Здравствуйте! Проект: Организация сервера на базе Stm32f4. Добавил в проект HTML файл. Обновил с помощью программы makefsdata файл fsdata.c. Удалил устаревший fsdata.c. Однако, Отладчик ругается, что HTML файлы, загружаемые в память микроконтроллера, инициализированы одновременно в двух файлах.

Подскажите, пожалуйста, что не так?

Понял Вас. Большое Спасибо за помощь.

Если вас не затруднит, не могли бы вы разъяснить начинающему, что такое CUBE, SPL или HAL? Я раньше опирался на примеры уже готовых программ, а они были написаны в подобной форме. Что я делаю не так, и где нужно почитать, чтобы делать правильно? Спасибо

Здравствуйте! Проект: Управление отправкой и приёмом CAN сообщений через Ethernet с помощью браузера. Проблема: Не работает CAN, как на приём, так и на передачу сообщений. Судя по флагам, микроконтроллер проходит по всем строчкам инициализации CAN, заходит в функцию отправки сообщений, однако, ничего не отправляет. Коммутация рабочая. Подскажите, пожалуйста, как чинить? Инициализация: void CAN1_Config(void) { GPIO_InitTypeDef GPIO_InitStructure; /* CAN GPIOs configuration **************************************************/ /* Enable GPIO clock */ RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOB, ENABLE); /* Connect CAN pins */ GPIO_PinAFConfig(GPIOB, GPIO_PinSource8, GPIO_AF_CAN1); GPIO_PinAFConfig(GPIOB, GPIO_PinSource9, GPIO_AF_CAN1); /* Configure CAN RX and TX pins */ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP; GPIO_Init(GPIOB, &GPIO_InitStructure); /* CAN configuration ********************************************************/ /* Enable CAN clock */ RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN1, ENABLE); /* CAN register init */ CAN_DeInit(CAN1); CAN_StructInit(&CAN_InitStructure); /* CAN cell init */ CAN_InitStructure.CAN_TTCM = DISABLE; CAN_InitStructure.CAN_ABOM = DISABLE; CAN_InitStructure.CAN_AWUM = DISABLE; CAN_InitStructure.CAN_NART = DISABLE; CAN_InitStructure.CAN_RFLM = DISABLE; CAN_InitStructure.CAN_TXFP = DISABLE; CAN_InitStructure.CAN_Mode = CAN_Mode_Normal; CAN_InitStructure.CAN_SJW = CAN_SJW_1tq; /* CAN Baudrate = 1MBps (CAN clocked at 30 MHz) */ CAN_InitStructure.CAN_BS1 = CAN_BS1_6tq; CAN_InitStructure.CAN_BS2 = CAN_BS2_8tq; CAN_InitStructure.CAN_Prescaler = 2; CAN_Init(CAN1, &CAN_InitStructure); /* CAN filter init */ CAN_FilterInitStructure.CAN_FilterNumber = 0; CAN_FilterInitStructure.CAN_FilterFIFOAssignment = CAN_Filter_FIFO0; CAN_FilterInitStructure.CAN_FilterMode = CAN_FilterMode_IdMask; CAN_FilterInitStructure.CAN_FilterScale = CAN_FilterScale_32bit; CAN_FilterInitStructure.CAN_FilterActivation = ENABLE; CAN_FilterInitStructure.CAN_FilterIdHigh = 0; CAN_FilterInitStructure.CAN_FilterIdLow = 0; CAN_FilterInitStructure.CAN_FilterMaskIdHigh = 0; CAN_FilterInitStructure.CAN_FilterMaskIdLow = 0; CAN_ITConfig(CAN1, CAN_IT_FMP0, ENABLE); CAN_ITConfig(CAN1, CAN_IT_TME, ENABLE); CAN_FilterInit(&CAN_FilterInitStructure); } void NVIC_Config(void) { NVIC_InitTypeDef NVIC_InitStructure; NVIC_InitStructure.NVIC_IRQChannel = CAN1_RX0_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x0; NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x1; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); NVIC_InitStructure.NVIC_IRQChannel = CAN1_TX_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x0; NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x1; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); } Функция отправки: void ASK_1(void) { CanTxMsg TxMessage; // if (CAN_GetITStatus (CAN1, CAN_IT_TME)) // { // CAN_ClearITPendingBit(CAN1,CAN_IT_TME); ASK1_DATA0='1'; TxMessage.StdId = 0x101; TxMessage.RTR = CAN_RTR_DATA; TxMessage.IDE = CAN_ID_STD; TxMessage.DLC = 1; TxMessage.Data[0] = ASK1_DATA0; //CAN1->TSR&CAN_TSR_TXOK0; CAN_Transmit(CAN1,&TxMessage); // } } Функция приёма: void CAN1_RX0_IRQHandler(void) { CanRxMsg RxMessage; if (CAN_GetITStatus (CAN1, CAN_IT_FMP0)) { CAN_ClearITPendingBit(CAN1,CAN_IT_FMP0); CAN_Receive(CAN1,CAN_FIFO0, &RxMessage); CAN_FIFORelease (CAN1,CAN_FIFO0); READ_DATA0=RxMessage.Data[0]; READ_DATA1=RxMessage.Data[1]; READ_DATA2=RxMessage.Data[2]; READ_DATA3=RxMessage.Data[3]; Can1Flag = ENABLE; } }

На STM32F4 у меня пропускает сообщения от устройств с айдишниками от 100 до 199. CAN_FilterInitStructure.CAN_FilterNumber = 0; CAN_FilterInitStructure.CAN_FilterFIFOAssignment = CAN_Filter_FIFO0; CAN_FilterInitStructure.CAN_FilterMode = CAN_FilterMode_IdMask; CAN_FilterInitStructure.CAN_FilterScale = CAN_FilterScale_32bit; CAN_FilterInitStructure.CAN_FilterActivation = ENABLE; CAN_FilterInitStructure.CAN_FilterIdHigh = 0x100 << 5; CAN_FilterInitStructure.CAN_FilterIdLow = 0x199 << 5; CAN_FilterInitStructure.CAN_FilterMaskIdHigh = 0x700 << 5; CAN_FilterInitStructure.CAN_FilterMaskIdLow = 0;

Хорошо. Я вас понял. Главный вопрос в инициализации у меня относительно строк CAN_FilterIdHigh, CAN_FilterIdLow, CAN_FilterMaskIdHigh, CAN_FilterMaskIdLow. Я не очень понимаю, что конкретно в них писать. В них нужно писать диапазон Id? Если да, то зачем нужны какие-то скобки? CAN_FilterInitStructure.CAN_FilterNumber = 0; CAN_FilterInitStructure.CAN_FilterMode = CAN_FilterMode_IdMask; CAN_FilterInitStructure.CAN_FilterScale = CAN_FilterScale_32bit; CAN_FilterInitStructure.CAN_FilterIdHigh = 0x0000; CAN_FilterInitStructure.CAN_FilterIdLow = 0x0000; CAN_FilterInitStructure.CAN_FilterMaskIdHigh = 0x0000; CAN_FilterInitStructure.CAN_FilterMaskIdLow = 0x0000; CAN_FilterInitStructure.CAN_FilterFIFOAssignment = 0; CAN_FilterInitStructure.CAN_FilterActivation = ENABLE; CAN_FilterInit(&CAN_FilterInitStructure);

Добрый день! У меня CAN-шиной соединены 4 устройства STM32F4. Каждое из них подсоединено к компьютеру по USART для возможности вывода на экран входящих и исходящих сообщений. При отправке данных от одного устройства к конкретному другому, сообщение всё равно отображают все 4 устройства. Объясните, пожалуйста, каким образом правильно настроить адресацию и фильтрацию сообщений на STM32F4.
