I connected STM32F401CCU6 board and ST-LINK/V2 with a SW called STM32 ST-LINK Utility. I'm sure it worked yesterday, but I don't know why it doesn't work now. The screen keeps saying "ST-LINK USB Connection Error" and plug in the USB and refresh, it ...
Hello,We would like to inquire about the abnormal operation of the RTC of STM32F427IIT6 included in our product. Please check the below.Used MCUSTM32F427IIT6BackgroundRTC is used for Log, so it is used very frequentlyIt has been 4 to 5 years since th...
Hi everyone,I am trying to generate an arbitrary PWM waveform using DMA burst write according to AN4776. It works in principle, except of one thing: If i want to have more than one pulse with a specifig period/pulse setting, the RCR should be used. H...
Hello, everyone. I hope you're doing well.my work at this time: https://github.com/MarginallyClever/Daisy-Driver-2.0-firmware/commit/465ec3dbeb831ee2f49fd6a6648da8fd7377a56aMy code is written in Arduino 2.2.1 with https://github.com/stm32duino/Board...
Can't post screenshots.RM0401 rev3 ('F410), RCC_APB2ENR contains EXTIEN. There is no such bit in any other STM32, EXTI is unconditionally enabled everywhere else. There is no respective reset bit in RCC_APB2RSTR. Is this bit real?in the same RM0401 r...
Hello, I am using STM32L4 series controller. I want to use USB OTG in dual mode where I want to run USB device and Host on same application. facing an issue when I select USB_OTG_FS as OTG/Dual_Role_device using cubemx tool then in middleware USB_HOS...
Hi, I am new to STM32CubeIDE. I am doing a PWM pulse generation project in STM32F411CEU6. After the configuration, I am successful in generating code. The debugging was also successful. But when I start Run, the message is popping up " No ST-LINK det...
Hi, I'm having a problem with unintentionally splitting a message I'm trying to send over the UART using DMA . I am using one function to send the message:const uint32_t max_value_of_counter_loop = 100; /* in case systick jams */volatile bool was_u1_...
Hello,i want to use a really precise PWM signal but i get a lot of Jitter on it.I am using the F410 with a 16Mhz crystal. The PLL produces from there a Frequency of 100Mhz (I need this high frequency for my other tasks).The rest of my hardware needs ...
I should combine STM32F479 with PROFIBUS-DP ASIC SCP4-2 The chip is aged. And requires delay of at least 30ns (by 3v3) between address and cs. Our previous design was based on SAM4S and their CPUs are offerring register to program such delays. In STM...
