Software xav tau kev pab
Cov khoom siv Nucleo tswj thiab sib txuas lus nrog X-NUCLEO-ISO1A1 pawg thawj coj ntawm GPIOs. Qhov no yuav tsum tau siv ntau lub GPIOs rau kev tawm tswv yim, tso tawm, thiab kev ua txhaum ntawm cov khoom siv IO muaj nyob hauv X-NUCLEO-ISO1A1 pawg thawj coj saib. Xa mus rau Hardware neeg siv phau ntawv UM3483 kom paub meej ntxiv thiab cov kev teeb tsa jumper.

Kev teeb tsa lub rooj tsavxwm (board_config.h)
Lub board_config.h file txhais cov peev txheej siv thiab kev teeb tsa macros los teeb tsa software raws li pawg thawj coj teeb tsa. Nws ua haujlwm txog li ob lub rooj tsavxwm (xws li stacking ntawm ob lub rooj tsavxwm).
Lub software DEFAULT configuration yog ua raws li X-NUCLEO-ISO1A1 expansion board nrog nws jumpers nyob rau hauv lub neej ntawd txoj hauj lwm. Txhawm rau teeb tsa cov software rau X-NUCLEO-ISO1A1 hauv nws qhov chaw teeb tsa, tsis hais BOARD_ID_DEFAULT macro hauv board_config.h file.

Thaum khiav tsuas yog ib lub rooj tsavxwm, xyuas kom meej tias cov software raug teeb tsa rau ib qho kev teeb tsa thiab cov macro sib raug rau lwm qhov kev teeb tsa tau tawm tswv yim.

Pre-scalers
Peb tuaj yeem teeb tsa cov txiaj ntsig ua ntej hauv board_config.h kom ua tiav qhov sib txawv ntau zaus rau PWM cov zis los ntawm kev teeb tsa cov macro tsim nyog. Txhawm rau siv tus nqi pre-scalar, uncomment tus coj macro thiab tawm tswv yim rau lwm tus. Los ntawm lub neej ntawd, DEFAULT_PRESCALAR yog siv.

• PRESCALER_1
• PRESCALER_2
• DEFAULT_PRESCALER

Thaum nws tsis siv lossis ib qho haujlwm uas cuam tshuam nrog LEDs raug hu, macro yuav tsum tsis txhob hais.

Input thiab output GPIO configuration
Txhua X-NUCLEO-ISO1A1 board yog nruab nrog ob qhov chaw nres nkoj thiab ob qhov chaw tso zis. Lub peev xwm ntawm lub rooj tsavxwm tuaj yeem nthuav dav los ntawm kev teeb tsa ob lub X-NUCLEO-ISO1A1 boards nyob rau sab saum toj ntawm ib leeg, yog li ua kom siv plaub lub tswv yim digital ports thiab plaub qhov chaw tso tawm digital.
