Does stm32h7 at 480Mhz runs at 17MIPS only?
I have seen that it takes about 28 ticks to read registers, so I think my stm32h750 runs really at 17Mhz, it seems is not risk, so perhaps it exists another more fast stm32 micro that have more 17 MIPS

How to configure FIR filter in FFT USING NUCLEO-H745ZI
Hello Team,I'm trying to configure FIR filter in FFT in one point I am getting grab data every time in every call back collecting 1024 data and process to arm_fir_f32(); Function, is there any code related to this FIR filter in FFT.PFA code and sin w...
STM32H7 Internal Flash Error
I'm having trouble reading/writing to internal flash on an STM32H743XI. For a while I've been erasing/programming sectors of internal flash from a custom bootloader without issue but I somehow got the chip into a state now where 4 sectors can no lon...
Checking received Value from st ble toolbox app
HelloI have watched the lab about stm32wb55 where the board receives any event from the smartphone app and toggles the onboard LD2. Now i want to make mine specific by checking for the received value and only toggle the LD2 if its a 1 and only turn i...
Resolved! stm32h7 fastest gpio read using DMA
I would like read the gpio lines at fastest speed. As example it is possible to read first 4 ports by reading:uint16_t ports0123=GPIOC->IDR&0x000F; (it is very fast, takes 28 tics)It is possible to read ports GPIO_PIN_0-15 by connecting GPIOC->IDR to...

STlink-V3Set Low Voltage Error; Failed on OpenOCD init
HI!I am trying to program a custom STM32F446 Board using the SWD connections on the board. When trying to flash the custom board I receive the following error on OpenOcd: xPack Open On-Chip Debugger 0.12.0+dev-01312-g18281b0c4-dirty (2023-09-04-22:...
Resolved! STM32C011 nRST Problem
Hi,I started working on STM32C011J4.Systick, PWM, ADC, GPIO works just fine. Set pin4 to NRST_MODE 2 via STM32CubeProgrammer (v2.15.0) as GPIO. MCU gets stuck at reset if pin4 is low at power on reset. After applying 1.4V or higher to it momentarily ...
Resolved! How to detect STM32H573I-DK link status by HAL_ETH_ReadPHYRegister?
Hi supporter,I'm developing STM32H573I-DK and trying HAL_ETH_ReadPHYRegister to check link status. But this API seems be changed.Previous prototype is:HAL_StatusTypeDef HAL_ETH_ReadPHYRegister(ETH_HandleTypeDef *heth, uint16_t PHYReg, uint32_t *RegVa...
ADC Sample Time for Differential Channels Incorrectly Initialized when using HAL drivers
I'm using the HAL drivers to configure ADC1 Channel 3 as Differential and Channel 4 as Single Ended.According to the reference manual (Figure 143) when ADC1 Channel 3 is differential, it is Channel 7 that becomes unavailable as it is used as INN3. T...
