Realizuje kurs: https://forbot.pl/blog/kurs-stm32-f4-5-pomiar-napiecia-adc-dma-stmstudio-id13099 Pomiar temperatury przez ADC bez przerwania działa super. W momencie jak dołożyłem przerwania uC wykonuje raz tą operacje i wchodzi do obsługi przerwania. Inaczej mówiąc dokonuje pomiaru tylko raz, klikając reset dokonuje go znowu nie robi tego cyklicznie sam. Z czego wynika problem?

arasu Październik 31, 2020 Udostępnij Październik 31, 2020 Ja bym dorzucil HAL_ADC_Start_IT(&hadc1); na koniec przerwania ADC, jak to nic nie da to bym sprawdzal dalej przez debuger co sie dzieje na rejestrach ADC. Ewentualnie sprawdzilbym jeszcze co robi ta flaga hadc1.Init.EOCSelection = ADC_EOC_SINGLE_CONV; z F4 ostatnio malo co sie bawilem, takze nie pamientam co za ficzery ma tamtejszy ADC.
