HAL_Delay w while psuje wyniki z GPS

DeadGeneratio · Lipiec 8, 2024

Dobry wieczór, ciekawy i irytujący problem - wstawienie dowolnej długości delay do pętli while psuje odczyty z gps-a. Dowiedziałem się o tym gdy podłączyłem RTC i zacząłem z nim pracować, wszystkie wyniki z płytki GPS nagle stały się losowe i bezwartościowe. Czy ktoś podsunie pomysł o co może chodzić? To przykład dla kodu z pustą pętlą while:

A to przykład dla kodu gdzie wpętli while jest tylko i wyłącznie HAL_Delay(200);

I dodatkowe pytanie - odpowiedziałem do swojego postu odnośnie FFT na F407 i widzę, że post nie pojawił się na szczycie, nie widać nawet dodatkowej odpowiedzi. Coś zostało zmienione na forum?

@DeadGeneratio odczytujesz to po UARCIE w przerwaniu po 1 znaku?

	HAL_UART_Receive_IT(&huart1, (uint8_t*) rxBuffer, 1);

Dodaj obsługę błędu od UARTu. Spróbuj też innej metody niż odczytywanie po 1 znaku. Np UARTex ma funkcję z odczytyweaniem do sygnału idle z DMA dla nieznanego rozmiaru danych.

Sprawdź priorytety, 0 to najwyższy. Sprawdź czy nie kłuci się z timerem od delaya.

I nie używaj delay 😄

DeadGeneratio · Lipiec 10, 2024

@Gineq poprawiłem kod na odbiór przez DMA, wszystko śmiga ładnie. No można powiedzieć, że prawie ładnie bo moduł ma rozrzut dokładności o około 100m, ale obstawiam, że to wina odbierania sygnału w mieszkaniu. Dodałem sobie także RTC oraz aktualizowanie RTC względem czasu GPS. Obecnie będę się męczył nad implementacją wyświetlacza e-ink.
