I am using stm32f302r8t6 microcontroller. In standby mode, the pins on port A are high, which should not be the case for the card I designed. For the stm32f302r8t6 microcontroller, I should keep one pin on port A low in standby mode.
Hi, I have set the timer4 in center alligned mode 3 and I want to trigger ADC on counter overflow. If I understand correctly the ADC trigger input TIM4_TRGO can be set in timer configuration as update event output but that means also in underflow wil...
Hello,We use standard driver libraries for STM32F10x and STM32F4xx. Looking for list of bugs reported on these. The previous link doesn't seem to exist anymore https://community.st.com/s/topic/0TO0X000000BWVLWA4/bugreport.Please help in getting the n...
HI experts , May you have a nice day! this figure is in rm0440-STM32G4 Series Reference manual. STM32F4, STM32F3 have the same TIM.now I have some question:1. how can I configure the Modules in the red box, such as selecting x0, 01 or 11?2. I fi...
Hi ST community,For a project I would like to generate two interdependent PWM signals (Sa and Sw in the attached figure) with the STM32G0. The constraints/tasks are as follows:tSw,off = constant for ~100nstSw,on = in a time range from ~100ns to 20us ...
Hi, thanks for reading my question.I use DMA for ADC, and it works well, one shot mode, and starts gain, data changed well from the ADC.But, if I read the data, then DMA works but it cant write it into the memory. #define MAX_DMA_MEMORY_SIZE 2552 A...
I there a way (device or API) to control STM32 resources via JTAG or SWD without the need to downloading a custom program? For example, setup GPIO pin with pull-up and direction and then write value. In addition, be able to perform more advance sce...
Hi all,I'm unable to switch the internal regulator from the default LDO to the SMPS on the STM32U599NIH6Q. The function "HAL_PWREx_ConfigSupply" timeouts.The same binary file, when flashed on the two different STM32U5 dev kits (NUCLEO-595ZJ-Q and STM...
Hi, What is acceptable ripple voltage on power supply pins on stm32? I am using DC/DC converter and have 100mVpkp at the output (+3.3V). I tied VDD and VDDA pin to one power supply as I am not planning to utilize an internal ADC. I am just planning t...
I want to switch clock source for decreasing power consumption(WakeUp->MSI->HSE->MSI->STOP2->WakeUp->MSI->...). I use HSE(12MHz) for SYSCLK through PLL(24MHz).MSI is set 24MHz.I have three probrems.HSERDY doesn't RESET when disabling HSEAfter enter...
