Posted on July 12, 2017 at 12:18Dear Sir:I am using STM32L476 and want enter shutdown mode to save power.Right now I had call MX_GPIO_Init();//this is set all GPIO to Pullup and set Input, HAL_PWREx_EnterSHUTDOWNMode();and now the power consumption ...
Posted on July 11, 2017 at 12:29Hi,I am using STM32F407IEH6 & STM32F746IGK6 boards in my application. I have 10 tasks with scheduler running in the application. -- APPLICATION has same code on both STM32F407IEH6 & STM32F746IGK6 .-- Two boards are ru...
Posted on July 10, 2017 at 11:07Hi, My question is i want to communicate through uart between stm32f030 board and inverter ,I am using rs485 converter to TTL board.communication has done through modbus protocol.Driver enable pin is high data will ...
Posted on July 13, 2017 at 07:31 hi im connecting two board that one of them is stm32f0 and i configure its usart as this below /* Enable the peripheral clock of GPIOA */ RCC->AHBENR |= RCC_AHBENR_GPIOAEN; GPIOA->MODER |= GPIO_MODER_MOD...
Posted on June 06, 2017 at 04:35 Hi, I just upgraded from F2 HAL library v1.4.0 to v1.6.0 and noticed that CAN_Receive_IT now uses two separate RxMessage buffers in its CAN_HandleTypeDef struct. One per CAN FIFO, as can be seen here: static...
Posted on June 28, 2017 at 13:58The CANX_TX_IRQ is called unexpected cause the HAL_CAN_Receive_IT enables the CAN_IT_TME. As a result every can rx irq also the can tx irq is called. This costs time and i've some other side effects in my application....
Posted on July 11, 2017 at 00:15 Hi, I have a quick question about the pull-up and the pull-down resistor. For example, I want to use the switch (S1) to control the output of the GPIO pin (PA0), and read this output to turn on/off another LED. Wh...
Posted on May 30, 2017 at 20:46 Hello, I am working with the STM32L486 chipset and we need to generate an exact 38400Hz timer. Currently we have a 5MHz or 25MHz external clock coming in but the PLL clock tree does not seem to favor getting the ex...
Posted on July 11, 2017 at 17:16I am using the STM32F413 and am trying to use CAN1 and CAN2 in a ring topology (CAN1 sends and if CAN2 doesn't get the message then I know I have a network connectivity failure). I use the latest CubeMX to generate th...
Posted on July 12, 2017 at 04:50 Hi, following scenario: I use one SD card on my pcb (4 wire sdio) with fatfs and FreeRTOS. The generated driver init function from ST looks like following (ff_gen_drv.c): uint8_t FATFS_LinkDriverEx(Dis...
