STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello everybody:i'm trying to implement modbus function on mcu(stm32F4)my structure as followingi receive data from usart6 by HAL_UART_Receive_DMA function(circular mode)it's work when just only one MCU edge. but if two mcu edge (two modbus slave),...
I don't use CubeMX - I write to all the SPI registers directly.STM32F030C8I have SPI1->CR2->DS set as 7 (8 bit data transmit) but the CPU is transmitting 16 bits for each write to the SPI1->DR register.I verify this using a logic analyzer.I can't fin...
Hi,I am using the stm32L100RBT6 and I have successfully implemented the stop mode.I have chosen to wake up the µC from stop mode either by RTC or by an external interrupt.Before I put the µC in stop mode, I set all the pins to analog to save power an...

Hi,we have a problem with low power application developed on STM32L452RE with BLE BlueNRG-M2SA module to read environmental sensors (STTS751, HTS221 and LPS25)The application is developed on the STM32CubeIDE (1.5.1)At the start of main code the IWDG_...
I'm somewhat new to scatter files and I'm trying to understand them better by doing some tests on a ST32F765 project (with 2mb flash at 0x0800 0000 - 0x081F FFFF).This scatter file works OK:LR_IROM2 0x08100000 0x00100000 { ; load region size_regi...
rxBuf is uint8_t array. // this creats HardFault sometimes: id = *(uint32_t *)&rxBuf[i]; //---------------------------------------------------- // but this works OK forever: id = rxBuf[i + 3]; id <<= 8; id += rxBuf[i + ...
What happened to the equivalent of I2S_FLAG_CHSIDE as I don't seem to be able to find it.Or do you just count the interrupts and assume it goes Left - Right - Left... forever?ThanksAndy.
Where can I find the default values for the option bytes? I'm using a STM32L151CCI mean the option byte values stored in the factory on delivery.
