I try to use TIM_DMABurst to generate exact number of pwm pulses.But I found after call HAL_TIM_DMABurst_WriteStart and HAL_TIM_PWM_Start, it enter HAL_TIM_PeriodElapsedCallback. And then if I call HAL_TIM_PWM_Stop it will stop and generate no pwm. I...
Hi all,in the STM32CubeProgrammer section Option bytes (OB) there's one group called "user configuration". This group list the two checkboxes BCM4 and BCM7 to enable/disable booting each core. I assume that there are two bits in some R/W configuratio...
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...
