Resolved! How to properly enable all RAMs on a single core STM32H7?
Still learning H7 so apologize for a silly question.I want to use all Dx RAM parts on a single core STM32H743: D1, D2, D3.Now, in system_stm32h7xx.c , SystemInit there's following code:#if defined (DATA_IN_D2_SRAM) /* in case of initialized data in ...
Use DMA with SPI acting as a (simple) shift register?
I've (sort of) found out a way to store GPIO states in memory with DMA (parallel data input from a 74HC595 shift register, because the STM32F103Cx doesn't have 4 SPI peripherals) and I want to output that same data via SPI in a similar manner, except...

hi everyone,what's the problem with AP on the IoTA2, I can't set an AP, everything works great only the AP doesn't work?can someone tell me is there Something with the fw?
What commands should I send through the Serial COM port to a Nucleo-F401RE board via a Python Script and Command Prompt to replicate the Connect and Start options in Unicleo-GUI?
Hello All,I am using a NUCLEO-F401RE Board and a IKS01A2 Sensor Board with it. I want to collect the incoming data dynamically and modify it. By using Unicleo-GUI and just clicking Connect and Start I am able to observe the collected data. I want t...
Timer: No complementary output in one pulse mode?
Does one pulse mode offer the complementary output? My complementary output just sits there. I'm on TIM17 and I'm not sure if being on the 'lite' timer is the problem. I suppose I'll try moving it over to TIM2 and see if the problem persists althou...
TIMER one pulse mode with variable time delay?
i want to generate pulse which on time is fix(100us) but off time is variable(between 0-10ms) and it is synchronous with external interrupt how can i do this using HAL libraries ?
Systick and I2C DMA -blocked by EMP(Electro Magnetic Pulse) Attack (STM32F030R8T6TR)
My work environment is heavily disturbed by EMP which particularly has frequency of 2.44GHz. I measured the frequency and 2.44GHz is most frequently affecting, but 900Mhz range has other influences to MCU operation.Sometimes, ST-LINK V1 and V2 is dis...
H745 memory regions, attributes & cache
In the h745 reference manual, the RAM region of memory is write-back while the code region is write-through. According an app note, cache coherency issues can be avoided by using a write-through ram region. In the h7 the sram sections are aliased in ...
