Hi everyone,Is anyone can explain the SLEEPDEEP bit from SCB->SCR with more information than the pm0214 stm32 cortex-m4 reference manual?Controls whether the processor uses sleep or deep sleep as its low power mode: 0=Sleep, 1=Deep SleepWhat i want t...
Hello everybody, I am developing a bootloader that is currently writing to flash, but I am not being able to jump to the written blocks.The bootloader runs from 0x8000000. Built with arduino_stm32.App starts at 0x8009000.I can test the app with the l...
Hi there, i am using STM32F401RE development board and using PWM generation using DMA. I am following register level programming approach and here the issue lies in the DMA settings. Like if I set my PSIZE and MSIZE to 32-bit long and also if my data...
Hello,I'm attempting to set up the CN13 USB port as a Virtual COM Port (VCP) for transferring data to LabVIEW. Unfortunately, I'm encountering an error message that reads "Unknown USB Device (Device Descriptor Request Failed)." I've already installe...
Hi,I´m trying to develop an external loader ("EL") for my custom combination of an STM32G070RB with an external Flash in single SPI connection (M95P32-I). I´m using:- SMT32CubeIDE Version: 1.13.0- STM32CubeProgrammer 2.13.0My EL is being accepted by ...
Hey!I'm trying to use ST-LINK/V2-1 from Nucleo to program and debug my board. I removed the jumpers from CN2 and connected CN4 to my board according to the manual:Problem occurs when I tie NRST of the CN4 to the STM32 on my board - in this case "DEV...
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...
I am having some strange power up (I think) issue with my STM32G431 controller. Sometimes it runs for a second or two, sometimes nothing. It will usually not connect via the SWDIO pins so it is difficult to step through in debug to see where the pr...
I am using STM32F103C8 MCU and Trying to communicate with Quectel EC200U-CN 4G module and i am not getting data through UART2 Receive pin. Please go through my code and suggest mevoid USART2_IRQHandler(void){ if ((USART2->SR & USART_SR_RXNE) != RESE...
Hi, i m trying to program PowerStep01 with SPI on STM32H7, can anyone kindly advise where to locate sample code and tutoral ? or programmer user guide? A serach online yield this but error on page and file not found. https://my.st.com/content/my_st_...
