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...

How to stabilize the SDADC2 in STM32F373VCT6?

When I connect a voltage source to channel 0 of SDADC2 in single ended mode, then at floating pin and connecting to ground the value displayed is full scale which 65535, while when I connect some voltage like 2V or 3V to same channel then it shows t...

STM32F4 program crashes when interrupt is activated

Hello,I wrote a program for the STM32F4 using the Standard Peripheral library from ST. I compile the source code with the ARM-GCC tool chain and flash it on the chip using OpenOCD in combination with gdb. As long as I do not use interrupts everything...

Phase shifted full bridge control with STM32L processors

I understand that some of the STM32Fxxx series processors have timer peripherals that are specifically well suited for Phase shifted full-bridge control, but am wondering if the same is true of any of the lower power processors, like the STM32L serie...

Stm32h750 system flash bank 2

I would like to use the main flash sector for user data and use system bank 2 for code storage. Is it as simple as changing the linker script and the boot address so that code execution starts at the base address of the system flash bank 2?I can't se...

RM0038 TIM2_OR and TIM3OR: What is TGO?

Typo, or yet another internal signal name? I can't find "TGO" anywhere else in the manual by textual search.JW
