STM32 HAL DRIVER ATOLLIC TRUESTUDIO CODE
Build the code by pressing Ctrl-Shift-B:.You can find the GPIO pin numbers and the alternate function numbers corresponding to the UART interface on your device by searching the datasheet for the Alternate Function Mapping section: For STM32F410RB connecting UART2 to pins PA2 and PA3 requires enabling alternate function #7. We are using UART2 and pins PA2 and PA3 as the Nucleo-F410RB board has them connected to the on-board ST-Link UART interface, so we can use a terminal to interact with the board.HAL_UART_Transmit(&s_UARTHandle, buffer, sizeof(buffer), HAL_MAX_DELAY) HAL_UART_Receive(&s_UARTHandle, buffer, sizeof(buffer), HAL_MAX_DELAY) If (HAL_UART_Init(&s_UARTHandle) != HAL_OK) GPIO_InitStructure.Mode = GPIO_MODE_AF_OD HAL_GPIO_Init(GPIOA, &GPIO_InitStructure) GPIO_InitStructure.Speed = GPIO_SPEED_HIGH
GPIO_InitStructure.Alternate = GPIO_AF7_USART2 GPIO_InitStructure.Mode = GPIO_MODE_AF_PP Static UART_HandleTypeDef s_UARTHandle = UART_HandleTypeDef() Replace the code in your main source file with the following: Initializing the UART module by specifying the operating parameters.Configuring the GPIO pins corresponding to UART to actually act as UART pins (as opposed to manually controlled GPIO) pins.Enabling the clocks for the UART and GPIO peripherals.We will begin with a simple program that will read bytes via UART and echo them back in groups of 4. Connect your board to USB and let VisualGDB automatically recognize it and configure debug settings:.Proceed with the default “LEDBlink (HAL)” sample:.We will use the Nucleo-F410RB board that has the STM32F410RB chip: On the next page select your STM32 device.Select “Create a new project with MSBuild -> Embedded Binary”:.
STM32 HAL DRIVER ATOLLIC TRUESTUDIO HOW TO
We will show how to use direct mode, interrupt-based mode and DMA-controlled mode and will use a logic analyzer to compare the precise timings of various events.īefore you begin, install VisualGDB 5.2 or later. This tutorial shows how to use the STM32 UART interface in different modes using the HAL libraries.
