Hi I am trying to read car CAN BUS with STM32F091RC + MCP2551 transreceiver. All I am getting is empty header and data. I guess my setup is incorrect, anyone can advice how to setup?This is my setup: CAN_TxHeaderTypeDef TxHeader; CAN_RxHeaderTypeD...
Hi there,I would like to ask for some help or advice to fix the below:I want to flash/ update the firmware (.dfu file) of my LILYGO TTGO T-Motion/softRF Dongle which runs on STM32 S76G Lora Chip by using DfuSe DemoUnfortunately the device is recogniz...
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 ...
