I-port bit ye-I/O icwangciswa ngokukhululekileyo, nangona kunjalo iirejista ze-I/O kufuneka zifikelelwe njengamagama angama-32-bit, amagama anesiqingatha okanye ii-bytes. Injongo yerejista yeGPIOx_BSRR kukuvumela ukufunda/ukuguqula iatomic ukufikelela kuyo nayiphi na irejista yeGPIOx_ODR. Ngale ndlela, akukho mngcipheko wokuba kwenzeke i-IRQ phakathi kokufunda kunye nokufikelela kohlengahlengiso.
Umzobo we-70 kunye noMzobo we-71 ubonisa izakhiwo ezisisiseko zomgangatho kunye ne-5-Volt i-port bit ye-port ye-O / O, ngokulandelanayo. Itheyibhile 92 inika uqwalaselo kancinci lwezibuko olunokwenzeka.

I-VDD_FT yinto enokuthi ibekho kwi-I/Os enevolthi ezintlanu kwaye yahlukile kwi-VDD.

GP = injongo-jikelele, PP = tyhala-tsala, PU = tsala-phezulu, PD = tsala-phantsi, OD = ukuvula-drain, AF = omnye umsebenzi

Injongo ngokubanzi I/O (GPIO)
Ngexesha nasemva nje kokusetwa kwakhona, eyenye imisebenzi ayisebenzi kwaye uninzi lwezibuko ze-I/O ziqwalaselwe kwimo ye-analog.

Izikhonkwane ze-debug zikwi-AF tsala-phezulu/yokutsalela phantsi emva kokusetha ngokutsha:

• PA15: JTDI ekutsaleni-up
• PA14: JTCK/SWCLK ekutsaleni-phantsi
• PA13: JTMS / SWDAT ekutsaleni-up
• PB4: NJTRST ekutsaleni-phezulu
• PB3: JTDO ikwimo edadayo

Xa i-pin iqwalaselwe njengemveliso, ixabiso elibhaliweyo kwirejista yedatha yemveliso (GPIOx_ODR) iphuma kwi-I / O pin. Kuyenzeka ukuba usebenzise umqhubi wemveliso kwimowudi yokutyhala okanye imowudi yokuvula i-drain (kuphela umgangatho ophantsi oqhutywayo, umgangatho ophezulu yiHI-Z).
Irejista yedatha yegalelo (GPIOx_IDR) ibamba idatha ekhoyo kwiphini ye-I/O kuwo wonke umjikelo wewotshi ye-AHB.
Zonke izikhonkwane zeGPIO zinezixhasi zangaphakathi ezibuthathaka zokutsalwa phezulu kunye nokutsalwa phantsi, ezinokuthi zisebenze okanye zingaxhomekeke kwixabiso kwirejista yeGPIOx_PUPDR.

I/O pin alternate function multiplexer kunye nemephu
Izikhonkwane ze-I / O zesixhobo zixhunywe kwii-peripherals / iimodyuli zebhodi ngokusebenzisa i-multiplexer evumela kuphela enye i-peripheral alternate function (AF) exhunywe kwi-I / O pin ngexesha. Ngale ndlela, akunakubakho ngquzulwano phakathi kweeperipherals ezikhoyo kwiphini ye-I/O efanayo. I-I/O pin nganye ine-multiplexer efikelela kwishumi elinesithandathu legalelo elitshintshanayo (AF0 ukuya ku-AF15) elinokulungiswa ngeGPIOx_AFRL (yephini 0 ukuya ku-7) kunye ne-GPIOx_AFRH (ye-pin 8 ukuya kwi-15) iirejista:

• Emva kokusetha kwakhona ukhetho lwe-multiplexer ngumsebenzi ongomnye ongu-0 (AF0). Ii-I/Os ziqwalaselwe kwenye indlela yokusebenza nge-GPIOx_MODER irejista.
• Izabelo ezithile ezizezinye ezizezinye zephini nganye zicacisiwe kwidatha yedatha yesixhobo.
• I-Cortex-M7 eneFPU EVENTOUT yenziwe kwimephu ye-AF15
  Ukongeza kobu bubhetyebhetye be-I/O yolwakhiwo lwe-multiplexing, i-peripheral nganye ineminye imisebenzi eboniswe kwii-I/O pins ezahlukeneyo ukunyusa inani leeperipherals ezikhoyo kwiipakethe ezincinci.
  Ukusebenzisa i-I/O kuqwalaselo olunikiweyo, umsebenzisi kufuneka aqhubeke ngolu hlobo lulandelayo:
• Debug umsebenzi: emva kokuba isixhobo ngasinye sisetwe ngokutsha, ezi zikhonkwane zikwabelwa njengezinye izikhonkwane zomsebenzi ezisetyenziswa ngoko nangoko ngumamkeli wedebugger.
• Umsebenzi weNkqubo: Izikhonkwane ze-MCOx kufuneka ziqwalaselwe kwenye indlela yokusebenza.
• GPIO: qwalasela i-I/O efunekayo njengemveliso, igalelo okanye i-analog kwirejista yeGPIOx_MODER.
• Umsebenzi ongomnye we-peripheral:
  • Qhagamshela i-I/O kwi-AFx oyifunayo kwenye ye-GPIOx_AFRL okanye irejista ye-GPIOx_AFRH.
  • Khetha uhlobo, tsala-phezulu/utsalo-phantsi kunye nesantya semveliso ngeGPIOx_OTYPER, GPIOx_PUPDR kunye neGPIOx_OSPEEDER iirejista, ngokulandelelana kwazo.
  • Qwalasela i-I/O efunekayo njengolunye umsebenzi kwirejista yeGPIOx_MODER.
• Imisebenzi eyongezelelweyo:
  • Kwi-ADC kunye ne-DAC, qwalasela i-I / O efunekayo kwimodi ye-analog kwirejista ye-GPIOx_MODER kwaye uqwalasele umsebenzi ofunekayo kwiirejista ze-ADC kunye ne-DAC.
    Njengoko kubonisiwe ngasentla, kwimisebenzi eyongezelelweyo (efana neDAC okanye i-OPAMP), imveliso ilawulwa yi-peripheral ehambelanayo. Ukunyamekela kufuneka kuthatyathwe ukukhetha umsebenzi we-analog ye-port ye-I / O ngaphambi kokwenza umsebenzi owongezelelweyo kwirejista yokulawula i-peripheral.
  • Ngemisebenzi eyongezelelweyo efana ne-RTC_OUT, RTC_TS, RTC_TAMPx, WKUPx kunye ne-oscillators, qwalasela umsebenzi ofunekayo kwi-RTC enxulumene, i-PWR kunye ne-RCCregisters. Le misebenzi inokubaluleka ngaphezu koqwalaselo kwiirejista eziqhelekileyo zeGPIO. Ukufumana iinkcukacha malunga nokulawulwa kwe-I / O yi-RTC, bhekisa kwiCandelo 46.3: Inkcazo yokusebenza kwe-RTC kwiphepha le-1924.

Iirejista zokulawula izibuko ze-I/O

Ngalinye izibuko GPIO ine bit-32 iirejista yolawulo memory-mapped ezine (GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR) ukuqwalasela ukuya 16 I/Os. Irejista yeGPIOx_MODER isetyenziselwa ukukhetha indlela ye-I/O (igalelo, imveliso, i-AF, i-analog). Iirejista zeGPIOx_OTYPER kunye neGPIOx_OSPEEDR zisetyenziselwa ukukhetha uhlobo lwemveliso (utyhala-tsala okanye uvule-umngxuma) kunye nesantya. Irejista yeGPIOx_PUPDR isetyenziselwa ukukhetha ukutsalwa-
phezulu/tsala-phantsi nokuba yeyiphi na indlela ye-I/O.

Iirejista zedatha ye-I/O

• I-GPIO nganye ineerejista zedatha ye-16-bit yememori yememori: iirejista zedatha yegalelo kunye nemveliso (GPIOx_IDR kunye neGPIOx_ODR). I-GPIOx_ODR igcina idatha ukuba ikhutshwe, iyafundeka / ibhale ifikeleleke. Ukufakwa kwedatha nge-I/O kugcinwe kwirejista yedatha yegalelo (GPIOx_IDR), irejista yokufunda kuphela.
• Jonga iCandelo 11.4.5: Irejista yedatha ye-GPIO ye-port (GPIOx_IDR) (x = A ukuya ku-K) kunye
• Icandelo 11.4.6: Irejista yedatha ye-GPIO port (GPIOx_ODR) (x = A ukuya ku-K) kwiinkcazo zerejista.

I/O data bitwise handling

• Irejista yokuseta kancinane (GPIOx_BSRR) yirejista yeebhithi ezingama-32 evumela usetyenziso ukuseta nokuseta ngokutsha isuntswana ngalinye kwirejista yedatha yemveliso (GPIOx_ODR). Irejista yokuseta kancinane inobukhulu obuphindiweyo be-GPIOx_ODR.
• Kwibit nganye kwi-GPIOx_ODR, hambelana namasuntswana olawulo amabini kwi-GPIOx_BSRR: BS(i) kunye ne-BR(i). Xa ibhalelwa ku-1, bit BS(i) icwangcisa i-ODR (i) bit ehambelanayo. Xa ibhalelwa ku-1, bit BR(i) iphinda imisele i ODR(i) bit ehambelanayo.
• Ukubhala nayiphi na intwana ukuya ku-0 kwi-GPIOx_BSRR ayinasiphumo kwisuntswana elihambelanayo kwi-GPIOx_ODR. Ukuba kukho umzamo wokuseta nokuseta ngokutsha kancinane kwi-GPIOx_BSRR, intshukumo emiselweyo ithatha indawo yokuqala.
• Ukusebenzisa irejista ye GPIOx_BSRR ukutshintsha amaxabiso amasuntswana ngamanye kwi GPIOx_ODR yi "one-shot" isiphumo esingatshixanga i GPIOx_ODR bits. Amasuntswana eGPIOx_ODR angasoloko efikelelwa ngokuthe ngqo. Irejista ye-GPIOx_BSRR ibonelela ngendlela yokuphatha i-atomic bitwise.
• Akukho mfuneko yokuba isoftwe ikhubaze uphazamiseko xa udwelisa iGPIOx_ODR kwinqanaba le bit: kuyenzeka ukuguqula amasuntswana enye okanye ngaphezulu kunikezelo lokubhala lweathom enye ye-AHB.

Indlela yokutshixa yeGPIO

• Kuyenzeka ukuba ngumkhenkce iirejista zolawulo lweGPIO ngokusebenzisa ulandelelwano oluthile lokubhala kwirejista yeGPIOx_LCKR. Iirejista ezikhenkcezisiweyo zezi GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR, GPIOx_AFRL kunye neGPIOx_AFRH.
• Ukubhala irejista yeGPIOx_LCKR, ulandelelwano oluthile lokubhala / lokufunda kufuneka lusetyenziswe. Xa ulandelelwano lwe-LOCK olufanelekileyo lusetyenziswa kwibit 16 kule rejista, ixabiso le-LCKR[15:0] lisetyenziselwa ukutshixa uqwalaselo lwe-I/Os (ngexesha lokubhala ngokulandelelana i-LCKR[15:0] ixabiso kufuneka libe efanayo). Xa ulandelelwano lwe-LOCK lusetyenzisiwe kwi-bit ye-port, ixabiso le-port bit alinakuguqulwa de kube yi-MCU elandelayo yokusetha ngokutsha okanye ukusetwa kwakhona kwe-peripheral. Ngamnye
• GPIOx_LCKR isuntswana imisa intwana engqinelanayo kwiirejista zolawulo (GPIOx_MODER, GPIOx_OTYPER, GPIOx_OSPEEDR, GPIOx_PUPDR, GPIOx_AFRL kunye neGPIOx_AFRH.
• Ulandelelwano lwe-LOCK (jonga kwiCandelo le-11.4.8: irejista yokutshixa izibuko le-GPIO
  (GPIOx_LCKR) (x = A ukuya ku-K)) inokwenziwa kuphela kusetyenziswa igama elithi (32-bit ubude) ukufikelela kwirejista yeGPIOx_LCKR ngenxa yokuba i-GPIOx_LCKR bit 16 kufuneka imiselwe ngexesha elinye njenge [15: 0] amasuntswana.
• Ukufumana iinkcukacha ezithe vetshe jonga kwinkcazo yerejista ye-LCKR kwiCandelo le-11.4.8: Irejista yokutshixa izibuko le-GPIO (GPIOx_LCKR) (x = A ukuya ku-K).
