STM32H7 RAM Domain linkcmds modification error,

In H7 , RAM_D2 have 288KB size memory domain. Currently i'm looking to split this domain memory into two areas as below,MEMORY { RAM_INT  : ORIGIN = 0x20000000, LENGTH = 128K RAM_D1  : ORIGIN = 0x24000000, LENGTH = 512K RAM_D2  : ORIGIN = 0x300000...

SPI dma example receiving only 0

Hi I am using stmh7 nucleo board and trying the spi dma example in NUCLEO-H743ZI folder, but thr transfer only gives me 0 in the aRxBuffer, anyone has had this problem before? I am not sure how to solve thisThanks!

What kind of design path to follow while creating a PID for keeping temperature below some predefined temperature?

Hello, I am creating a Li-ion battery discharger. Only thing left is temperature control loop right now and I want to use PID for that purpose. I want to keep the temperature inside the device at max 95 Celsius. I am using PWM to set the discharging ...

Hi there! I'm using STM32L4 and I have found that my code runs only by debug mode but it doesn't by normal mode. However, If I set to use "Micro Lib" all works fine. What could be the reason? Thank you

The speed of the stm32 GPIO (different series).

Dear engineers. I want to read an extern parallel ADC directly connected to GPIO ports of stm32 microcontroller and clocked from it. It is necessary to make 1000 readings from the ADC with a maximum speed and write them to stm32 memory. What is the m...
