SPI clock only giving 400mv
Hi I am trying spi master on the stm32h7 nucleo board, when I am measuring the spi clock it looks like it is only giving me 400mV max, can someone explain to me why and how to solve it? Thanks!

Resolved! DMA Flags not found (HAL Treiber)
Hello,I want to catch the half transfer and the full transfer flag from DMA controller but get an error and don't understand why.the compiler say first use in this function:'DMA_FLAG_HTIF5' undeclared (first use in this function)'DMA_FLAG_TCIF5' unde...
realize a dynamic display with stm32F401
hi,I have a projecte to realize with my stm , the idea of the system is :*sending images by smartphone to sd card which is connected to the stm board ,sending by using bluetooth or wifi communication.*display the list of images on lcd also connected ...
Is it possible to control the DAC via DMA with double buffering in an STM32F0 microcontroller?
I have DMA working in circular mode. However, after generating n cycles from a certain array, I would like to switch arrays without any processing time inbetween.I believe this can be done with double buffering. However, this doesn't seem to be possi...
Faster implementation of HAL_DAC_Start_DMA() to retrigger a single DMA transfer to DAC
I have configured a DAC to use DMA in single mode. I have created HAL_DAC_ConvCpltCallbackCh1(). In this function, I reenable the DMA process using HAL_DAC_Start_DMA(...), which appears to be really slow. How can I make this faster. I don't want to ...
What are the causes CAN macrocell remains into Sleep state?
Hi,I have a strange behavior on the bxCAN macrocells of a STM32F437 MCU and I'm here to askif someone has encountered the same situation.In my application I start programming one CAN module (say CAN1) to get some data sentfrom the other connected CAN...
Error/omission in RM0090: missing CC4NP bit definition
The CC4NP bit in the TIMx_CCER register should be listed in the reference manual in the section "17.4.9 TIM1 and TIM8 capture/compare enable register (TIMx_CCER)". Currently, only the CC1NP, CC2NP, and CC3NP bits are listed. The sections for the othe...
I am designing an PCB with an STM32H743 and IS42S16100H 1Mx16 SDRAM. I have two issues wiring up the SDRAM as detailed below.
The SDRAM has twelve address inputs A0-A11, where A11 is the bank select. In STM32CubeMX FMC section should I configure the SDRAM controller for 12 bit address and connect FMC_A0-A11 of the STM32H7 to the DRAM or configure for 11 bits and connect FMC...
STM32F2 Emulated UART
I have implemented an emulated UART on STM32F2 using the sample program from STM32F4. The UART TX data output is correct. Until a HAL_Delay(100) is add. When added delay, the UART TX output appears corrupted as shown below. Why is the HAL_Delay affec...
I am new to STM 32 MCU, it might be a basic issue I might be facing but couldn't find any solution in the documentations as well. When I am trying to connect STM 32 Nucleo and an IKS01A2 expansion board using a Unicleo GUI I am facing some problem
When I am trying to login to Unicleo GUI I am able connect to the communication port but the firmware description, version, expansion board name and library version in the login screen is showing unknown as I result , i suppose, am not being able to ...
