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 ?
Hi,I am trying to use an e-paper and a STM32L053C8 microcontroller.When i use the display in the first cicle, all works fine, but after wake up from stop mode, the display not works. Maybe the SPI interface not start well or i am doing somthing wrong...
Hallo.I want to use OSPI to feed an external DAC with data.Data shall be transfered through DMA from memory to OSPI. Eight bits and OSPI-CLK shall be used.In the first place I set up OSP in octo mode, disabled all IRQ etc. and tried to write one byte...
