Hello team, I am trying to connect external NAND flash with STM32H753ZIT6. my concern is with respect to FMC_ALE and FMC_CLE pins as, in Pin no. 80 and 81 these are multiplexed with address lines whereas pin no 98 and 99 can also be used as FMC_ALE a...
Hi all,I buy a nucleo-h7s3l8 but I don't how to program and debug itH7s3l8 mcu is different from other stm32 mcu that I use beforeMy question is as followsIf I use STM32CubeMx to create project.I will get two subproject boot and appli in Stm32CubeId...
Hello everyone, I have a board.STM32F429I DISCO1, I want to read, say, two bytes of parallel data from port A{15:0}, into the DMA buffer, every time a rising edge of some signal comes to the microcontroller from the outside.How exactly can this be im...
I am facing the problem of data integrity, the logic is something as shown below i am taking the CAN rx data from the interrupt and processing in while loop. uint8_t g_candata_u8=0; int main(void) { Initilializations(); while() { if(CanMess...
Hi everyone,I cannot start SWO trace (nothing received in debug window) with STM32F103C8T6. Here is my main.c file: /** ****************************************************************************** * @file : main.c * @author : Auto-generated by S...
Hi,I want to use the RTC timer on the STM32WB to run FreeRTOS in both normal and STOP modes (For HAL time base I use Systick). When the MCU has no work, it goes into STOP mode. If the MCU needs to wake up for timing, like from a FreeRTOS timer, I set...
Posted on February 13, 2018 at 13:16The current data sheet for the STM32F303CC (DocID023353 Rev13) shows on page 80 the characteristics of the LSI oscillator.Its frequency starts from min. 30kHz to typical 40 and max. 50 kHz (all at 3.3V in the max....
When SRAM1 is remapped at 0x00000000 address space using SYSCFG_MEMRMP register, SRAM1 cannot be accessed by DMA by its remapped zero-based address. DMA error occurs at the very first transfer and DMA channel becomes disabled.Steps to reproduce:1. Us...
Hello, I have a question regarding PG pins PG0 to PG10.Can any of these pins (PG0 to PG10) be used to provide a PWM signal at around 20kHz. Thank you in advance
Hi,I stumbled across a problem with the LSI when i realized, that my IWDG was about 20% faster than it should be.The clock is behaving very irregularly, this is more than the deviation in the datasheet. I read out the LSI from PA2 with an oscilloscop...
