Hi, I was trying to configure the Delay Block on the STM32H723xx for the Octo-SPI (in my case OCTOSPI2). The datasheet documentation on that part is quite simple with 6 steps, but I get stuck at the Line Length Valid Flag. After the first round (unit...
Microcontroller STM32F401. The DMA controller transfers data from memory to the DR register of the SPI interface. With the HTIE and TCIE bits set, DMA is not included in the interrupt handler. At the end of the data array transfer, the program freeze...
Hello everyone,I have an issue regarding an always true condition produced by the following code.Since I have never run into this kind of issue with C I guess it must have something to do with the STM environment.The condition within the if-statement...
Hi, I have a problem with the HAL_UARTEx_ReceiveToIdle_DMA() function. I'm using this simple codemain.c:#define TM_BUS_DATA_RX_BUFFER_SIZE 256 uint8_t TM_BUS_DATA_RX_BUFFER[TM_BUS_DATA_RX_BUFFER_SIZE] = {0x00};HAL_UARTEx_ReceiveToIdle_DMA(&huart3, T...
Hi everyone!I've been trying to implement UART reception using LL library in polling mode. The code below is what handles the reception: uint8_t LL_USART_Receive_Byte(USART_TypeDef *USARTx) { // Wait for Read Data Register is not empty while (!LL_U...
So I am using STM32H725 on which I have Timer 2 (general purpose timer) which is in down counting, one pulse mode with an interrupt which is triggered at underflow. Once the interrupt is fired, the TIMx_CNT register value is changed and then __HAL_TI...
Hello,according to the product selector on the ST website, the only MCU from L412 series that has SMPS and is in production is STM32L412RB with 64 pins in LQFP and UFBGA package.In the product specification v6, on p57 at the PIN definitions table, I ...
Is it reasonable to consider using an STM32 for new product designs. Can't find any official statements of if and when any microcontroller will be available through official channels/distributors.
Hello Everyone!Wanted to ask because I have a problem with getting the z pulse, or index channel to work on my encoder. I am using an encoder on a motor, and a nucleo board, and programming everything on stm32cubeide.What is the correct way of doing ...
