I am using stm32f429zi discovery board.When I am trying to use SPI peripheral, one bit shift in MOSI is observed with respect to Clock.It is tested in all modes of SPI, still getting the same result in oscilloscope. We are not able to understand this...
Working on a bootloader on the STM32F745 and starting from example code there was the function call CPU_CACHE_Enable.In the original examples, this is called right at the start of main(). I had moved this function call later as I (thought) I wanted t...
Hello,In my project, I sample the ADCs ( ADC1 & ADC2 ) every 1 millisecond. My ADC configuration :VREF = 3VFADC == 8M Prescaler = divide by 83 channels for each ADCSample time - 64.6 cyclesIn order to test my ADC driver, I inject 1HZ sinus. to 1 of ...
Hello,I have a board that use STM32F072C8T6TR reference. After severel weeks of normal use, the STM32 on some boards are not responding anymore. I tried to access the STM32 with STlink Probe, ore by using internal Bootlaoder, without success. After i...
Hello,All I / Os are CMOS and TTL compliant (no software configuration required).For example, as shown in the attached document, the VOH in Table 57 has a different Min value depending on whether it is a CMOS port(a side) or a TTL port(b side).When ...
abbreviations are extremely poorly described throughout the documentation. you have to turn on the fortune-teller mode to understand what is happening. in particular, the UG bit has not been "reliably" deciphered. all documentation is "raw" and made...
selected processor does not support `wfi' in Thumb mode mcu: stm32f103c8 - Ide: stm32cubeide how can I fix this error ?,thank you
Hello all!I am trying to play with the deep sleep mode of the stm32g031f8p6.Now i am using this: To sleep: SystemClock_Decrease(); HAL_PWREx_ControlVoltageScaling(PWR_REGULATOR_VOLTAGE_SCALE2); HAL_PWREx_EnableLowPowerRunMode();To wake up: HAL_PW...
I have a C project on an STM32F745 that uses various HAL libraries.Today I have enabled the WWDG (Windowed Watchdog.) I set the registers directly as I find that easier to understand and did this right at the start of main() to offer best protection ...
Hi, I am trying to communicate on CAN BUS, I have previously succeeded in doing so with STM32F103C8 and STM32F091RC, but I cant make it work on STM32F407VET It does not trigger its interrupt on message receive. What could be the difference on this MC...
