Hi All,We have a project using STM32L431RBtx. In that we are trying to put MCU into sleep mode by using HAL API: HAL_PWREx_EnterSTOP0Mode(PWR_SLEEPENTRY_WFI) in bare-metal code base.Here the interrupt we have configured to wake-up the MCU from sleep...
Hello,I want to convert on ADC1 some channels in regular mode all the time. After a last Transfer request DMA2 Stream 0 should write all converted values in a global buffer. I also want to convert four ADC channels synchronous with injeced mode. So I...
My board(STM32F103R8T6) sometimes stop.. So I use IWDG and it doesn't work. If my board doesn't work well, is it right that iwdg works and resets the core? Let my code work properly.void IWDG_Configuration(void) { IWDG->KR = 0x5555; IWDG->RLR = 0x...
I am working with the STM32F7. I am implementing a DMA communications handler, preferably using the HAL (but LL is also an option that I have tried). I have successfully implemented the TX side of the equation but, am unable to get the RX portion to ...
Hello, I recently started with embedded programming and currently I'm tasked with LSI Calibration based on LSE clock, this would be useful when the device enters low power mode. Based on this reference manual:https://www.st.com/content/ccc/resource/t...
DS12589 Rev 1 (for G431) and DS12288 Rev 1 (for G474) both states in Section 3.5 that SRAM2 can be accessed by CM4 core through System Bus or through the I-Code/D-Code bus. However, Figure 2 "Multi-AHB bus matrix" suggests that SRAM is only accessibl...
Hi,I am working on B-L475E-IOT01A2 which is a STM32L475 series Discovery IoT kit and has an ARM M4 cortex. It has two banks of FLASH Memory of size 512 KB each. I am implementing two applications along with a bootloader and all of them are stored in ...
i config TIM with PWM , and insert deadtime , i found the first deadtime is longer than later , this why behave so ?
