I have worked with several STM32 Nucleo and Discovery Boards. My typical starting point is to print "Hello World" and blink an LED with from a HAL project. The HAL/IOC part is working as expected. I am thinking I am missing some dual-core hardware ...
Hello, I would like to connect Gbit SDRAM to STM32F429 MCU. When I look at the STM32 FMC memory map, it has two 256 Mbytes area for SDRAM. As far as I understand, I can connect up to 4 Gbit SDRAM. However, SDRAMs have maximum 512 Mbit size. 1) Is it ...
My board is supposed to act like a PM-bus server on top of a ATX-PSU and I need to 'time' the sequence, that powers up the PSU. I have tried to use 'tx_thread_sleep()' and even changed tx_user.h : #define TX_TIMER_TICKS_PER_SECOND --> 1000 an...
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...
