (FMEA). Mune software kodhi, gadzirisa chigunwe capacitance kutanga uye wozogonesa bvunzo yemunwe basa.
Exampuye shandisa kesi yeMCX Nx4x TSI nyowani basa
MCX Nx4x TSI ine chimiro cheiyo yakaderera-simba rekushandisa kesi:

Tafura 6. Performance Summary
| MCX Nx4x nhepfenyuro | ||
| 1 | SNR | Kusvikira ku200: 1 ye-self-cap mode uye mutual-cap mode |
| 2 | Overlay ukobvu | Kusvika 20 mm |
| 3 | Shield drive simba | Kusvikira ku600pF pa1MHz, Kusvikira ku200pF pa2MHz |
| 4 | Sensor capacitance range | 5pF - 200pF |
- SNR bvunzo
- Iyo SNR inoverengerwa zvinoenderana neiyo mbishi data yeTSI counter value.
- Muchiitiko kana pasina algorithm inoshandiswa kugadzirisa iyo sampinotungamirwa tsika, SNR kukosha kwe200: 1 inogona kuwanikwa mune yega-cap mode uye mutualcap mode.
- Sezvinoratidzwa muMufananidzo 14, bvunzo yeSNR yakaitwa paTSI board paEVB.
- Shield drive simba bvunzo
- Iyo yakasimba nhoo yakasimba yeTSI inogona kuvandudza kusapinda kwemvura kuita kweiyo touchpad uye inogona kutsigira yakakura touchpad dhizaini pane Hardware board.
- Kana 4 TSI shield chiteshi zvese zvagoneswa, iyo yakanyanya mutyairi kugona kwematanho enhoo inoedzwa pa1 MHz uye 2 MHz TSI inoshanda wachi mune self-cap mode.
- Iyo yakakwira iyo TSI inoshanda wachi, inodzikisira simba rekutyaira reiyo yakadzivirirwa chiteshi. Kana iyo TSI inoshanda wachi yakadzikira pane 1MHz, iyo yakanyanya simba yekutyaira yeTSI yakakura kupfuura 600 pF.
- Kuti uite dhizaini yehardware, tarisa kune mhinduro dzebvunzo dzinoratidzwa muTebhu 7.
- Tafura 7. Shield mutyairi simba bvunzo mhinduro
Shield channel on Clock Max shield drive simba CH0, CH6, CH12, CH18 1 MHz 600 pF 2 MHz 200 pF
- Overlay ukobvu bvunzo
- Kuti uchengetedze iyo yekubata electrode kubva mukukanganisa kwekunze kwezvakatipoteredza, iyo yakafukidzira zvinhu inofanira kunge yakanyatsobatanidzwa nepamusoro peiyo touch electrode. Panofanira kunge pasina mukaha wemhepo pakati peiyo touch electrode uye yakavharika.
