Hi, I'm not being able to make LPUART work.What I tried:Use HAL drivers.Clock LPUART with LSE.Use different board.I also configured PB11 as output and it toggles normally.PB11: TX(output)PB10: RX(input)This is my code:LL_IOP_GRP1_EnableClock( LL_IOP_...
We have a system that uses hundreds of modules. Each module has 4 STM32F303 MCU's. Within a single module we would like to have one programming interface. Is there a means to program 4 MCUs with one programming interface?
Hi everyone,I can write to flash of STM32F103, max value of uint32 variable 4294967294.It is possible to write when you write it to flash directly.But I want to write it to flash with uart receiving. But when I put the rows (which is writed Bold in c...
Hello,I'm trying to understand: When will the HAL_UART_Receive function return HAL_TIMEOUT ?Will it happen only when the "Timeout" value has passed ?/** * @brief Receive an amount of data in blocking mode. * @note When UART parity is not enable...
There's an error either in the datasheet and CubeMX or in the IBIS and BXL files.In the datasheet and CubeMX, J14 pin on STM32H745IIK6 (UFBGA 176+25) is labeled as VSS, but in the BXL file (Altium SchLib) and in the IBIS file, it is labeled as VDD.Co...
I'm trying to run the aws_demos project from X-CUBE-AWS on the B-L4S5I-IOT01A development board. I've successfully programmed and run the provisioning image. I've successfully built the aws_demos project, and have the "B-L4S5I-IOT01_aws_demos.sfb" an...
As per CAN new API i have implemented as followed sequence:-MX_CAN1_Init();CAN_filterConfig(); if (HAL_CAN_Start(&hcan1) != HAL_OK) { Error_Handler(); } if (HAL_CAN_ActivateNotification(&hcan1, CAN_IT_RX_FIFO0_FULL |CAN_IT_TX_MAILBOX_EMPTY) != HAL_O...
I am working on STM32H743 series, and I want to do Write operation continuously. When the flash is erased by STM32CubeProgrammer it returns 0xFF, but after erasing with HAL API (HAL_FLASHEx_Erase()), I got the value other than 0xFF (i.e previously fl...
Hello,Ive looped a datatransfer between STM32 SPI Master Port (on SPI3) to a slave port (on SPI2) on the same STM32 MCU. When I use DMA to send (from Master port) the data in blocks of 15 bytes, the data is not properly received on the SPI2 rx buffer...
Hi I am using B-L072Z-LRWAN1 board and connected ToF sensor to I2C1 (PB8 and PB9).I am using the following I2C configuration: __HAL_RCC_I2C1_FORCE_RESET(); __HAL_RCC_I2C1_RELEASE_RESET(); I2cHandle1.Instance = ( I2C_Ty...
