Help in writing a bare metal code for implementing a UART RX interrupt routine in SMT32F767ZI ?
I started writing embedded code 7 months back for a robotics project. Till now , I was able to handle most of the stuff with HAL libraries. I hit a snag when trying to interface with a AHRS(Microstrain CX5-25) unit. There were time when only first fe...
Resolved! STM32F107 I2C1 & I2C2
Hello,I am going to replace STM32F107 instead of F105 in my design, and as I see F107 has only one serial interface I2C1. In my case, I need both I2C1 and I2C2. Is there any way I can remap or define some pins as I2C2?Thank you.
How to calibrate ( RTC )LSE Crystal by temperature ?
I ' ve been working on a device that able to use industrial area. I must be sure that rtc clock is accurate because this device need to use RTC too much. When i researched , i did not find any code example about rtc calibration by temperature. Any su...
Resolved! STM32U585QI SPI Issue
Hi,I have successfully configured the SPI1 with following parameters and trying to transfer a single byte but it is being timed-out in HAL_SPI_Transmit as EOT is not being set.Init.Mode = SPI_MODE_MASTER;Init.Direction = SPI_DIRECTION_2LINES;Init.Dat...
I need urgent help on STM32L071 RTC power consumption. when we enable standby mode, without RTC, the current from battery is <1uA . when we enable standby mode, WITH RTC, the current from battery is ~200 uA ? Which is too high to sustain

STM32F412 TIM3 16 bit or 32 bit ?
The reference manual (RM0402, DocID028087 Rev 7, Fig 4) shows TIM3 as a 32 bit timer. However, the in the description in Section 17.2, TIM3 and TIM4 are described as 16 bit timers.Is this a mistake in Figure 4 ?Thanks
SDRAM HAL_SDRAM_WRITE_32b function not working for stm32H7.
Hello,I'm using STM32H757i-EVAL board and trying to store some data in the onboard SDRAM using stm32cubeide (1.7.0).Below is my initialization for SDRAMvoid MX_FMC_Init(void) { /* USER CODE BEGIN FMC_Init 0 */ /* USER CODE END FMC_Init 0 */ ...
Resolved! STM32F103C8, How to stop PWM signal?
Hi ST Community.I need your help. I am working on a PWM Proyect, Duty cicle must be change every period, and there is delta time where the PWM must be OFF.I am using a Timer, it fire an interrution and this interruption set a flag to 1 in order to r...
i2c1 block with DMA is not working (STM32h743) - when the first transaction is sent from master board to slave board - > the i2c1_event interrupt is triggered and it is stuck in an endless loop.
i've created 2 threads - i2c_tx_dma and i2c_rx_dma which use the HAL_I2C_Master_Transmit_DMA and HAL_I2C_Slave_Receive_DMA.I am working with 2 boards of the STM32h74 family:first board-> configured RX DMA on i2c1 block as a slave and activate HAL_I2C...
