Documentation simple says the HSE clock failed. What does "fail" define. Does "fail" imply that there are no clock oscillations applied to the HSE pins? Or a frequency below some value that will set the CSSF flag in the RCC_CIR register. What would b...
Hi, I just want to give a short workaround for an issue i had with the NUCLEO F722ZE board. The CUBE-MX project (NUCLEO F722ZE selected - no custom build) does not work out of the box for CDC devices. In order to fix it i changed the default CUBE-MX ...
Consider: The pins are ultimately driving Power Mosfets, wherein the state of the outputs is of significant importance.However, between the time when one changes the MODER register(s) for the appropriate pin(s) to AF and the time when one changes th...
Hello everybody,I wanted to turn 2 LEDs with Timer on / off. The period is 4s and the first LED should be on for 2s and off for 2s. and then the 2nd LED should do the same but not at the same time. But unfortunately I can not do that with a timer and...
The Rev 4 data sheet for the STM32F030R8 lists the pins for SPI1 on both pins 20-23 and 50,55-77. I2C1 on 58-59 and 61-62, andUART1 on 42-43 and 58-59Which is correct, or are they selectable via registers?
HelloI'm trying to use DMA to directly write on GPIO port, and I've attached the code snippet I'm using to do so.But, I'm getting this exception which is stopping the DMA and fails writing data.Any thoughts?Regards.GPIO Init:__HAL_RCC_GPIOD_CLK_ENABL...
Posted on May 16, 2018 at 12:58Hi fellows, I have a issue when i exit the stopmode on my stm32h7.I notice that my power consumption goes down from 34mA to 5mA when i put my MCU in StopMode. But after the wake up from the StopMode i read 19mA. This i...
Hi,I use SWD interface to configure my STM32 board.It all worked out, but I changed #define and moved to a part of the program that disabled the sw interface.Now my STLINK/V2 can not connect to the device.Do you have an idea to erase the chip or rest...
Posted on March 16, 2015 at 10:58 Hi, I'm wrtiting a bootloader for updating an embedded product. Bootloader sequence seems correct now and I want to protect from writing the bootloader flash addresses. Using the snippets of code f...
