UKUSETSHA KWAYE KUNYE NEYUNITHI YOLAWULO LWEKHISHI

I-oscillator
ICrystal Oscillator
Nangona ukuhambelana noyilo lwebhodi ye-ST92F120 kugcinwa, akusakhuthazwa ukuba ufake i-resistor ye-1MOhm ngokuhambelana ne-crystal oscillator yangaphandle kwibhodi yesicelo se-ST92F124 / F150 / F250.

Ukuvuza
Ngelixa i-ST92F120 inovakalelo lokuvuza ukusuka kwi-GND ukuya kwi-OSCIN, i-ST92F124/F1 50/F250 inovakalelo lokuvuza ukusuka kwi-VDD ukuya kwi-OSCIN. Kunconywa ukuba ujikeleze i-crystal oscil-lator ngendandatho yomhlaba kwibhodi yesekethe eprintiweyo kunye nokufaka ifilimu yokugubungela ukuphepha iingxaki zomswakama, ukuba kuyimfuneko.
iwotshi yangaphandle
Nangona ukuhambelana noyilo lwebhodi ye-ST92F120 kugcinwa, kuyacetyiswa ukuba usebenzise iwashi yangaphandle kwigalelo le-OSCOUT.
I-advantagezi zi:

• isignali yegalelo eqhelekileyo ye-TTL ingasetyenziswa ngelixa i-ST92F120 Vil kwiwotshi yangaphandle iphakathi kwe-400mV kunye ne-500mV.
• i-resistor yangaphandle phakathi kwe-OSOUT kunye ne-VDD ayifuni.

I-PLL
Imo esemgangathweni
Ixabiso lokusetha kwakhona kwirejista ye-PLLLCONF (p55, i-R246) iya kuqalisa isicelo ngendlela efanayo nakwi-ST92F120. Ukusebenzisa imowudi yokuqhuba simahla kwiimeko ezichazwe kwiCandelo 1.5, i-PLLCONF[7] bit kufuneka isetwe.

IMowudi yeKloko yoKhuseleko
Ukusebenzisa i-ST92F120, ukuba isignali yewashi iyanyamalala, i-ST9 ingundoqo kunye newashi ye-peripheral imisiwe, akukho nto inokwenziwa ukuqwalasela isicelo kwindawo ekhuselekileyo.
Uyilo lwe-ST92F124/F150/F250 luzisa isignali yewotshi yokhuseleko, isicelo sinokuqwalaselwa kwindawo ekhuselekileyo.
Xa uphawu lwewotshi lunyamalala (umzekelo ngenxa yeresonator eyaphukileyo okanye eqhawulweyo), isiganeko sokuvula i-PLL senzeka.
Indlela ekhuselekileyo yokulawula esi siganeko kukwenza ukuba i-INTD0 iphazamiseke ngaphandle kwaye inike i-RCCU ngokucwangcisa i-INT_SEL bit kwirejista ye-CLKCTL.
Ukuphazamiseka kwesiqhelo okunxulumeneyo kuhlola umthombo wokuphazamiseka (jonga kwi-7.3.6 Isahluko soPhakamisa sesiZukulwana sedatha yedatha ye-ST92F124/F150/F250), kwaye uqwalasele isicelo kwindawo ekhuselekileyo.
Qaphela: Iwotshi yecala ayiyekwanga kwaye naluphi na umqondiso wangaphandle owenziwe sisilawuli esincinci (umzekelo i-PWM, unxibelelwano lwe-serial…) kufuneka lumiswe ngexesha lemiyalelo yokuqala eyenziwa luphazamiseko lwesiqhelo.

IXESHA LOMSEBENZI OWONGEZELELWEYO
I-Input Capture / Imveliso Thelekisa
Ukuze uvelise uphazamiseko lwexesha, inkqubo eyenzelwe i-ST92F120 inokufuna ukuhlaziywa kwiimeko ezithile:

• Ukuba isibali-xesha siphazamisa i-IC1 kunye ne-IC2 (OC1 kunye ne-OC2) zombini zisetyenziswa, i-ICIE (OCIE) yerejista ye-CR1 kufuneka isetiwe. Ixabiso le-IC1IE kunye ne-IC2IE (OC1IE kunye ne-OC2IE) kwirejista ye-CR3 ayibalulekanga. Ke, inkqubo akufuneki iguqulwe kule meko.
• Ukuba kufuneka uPhakamiso olunye kuphela, i-ICIE (OCIE) kufuneka imiswe ngokutsha kwaye i-IC1IE okanye i-IC2IE (OC1IE okanye i-OC2IE) kufuneka imiselwe ngokuxhomekeke kuphazamiseko olusetyenzisiweyo.
• Ukuba akukho nasinye seziPhakamiso zeSibali esisetyenzisiweyo, i-ICIE, IC1IE kunye ne-IC2IE (OCIE, OC1IE kunye ne-OC2IE) kufuneka zisetwe ngokutsha.

Imo yePWM
Isiphazamiso sesibali-xesha ngoku sinokwenziwa ngexesha ngalinye iCounter = OC2R:

• Ukuyenza, seta i-OCIE okanye i-OC2IE,
• Ukuyivala, seta kwakhona i-OCIE NE-OC2IE.

I-10-BIT ADC
Ekubeni i-ADC entsha yahluke ngokupheleleyo, inkqubo kuya kufuneka ihlaziywe:

• Zonke iirejista zedatha zi-10 bits, ezibandakanya iirejista ze-threshold. Ke irejista nganye yahlulwe yaba ziirejista ezimbini ze-8-bit: irejista ephezulu kunye nerejista esezantsi, apho kusetyenziswa kuphela i-2 eyona nto ibalulekileyo:
• Itshaneli yokuguqula isiqalo ngoku ichazwa ngamasuntswana CLR1[7:4] (Pg63, R252).
• Imijelo ye-analog watchdog ikhethwe ngamasuntswana CLR1[3:0]. Ekuphela kwemeko kukuba la majelo mabini kufuneka ahambelane.
• Iwotshi ye-ADC ikhethwe nge-CLR2[7:5] (Pg63, R253).
• Iirejista zokuphazamiseka azikalungiswa.

Ngenxa yobude obuninzi beerejista ze-ADC, imephu yokubhalisa yahlukile. Indawo ezikuyo iirejista ezintsha inikwe kwinkcazo ye-ADC kwi-ST92F124/F150/F250 Datasheet ehlaziyiweyo.
