QSPI reading and Writing function not showing correct data

hi, I am trying to implement QSPI in STM32H743 with S25FL512. REad ID function work properly, showing correct data like command 0x9Fresult: {01}{02}{20}{4D}{00}{80} memory size 65Mbytebut the BSP_QSPI_READ/WRITE function not correct data, some one gu...

STM32H745 Disco, Simple Hello World and LED Blink

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 ...

How can I connect Gbit SDRAM to STM32F429?

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 ...

I am using STM32F417IEH6 on a custom-board with Azure_RTOS. The Azure_RTOS/ThreadX is working OK. I have several threads running.

 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...

When to stop TIM_DMABurst and how to first start TIM_DMABurst

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...

How to read the boot enabled/disabled bits in the user configuration option bytes of an STM32H7?

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...

STM32F732 Wakeup Latency

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...

What is the maximum number of end devices that can be connected to a coordinator in a Zigbee network.

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 ...
