Capture peak value through ADC

I am using the STM IoT Kit Node and have a current sensor (voltage output) connected to the ADC.I can read the current through the ADC by reading the counts and doing the correct conversion. But I'm trying to read the instantaneous peak current (the...

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
