Resolved! STM32G484VE - GPIO status while powering on.
I have designed a target board based on STM32G484VE and I am encountering a problem with GPIO outputs while powering on.The requirement is no output should get high status while powering on or during reset. So I have configured the IOs using CUBEMX ...
Resolved! [B-U585I-IOT02A Discovery kit] What is the maximum voltage to apply to VIN ?
Hello,I'm currently using and working on B-U585I-IOT02A Discovery kit. Today, I supply the board with STLINK source via CN8 connector. But I want to be able to supply it with 12V voltage. So I will now supply the board via VIN pins and connect jumper...
Which stm32 MCU can do fastest DSP, arithmetic & floating point calculation?
I want to make robotic arm , CNC controller for this purpose which STM32 is capable to do DSP, arithmetic and floating point calculation Faster (less clock cycle for execution)without much execution code delay?So interpolation and trigonometric fu...
Resolved! Timing to be reflected __disable_irq() and __enable_irq()
We make below code.The variable a is written from both main function and interrupt function.When accessing variable a with the main function to realize exclusive control, interrupt disable and enable (__disable_irq(), __enable_irq()) are used.How ...
How to remove automatic ARP Broadcast messages ?
I am working on this project and I want to have full control of the sent / received messages from my STM32F746G. Even when starting an empty project without ETH these messages are sent from the STM
Hello , I am trying to read address from GP30 using spi as an interface between stm32l476RC and to transfer it to pc via UART, there is no errors , i have reversed the programmer using Cube Programme but I am not able to see data sent .please help

Error Code Writing to FLASH On STM32L496
I have a project based on the L496. The application does a few writes to FLASH. The initial write works correctly, however subsequent writes fail. The code is directly from STCube:/** * @brief Wait for a FLASH operation to complete. * @param Ti...
HAL_FLASH_Program returns with error
Posted on January 25, 2018 at 14:07Hi,I use STM43L476 and try to use fast flash program to program 256 bytes (decripted_firmware_data buffer).The flash area is erased (all 0xFF), but the function HAL_FLASH_Program always returns with HAL_ERROR and n...
