Resolved! Get STM32H735G-DK out of deadlock!

I can not connect my STM32H735G board via ST-Link anymore. "no stm32 target found". I tried "connect under reset" (ST Link Utility and ST programmer) as well as connecting boot0 to VDD. Any idea how to erase the flash and start over? Cheers Stefan


Hi,I'm currently using the STM32F103 SPI to read the MKI194V1, but I've noticed that the ID I'm reading is always 0x4A. Could you please help me check if there's an issue, or provide any sample code?I also take a photo of the MKI194V1. The marking on...


Incorrect address of TIM1 in STM32NUCLEOF302R8

Recently while using the TIM1 feature in NUCLEOF302R8(DOCUMENT NUMBER:DS9896), I've found that the address was wrong in the datasheet but the address of TIM1 in SFR is correct when I tried the address in SFR's It worked.   I'll list the findings that...

ADC Readings Lower than Ideal

I am using an STM32L562VET6Q MCU.  I have been having issues getting a valid reading from the ADC.  The signal is essentially DC (i.e., no fast high frequency measurements) so I conservatively set the ADC sampling time to its maximum.  My reference v...


Resolved! choosing flash latency vs. VOS

Giving an example for my question. For STM32H563, for freq. 140MHz, it is possible to use three different configurations:- 4 WS, VOS2- 4 WS, VOS1- 3 WS, VOS0If I want to optimize for power, I should choose 4WS VOS2. If I want to optimize for performa...

Resolved! STM32U585 Azure IoT migrate to BG95

I'm trying to migrate my Azure IoT application from a BG96 to a BG95-M3, both from Quectel. I have solved some problem due to the difference in use of the uart3 pins of the BG96 and BG95. Should I make more modifications to the software? Is there a d...

Resolved! Real time changing AHB,APB1 Prescaler, Sampling frequency

Good evening,I am trying to sample various signals at different frequencies with adc in dma. Changing the size of the acquisition buffer seems inefficient, so I opted to change the clock prescalers, but it's giving me problems (I guess on changing th...
