HAL_SMARTCARD_Receive returns HAL_TIMEOUT.
Well, I use STM32 Nucleo F429Zi and Stm32 Cube IDE v. 1.0.2. I connected SmartCard and STM32 correctly (my oscilloscope shows rigth values of RST, IO and CLK) but in code i see zero filled buffer each SET/RESET iteration where ATR should be. Here's s...
Nucleo L152 HAL_I2C_Master_Transmit_IT problem
Hi all,i tested two method of I2C transmit and resulted as follow.Method 1 : HAL_I2C_Master_Transmit_DMA(&hi2c1, 0x4E, &Data_M[0], 4); Nothing come out at the logic analyserMethod 2 : HAL_I2C_Master_Transmit(&hi2c1, 0x4E, &Data_M[0], 4,1000); Data co...
Resolved! After LL_I2C_TransmitData8 the TXE flag keeps 0
I'm using STM32F103RBT6 to connetc to a OLED with I2C1.The init code is as below.static void MX_I2C1_Init(void) { /* USER CODE BEGIN I2C1_Init 0 */ /* USER CODE END I2C1_Init 0 */ LL_I2C_InitTypeDef I2C_InitStruct = {0}; LL_GPIO_Init...
USB DFU Issues - DFU Clock Recovery System
Hi there,We are designing in the STM32H753 and would like to use the factory DFU bootloader. We are able to use the bootloader on the H743 nucleo board, but on our PCB it fails to complete any actions giving a "connection to the target" lost error in...
How to communicate between STM32F427VI and SPBTLE-1S?
Hello,We are developing on STM32F427VI . We would like to communicate between the STM32F427VI and with SPBTLE-1S bluetooth device. Can we write an application on the STM32F427 to communicate with the bluetooth device without having to write an applic...

Random Usage faults running Hal code on 32F410
I have a fairly simple bit of code running in a CubeMX generated scheme, using HAL code to communicate over SPI. I run a loopback test a thousand times - sometimes it passes, other times I get an INVSTATE Usage Fault which appears (according to Keil)...
Flash Write Protection for STM32G070RB
Good Afternoon,do you have any technical example about writing in flash pages for this kind of microcontroller? We would like to implement In Application Programming possibly using the HAL library to disable WRP and then writing in a page (HAL_FLASH_...
