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...
Hi !I'm using the stm32l452RE mcu and I use the shutdown mode. I also use the watchdog (IWDG) to reset the system if an error occurs. This IWDG is set to 4s. When I go in shutdown mode, accordly to the docs, IWDG should be off because it is clocked w...
Hi Our custom board had some issues for STOP mode.Firstly, please see the following STOP mode code:(using GPIO EXTI to wake up MCU)HAL_PWREx_EnableFlashPowerDown(); HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI); HAL_PWREx_Disable...
Hello,I am using Zegbee messaging cluster on STM32WB55 to send messages between Zigbee endpoints and a coordinator.I would like to know the maximum number of end devices that can be connected directly to the coordinator and how high this number will ...
I have this code that initiates my UART channels with DMA at startup: if( HAL_OK == HAL_UART_RegisterRxEventCallback( m_configuration.huart, callbackRx )) { if( HAL_OK == HAL_UART_RegisterCallback( m_configuration.huart, HAL_UART_TX_COMPLETE_CB_I...
I am having issues debugging a STM32H7 series chip (STM32H755).When I connect using multiarch-gdb and run `mon swdp_scan` it crashes both cores. I am using a BMP debugger. I end up in the NMI handler. I can see via the external LEDs in the code that ...
I was using the preloaded demo for the STM32L476 Discovery board and everything was working, and then I followed the steps on the Getting started with STM32CubeL4 MCU Package user manual to try and run the first example. I followed the steps and once...
I am trying to evaluate the FDCAN function on a STM32U5 and somehow I don't manage to make it work .I can receive a frame when I am in (external) loop back mode and if the FDCAN transmits the frame but I cannot receive a frame in normal mode from an ...
Hi,I'm trying to perform analog-to-digital conversion using the DMA function on dual-core STM32H7 board series. Basically, I can not make it work. I have tried with other STM32 boards (like STM32L476RG for instance) successfully but it seems that the...
Hello,I have 2 EVAL board, one STM32H743i-EVAL2 and one STM32H7B3i-EVAL.Both have the same NOR Flash chipset MT28EW128.I'm using the function HAL_NOR_ReadBuffer to read data from the NOR.but, "sometimes", the data I read are corrupt.I made my project...
