Hi, I configured PWM 25 kHz on Nucleo-767ZI to control the PWM fan.When I set up Duty Cycle 1% -3% and 98% -99% the PWM signal is deformed.When the Duty Cycle is 4% to 97% PWM signal is good.Can it be improved or is it normal?Regards
Hi all,I have the STM32F427VI connected using serial RS232 cable.I downlaoded the latest version of the Flash Loader and the parameters are Even/115200/Disabled/8I tried using jumper on boot 0, boot 1 and boot 0&1 but I can't connect to the MCU.Any i...
I am using an STM32F429VGT6 with SWD debugger, and OpenOCD software 0.10.0.I am trying to dump the contents of the flash memory at 0x08000000.If I don't use any WFE/WFI in my code, this works fine. If I put a WFE at the beginning of the code, before ...

The errata suggest to "insert a dummy phase with at least two dummy cycles" when using indirect data read mode.However, according to the documentation of the dummy cycle phase (AN4760 rev 3, section 3.1.4 and figure 8 ) states that in the dummy phase...
I am using STM32F103C for mcu and SPH0645 model for microphone.When I connect only one microphone and communicate with I2S it works!then I wanted to do make stereoSo I connected two microphones one with SEL=0 and the other with SEL=1However, WS gives...

Hi,First time poster here, I have looked around for answers and didn't find anything that could help me. I also tried to reach out to ST but they doesn't want to help and they are throwing me to local suppliers instead.So here's the thing, the ADC is...
Can anyone help me in understanding each part of the below function?static void FLASH_Program_DoubleWord(uint32_t Address, uint64_t Data){ /* Check the parameters */ assert_param(IS_FLASH_PROGRAM_ADDRESS(Address)); /* What's this? */ /* Set PG bit */...
I have a Nucleo F103 board on which I'm playing with some code to generate a variable bit rate FSK data stream. The code seems to generate the right signal but at twice the expected frequency.I have searched these boards and found one question for ex...
