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...
I use STM32746G-Discovery to learn usb msc.I copied STM32Cube_FW_F7_V1.15.0\Projects\STM32746G-Discovery\Applications\USB_Device\MSC_Standalone and it works fine.but when i use Freertos to drive msc, the PC popup a dialog that the device can't be re...
The STM32H742xI/G STM32H743xI/G data sheet (DS12110 Rev 7) implies VDDLDO can be supplied separately from VDD. “When it is not available on a package, the VDDLDO pin is internally tied to VDD.�? And “VDDLDO ≤ VDD�?. However, on the STM32H743VIH6, VDD...
Hi!I have a Nucleo F401RE that works great! But the problem I have is that the board cannot be call the function HAL_UART_RxCpltCallback after it has recieve its bytes.I have:Using DMAEnable global interuptUsing USART2Calling DMA inside HAL_UART_RxCp...
Hi there!I hope someone can help me. Afther a couple of years i start again to program the STM32 microcontroller (STM32F051). I need the use a UART for trasmit and receive data. For the trasmission no problem work weel ( i use the interrup HAL functi...
Hi,I am trying to understand DMAMUX possibilities and usage.My target is to implement auto refresh of external muxed (scanning) SPI LED display. Just 3 shift registers in daisy chain. 1 byte selects current characters (mux) and 2 bytes are contents o...
@The things i use:Hardware: Stm32F446RESoftware: CubeMX V.5.4 ; Matlab R2019b ; CubeIDE V.1.1 ; Mat-Target My Question is: Where is the Mistake in my Programm. I defined the PA5 as a Gpio output because that´s the Output for the LD2 LED on my board w...
I would like to send data with modulation "B-PSK coded with Peak Noise Avoidance". Most of the time I receive instead of DL_DataConfirm a response DL_DataError with error cause 0x08. Unfortunately, that error code is not documented in user manual. Co...
The STM32F469IG needs to be interfaced with the ISSI IS16100H-7TL (512K x 16 bits x 2 Banks, 16Mbit SDRAM). This SDRAM has 12 address inputs, A0 - A11.Should the SDRAM controller in the MCU being configured for 12 bit address and connect FMC_A0-A11of...
In my STM32H7 application I start a timer, stop it in an update interrupt handler (by setting ARR to 0), then when appropriate I set a new ARR value thus restarting the timer. This happens very frequently. During each such period I execute a number o...
Hi,I am using STM32H753 controller in my design, I am measuring the current consumption in vbat mode with the battery and found it to be around 1uA. The RTC Configuration was RTC_Alarm_A enabled.But disable the Alarm_A in the RTC configuration, the c...
