I am relatively new to STM32 programming. I use STMCubeIDE (HAL & HAL_ex libraries) with STM32H743Zi and Nucleo-144. My configuration is:1 Multi Buffer DMA mem to peripheral, circular + clock triggered (54MHz per word, 360 words per buffer = 150 kHz ...
I assume this issue applies to DACs across all the MCUs but I am testing on a Nucleo-G431KB so I'll stick with the scientific facts.When I write a 12bit DAC value greater than 4060, the "down" slew rate in buffered output mode drops off a cliff.For...
Hi, I have a custom made board using a STM32L4 and I want to add some security to the data. So my flow diagram is: sensors get data-> data goes to L4-> L4 inicializates RasPi and passes the sensor data -> RasPi send back seured data to L4Is this some...
Can anyone please tell me the difference between VDD,VBAT and Voltage regulator in stm32f407vgt6 discovery board
Hello.I have assembled the device on the STM32L496ZGT6P microcontroller. Along with the other functions, this controller is to poll its UART interface (more precisely, UART4). The device is operated outdoors and at low temperatures, and I have notice...
Hi Everyone.Page 524, section 18.4.16 ADC timing of the STM32L476 Ref manual states.The elapsed time between the start of a conversion and the end of conversion is the sum ofthe configured sampling time plus the successive approximation time dependin...
Hello everyone,I am using ADC + DMA + TIMER for my analog samples on STM32 nucleoF401RE.I am new into the STM32 family.So I refer some code as per given some examples in this community.But I am not able to achieve it.I wanted to follow below method f...
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 ...
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...
