Hi, I'm using STM32L0 series MCU to configure the RTC to wake up after 24 hour during sleep/standby mode. Understand that we need to configure the Wake up clock to use 1Hz with 1 bit wake up counter added so that it can have the wake up time from 18h...
About once over 10, the MCU seems to hang after NVIC_SystemReset() call. Notice that:The MCU restarts correctly after poweron reset,NRESET set to 0 then 1 does NOT restart the MCUWhen MCU is hung, the NRESET Level is correctly UP (thanks to internal...
Hi,I want to get the PVD on a STM32H743 running in order to write some data to the flash, which did not work for whatever reason. So, as a first step, I tried to implement an interrupt which just pulls a GPIO-pin high and check it with an oscilloscop...
Posted on September 29, 2016 at 10:26 hello dear forum, I want sense F103 Power Down to save a variable to the flash of the micro however it doesnot save - doesnot work accordingly ( I tried saving to flash in another program - ...
We are making a board using stm32f767nih6. There seems to be a problem with RTC and Vbat while testing the board.First, we are using LSE with a 32.768Khz external crystal oscillator. However, there is a symptom that it slows down by about 10 seconds ...
Hi,I'm working with X-Cube STL STM32CubeExpansion package, want to know how many sections of RAM and Flash I can test on STM32H745ZI MCU, #define FLASH_SECTION_SIZE 1024U#define RAM_SECTION_SIZE 128U#ifdef STL_DISABLE_RAM_BCKUP_BUF#define RAM_BACKUP...
Hi,I'm working on an STM32L4R5ZIT6 mcu and I'm facing with the problem of switching the JTAG port to SWD without the use of a debugger (ST-Link or similar); reading the "Arm Debug Interface" document I found the way to make the switch and in fact, us...
Hi Expert, We are planning to use J1939 protocol for vehicle communication. We would like to clear few queries regarding this. Is J1939 CAN stack openly available? If no, do we need to purchase it? Is sample application available for communication us...
Hello everyone, I am trying to use the PSSI peripheral with DMA on my nucleo-H7S3L8, I am new to this GPDMA so at first i tried using the standard request mode and i got it working but it only receives once and stops do i need to manually enable it a...
Hi everyone,we're using the STM34F407ZG microcontroller in our BMS board.We have some issue during contact 8kV ESD applied in some screws above the boards. The ESD are applyed on all the screws but the problematic one are just 3 screws, the closest s...
